Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around



I switched to Rogers 2 days ago and bundled Ignite 60 internet, home phone and Basic tv services.


I am having some wifi connectivity issues my 2009 Macbook Pro.  I've been reading a ton of threads in this forum but nothing quite matches my situation, so I'll try to give as much info as I can.


I have the Hitron CGN2 modem. We have 4 devices connected to the wifi - my MBPro, my husband's 2015 Acer laptop (6 months old), and 2 androids: brand new Samsung Galaxy and a 2yr old Samsung Note. My husband's laptop and both androids connect to the wireless with no problem, although speeds are slower than advertised, but definitely still useable at 24mbs download and 8mbs upload. When plugged in via ethernet, the speeds are 75mbs download and 10-11 mbs upload.


My MBPro is having huge issues though, and what I'm trying to determine is if it's because my laptop is just an old fart and I need to replace it to use the internet, or if there's another issue. However, I had Bell before this and connected to the internet just fine.


The MBPro is getting download speeds of 0.10mbs and upload speeds of 2mbs. And that's when I could even get a speed test to run. Mostly, it just doesn't work.


Here's my CM Status stats:

When I found this info, I also found a list of every other local wifi network. I live next to a medical building so there are a LOT. Most run on channel 1. I've tried switching the channel to a different one (6, 7, for example) and I'm already running at 20mhz.


Here's the signal strength info:

MAC of WIFI client RSSI0 RSSI1 PhMode BandWidth Data Rate
Samsung Galaxy -81 -75 11N 20MHz 78Mbps
MBPro -41 -42 11N 20MHz 130Mbps

I've also got it running at 11N only, to see if that made a difference. So far, nothing.


I haven't called Rogers tech support yet because I've been at work since they installed it. I'll try calling later on today.


My ask for the smart folks here:


1. Is it just because my laptop is old and cranky?
2. Or would buying a router and running the modem in bridge mode fix it?

3. Is there anything I'm missing that I could try?


I'll report back with anything Rogers tech support might have to contribute, but based on other threads here, I thought I might have more luck with the people here since it works for every device except one.

I haven't bought inSSIDer yet - was hoping to not have to spend $20 unless I had to.


Thank you so much!

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@artgirl, the question on signal processing affecting video calls is an interesting one.  I don't recall anyone saying that the problem affected any type of video conferencing.  Gamers are usually the first ones to see this as there is a latency indicator built into many games, so gamers are usually more aware of overall system latency when they're gaming.  Does this have the potential to affect video conferencing?  Possibly but I can't say that it definitely will have any effect.  The signal processing issue is due to the increased number of downstream channels that the new modems process and the processing itself which is done in software.  Hitron is now experimenting with running that channel processing in hardware.  Hopefully in a month or two at the latest, we'll see positive results.   This issue has only come to light very recently with the fielding of the CGNM-3552 gigabit modems and the change over to the Casa CMTS equipment that started around the middle to end of May I believe.


So, the trade-off now, if you move up to the CGN3ACSMR "Rocket Modem" is a possible latency issue versus immediate access to a 5 Ghz network.  You can always go back down to a CGN2 if you find any real problems with video conferencing.


In any event, from what you are describing of your apartment, you will most likely require a router with better wifi performance, no matter what modem you are running.  And, you might find that switching to a set of high gain antenna will give the router the ability to reach most if not all of your apartment.  


There are a few ways you can provide the reach to the back of the apartment.


1. Use a router with external antenna to give you better overall wifi performance. Add high gain antenna if necessary.


2. Use a powerline adapter set to provide internet to the far corners of your apartment. These plug into the electrical socket and use the home electrical cables to carry internet data. You would plug one adapter into the modem or router via ethernet cable, where the modem or router is located, and plug the other adapter into a socket where you wanted to access the internet.


The performance of these adapters depends on the total line length from one adapter to another, the particular path that is used and on the amount of electrical noise present in the electrical system.  They would probably see their best performance with a pair of rooms where those room electrical breakers were located on the same side of the electrical panel.  So, the data path would be from the wall socket, to the electrical panel, up or down the bus bars at the back of the electrical panel,(on the same left or right side of the panel), and then out to the other adapter's electrical socket.  So, if it happens that the room where the modem is located, and your office are connected to the same side of the electrical panel, left or right, then, this might be an workable option.  How well would this work in an old apartment building with potentially old wiring remains to be seen however.


There is a new generation of powerline adapters out on the market now that utilize the new HomePlug AV2 standard.  Basically this means that these adapters use all three lines of the electrical system for the purposes of data transmission, whereas the older adapters use only one set of electrical lines. So, the newer HomePlug AV2 adapters can have much higher data rates.  Most powerline adapters are only ethernet to ethernet, however, there is one out now that has an 802.11ac wifi transmitter at the remote end, in addition to ethernet ports.  This is the only powerline adapter set out on the market with 802.11ac wifi capability.


If I was going to look for any powerline adapter I would only look at HomePlug AV2 adapters. The AV2 indicates the most recent standard applies to a given powerline adapter set, and, if I was interested in wifi, specifically 802.11ac at the same time, I would look at the TP-Link adapters first.

3. The next choice might be a range extender. I haven't looked at any of these, but bring this up as another alternative.  Essentially its two wifi transmitters in one.  It is used to detect an existing network, such as a 2.4 Ghz network and rebroadcast that on another 2.4 or 5 Ghz channel.  So, it would sit halfway to where you wanted to extend the network, usually plugged into a hallway electrical socket.  I've never looked closely at these, so I don't have any recommendations to make.


4. The last recommedation is to improve the wifi capability for your back office computer.  There are a couple of new products out on the market now, designed to extend wifi range by using a USB port connection, or thru the installation of a wifi card in a desktop.  The first is a Trendnet product that plugs into a USB port so it could be used with a desktop or laptop.


The second is a wifi card that would be installed on a desktop:

So, looking at these, yup, they're a little ugly to say the least, but, the goal, which isn't stated in the marketing is to use a high gain antenna to squash that vertical power distribution down so that you end up with more power in the horizontal plane and therefore increased range and data rates and provide directional capability as well. Same idea as installing high gain antenna on a router.  If I was looking to to connect a computer that was hidden in a back office somewhere, I'd be looking for one of these to try out.  The question that goes with this is whether or not you would be able to use Rogers Hitron modem up front, and use one of these for the back office.  That would depend on whether or not the Hitron modem would provide sufficient 2.4 and 5 Gh coverage for the rest of the apartment.  If not, then you're looking at a router up front, possibly with high gain antenna, and one of the add-on systems for the back office.  It all depends on what you see in terms of power levels and any interference by using inSSIDer, and also on the wifi data rates that you see at various points around the apartment.


Just as a reminder, the freebie version of inSSIDer doesn't detect or display the 5 Ghz 802.11ac networks that are present, so it doesn't provide a complete picture of the 5 Ghz networks.  The new version will do that, even if its running on a normal 802.11n wifi laptop.  The application reads the transmit headers that are used in the wifi protocol and displays the data for the 802.11ac networks.


The metageek website leaves a little to be desired for organization, so, here's the download link.  Select the personal version if you're interested in purchasing it:


Here's the link to buy the personal edition:


From that page comes the following for the mac:


System Requirements — Mac Version


OPERATING SYSTEM: OS X 10.8-10.11 (Mountain Lion, Mavericks, Yosemite, and El Capitan)
Note: inSSIDer Office for Mac (beta) only supports Mavericks, Yosemite and El Capitan
WIFI RADIO: Airport Card (USB WiFi not supported)


Don't know if the mac info helps or hurts the cause.....


Ok, lots to think about and consider. Hope this doesn't muddy the waters too much 🙂


Please let me know if you have any questions.

Re: Hitron CGN2 verrrry slow wifi for one laptop only



Hello, @artgirl


Welcome to the Rogers Community Forums! Smiley Happy


Thank you for posting your concern in the Community, I appreciate all the details of your post. It's good to know that your modem is delivering 75/10 Mbps of speed on a wired connection. 


You've mentioned that you are running the CGN2 at 11N only, have you also selected WPA2-PSK/AES in the "Security" section? Have you tried running diagnostics on your MBPro yet? You can click on WiFi icon/Make sure WiFi is selected/Assist me/Diagnostics and complete the prompts. It may help your MBPro connect at a good speed. If you are able to connect at good speed after running diagnostics then your ask#2 will be helpful. 





Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

Hi @RogersMoin!


Thanks for the welcome and the speedy reply. 🙂


I have selected WPA2-PSK/AES in the "Security" section. When I ran WiFi diagnostics, it told me that my wifi connection was working great.


Do you know of anything else I can check, just to get more helpful info for troubleshooting?



Re: Hitron CGN2 verrrry slow wifi for one laptop only

@RogersMoin, is @artgirl eligible for a CGN3 with her current plan.  That would allow her to use the CGN3's 5 Ghz wifi capability, which might help.


@artgirl the CGN2 is only a 2.4 Ghz wifi modem.  You could download the freebie Windows version of inSSIDer as linked below and install that on the Acer laptop,which I believe is a windows laptop.  That will allow you to to have a look at the wifi environment to see what you're up against and determine if you really need to be running in the 5 Ghz band.


The mac version link on that page is apparently linked to a pay version.  As I don't know what version that is, if you really wanted to run it on the MAC, you would be better off going thru the inSSIDer web site to obtain the latest version.   For now, using only the 2.4 Gh band, the freebie version will do just fine.


Would you happen to know if the bell modem that you were using before was 5 Ghz capable and if possibly you were using a 5 Gh wifi channel.  That might be one reason why you see such a difference.


If that was a windows laptop, I would recommend deleting any wifi network profiles from the laptop and then reconnecting to the modem.  When changing modems or routers people can often run into issues just like this where the old profile contains the connect details of the old modem or router.  Maybe that includes the old MAC address and other hardware specific details of the previous network, speculating at this point.  Is there a facility on the MAC to delete previous or existing networks?  If so, I'd recommend giving that a go.  


Just to comment in general, the Hitron modems are not noted for their wifi performance.  I would recommend moving to the CGN3 series if you're eligible, and failing that, if wifi performance is a top consideration of any modem or router, you might want to consider buying a good router that will provide that performance, one with gigabit WAN and LAN ports, external antenna and 5 Ghz 802.11ac capability. 



 Edit:  @artgirl, the CGN2 lies horizontally, whereas the CGN3 series stands vertically.  Just to check, can you confirm that you have a CGN2?  Dumb question possibly, but I didn't think that Rogers was handing those out anymore.  If you do have a CGN3 instead, can you look at the product sticker at the back of the modem and let me know what version of the CGN3xxx you have.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@Datalink - I believe it's the bundling effect since CGN2 can support 60/10 Mbps will result in $4 savings as oppose to CGN3. -RogersMoin

Re: Hitron CGN2 verrrry slow wifi for one laptop only

Hmm, interesting. The $4 difference might not be worth the aggravation.  Its possible that @artgirl might need to use a 5 Ghz network which inSSIDer would demonstrate pretty quickly.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

@Datalink - thanks so much for such a detailed response!


1. Definitely CGN2 - it's horizontal, and I checked the details on the bottom before posting.


2. Bell - I just checked and it was a 2.4GHz modem (Home Hub 1000, Sagemcom Fast4350)


3. I can delete previous networks and did delete the Bell one earlier, but I'll try deleting all of them and see what happens.


4. I'll give the free version of inSSIDer a go on the Acer and report back with what it tells me.


I am starting to think that investing in a good router might be the best way to go regardless - we have a large-ish rabbit-warren-style old home and we realized we'd need a signal booster anyways. (The Bell modem line was in the middle of the house, the Rogers cable at the front, so we're noticing we can't get wifi in the kitchen anymore.)


I'll try these things out and see what happens!


Thanks! - artgirl

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@artgirl, remember that you can park the modem wherever you have a cable outlet.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around
@Datalink Unfortunately, we've only been able to find the one cable outlet thus far. But that's good to know in case we spot another!

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@artgirl if you have a newer home, built within the last 15 to 20 years, you might have structured wiring, which is a multi-cable bundle that runs up from the basement to one or more locations in each room.  That bundle consists of two RG-6 cables for cable TV / satellite, one Cat 5 or 5e cable for data, and one Cat 3 cable for telephones use, possibly a Cat 5 cable instead.  If you look behind any wallplate that has a telephone, cable or ethernet port in it, you might find the rest of the wire bundle behind the wall plate, waiting to be discovered by the home owner and put to use.  Contractors will typically install a single outlet, telephone or cable and leave the rest for the home owner to find and figure out.  If you do have that cabling installed, you can use the ethernet cabling to run data all over the home, which makes situations like yours much easier to resolve.  That would allow you to buy a router and park it in a different location somewhere in the home to provide better wifi coverage.  

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around
@Datalink - yeah, this place was built in 1925 lol. When I said old & rambly, I meant it! It has a LOT of wires, but as we've discovered, most of them go to nowhere and are cut telephone wires. (And it's an apartment, so I can't really speak to what sort of cable maintenance has been done here, but based on my experience thus far, the bare minimum to stop the house catching fire.)

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@artgirl, been there, seen that.  No fun.  You have a different challenge then, and that is to find a router that will work in that type of environment.  


Fwiw, I and others in the forum use an Asus RT-AC68U.  No complaints what so ever.  Mine has been rock solid and is only out of service when I update the firmware.  This has been superseded by the RT-AC1900P.  Same router but with a 1.4 Ghz processor instead of the 800 Mhz processor in the 68U.  My only concern is cooling the 1900P given the 1.4 Ghz processor, but, I haven't seen any issues listed anywhere.  


The 1900P and 68U are on sale at a couple of locations:


One thing to keep in mind, given that your in an older apartment, if its a single floor apartment, a router with so call high power antenna, or a normal router with antenna that have been switched to a high power version would probably help.  The 68U/1900P and most other routers arrive with typical 3 to 5 dB gain antenna.  The high gain antenna can go much higher in terms of final gain figures.  What they do is squash the normally round, ball shaped power distribution around the antenna into a shape that is flatter and therefore has greater horizontal power distribution, so that gives the user increased receive power at the remote devices and gives the router better signal sensitivity to detect those devices at greater ranges.  TP-Link makes a router or two with longer antenna which might do the job.  If you went the route of buying a router with typical external antenna and switched to a high gain variety, you have to be careful as you would need a dual band antenna, which works on both 2.4 and 5 Ghz bands.  Some high gain antenna are only designed to operate on the 2.4 Ghz band and would damage the router if the 5 Ghz band was used.   


If you're in the market for a router these days, another question is, do you buy the new technology router now or later. New routers are Multi User Multiple Input, Multiple Output capable.  The Multiple Input, Multiple Output simply means that the routers and remote devices transmit and receive more than one data stream at the same time.  Thats been around for a few years now.  The Multi User part is new.  That means that the router is able to transmit to 4 devices simultaneously and receive from them individually, in sequence.  So, if someone had a large number of brand new remote devices, which support that Multi User signal format as well, then he or she would see very fast data rates across all of those devices, at the same time.  That technology has been on the market for a few months now, but, realistically, it will probably be many years before the average laptop/cellphone person has replaced the current technology devices and can then use that Multi User capability.  


Current tech routers service all of the remote devices one at a time.  When the wifi channel goes quiet, the devices essentially run a race.  The first one to transmit wins the race and is then able to transmit and receive data to and from the modem / router.   Tried and true, so to speak, this technology will be around for a good number of years to come.  


In terms of any router, I would recommend either Asus or Netgear for their router updates.  Not to say that their perfect and absolutely head and shoulder above the rest, but both companies produce updates for their modems.  I have an issue with Netgear as they apparently filter ICMP packets for IPV6 and refuse to reverse that position, at least from what I've read to date.  If you haven't kept up with the state of internet addresses these days, the world has run out of IPV4 addresses, such as the typical that you use for the modem or router.  So, IPV6 is coming into use, with addresses such as:  2001:4860:4860::8888 which is google's IPV6 DNS server.  IPV6 requires Internet Control Message Protocol (ICMP) packets in order to work.  Scratch Netgear due to their filtering of ICMP.  Rogers has enabled IPV6 recently across the network and is completing all the the configuration changes required at the various servers.  I don't believe that all of the changes are totally complete, but they are probably getting close.  


So, hopefully that provides some food for thought.  A good router with the right antenna would probably make your wifi use trouble-free.




Here's an example of a 12 dB high gain antenna set.  You would need three of these for an RT-AC68U or RT-AC1900P.


Here's a slighly lesser 9 dB gain antenna set:


Here's the Amazon listing:


Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

@Datalink - you are a rockstar. Thank you so much for such a thorough review of routers and what I need to look for. We are on one floor, but lots of rooms and walls to go through, so those recommendations are great. I'm actually looking into replacing my laptop within the next few months, which means that most of our devices will be brand new so Multi User may actually be something for us to consider. Either way - thank you! Super, super helpful.


So I actually have an out-of-use 2011 HP laptop that I've got inSSIDer up & running on. (Hilariously, it's connecting to the wifi the most strongly - it's actually getting 55mbs download speeds, faster than any other device in the house. I'm officially baffled!)


What sort of information am I looking for on inSSIDer that would help us troubleshoot? Anything I can copy and paste here for you?


- artgirl



Re: Hitron CGN2 verrrry slow wifi for one laptop only

What you want to see on the graphical display is that your network is the highest network shown, which indicates that it has the highest received power of all the received networks.  Generally you want somewhere in the neighborhood of 40 to 45 dBmW separation between your network and any other network that is on the same or overlapping channel.  So, while your network should be the tallest on the display, everything else should be well below yours.  The scale on the display has 0 dBmW at the top, and it then descends from there.  When the power level separation between networks decreases, you end up with interference and possibly with problems maintaining a wifi network.  Your only option is to change to a channel with less overlap from the competition.  By looking at that display you might conclude that the 2.4 Ghz band is hopeless and that its time to move up to the 5 Ghz band, if you can.


So, with inSSIDer loaded on your laptop, take a walk around your home.  Take a look at the display when you're close to the modem, and where you normally use your laptop.  Essentially, you're doing a site survey. It takes about three to four minutes for the display to settle out when you move around and stop in a location somewhere.  You should see some differences in the received network power levels as you move around your home, both for your own network, and those of your neighbors.  Perhaps one of your neighbors has bought a new modem or router and is competing for the same channels that you are using.  If so, inSSIDer will show that.


What you can do is take a screenshot of the inSSIDer display, dump it into something like Microsoft paint and wipe out your MAC address from the text and display area and then save it.  Insert it into a post so I can have a look at it if you need help with the interpretation.  With the info provided by the inSSIDer display it will be easier to determine what the problem might be.


Here's some additional food for thought.  Have a look at your MAC and see if there is an IPV6 enable/disable checkbox.  If there is, disable IPV6 and reboot the MAC.  IPV6 is enabled on the CGN2, so, just wondering if it has anything to do with the problems.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

Fiddling with IPv6 now. In the meantime, here's a screenshot of what inSSIDer is showing me. It looks like my guest network is the only thing closest to my own, at least when I'm sitting right next to the modem.


I'll take inSSIDer on a walkabout too.



Re: Hitron CGN2 verrrry slow wifi for one laptop only

One of the mods will have to approve the image so that its publicly available, so that will take a few minutes.  I should have stated earlier that you want to see somewhere in the range of -30 to -40 dBmw for your own network power level.  Anything much below that and you can have problems connecting with the network, even if there is no interference from neighboring modems or routers.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around
It's generally in the -30 to -40 dBmw range. So that's something. I've seen it vary from -33 to -50 so far.

The router is *definitely* looking like the way to go at this point!

Re: Hitron CGN2 verrrry slow wifi for one laptop only

@artgirl, looking at your inSSIDer image now, I see that you're running an open guest network.  That isn't good news unless is intentional.  An open network is an open invitation to anyone to use your bandwidth, and conduct illegal downloads.  Usually a guest network is encrypted to prevent such an occurrence.  The other problem is that running a guest network essentially splits the output power between the two networks.  I only run a guest network if necessary, with encryption, and when not required, I disable it.


Channel 1, which is where you're currently at looks to be the best choice for now.  You have a lot of competition for all of the 2.4 Ghz channels, so, any channel that you use will be a compromise.  


Just for comparison's sake have a look at the 5 Ghz channels with the Acer laptop.  We have an Acer laptop that is about three to four years old that we run off of the 5 Ghz network as the 2.4 Ghz situation around us is pretty crowded.  There are somewhere around 35 to 40 or more 2.4 Ghz networks running nearby, so, pretty well everything we have runs on the 5 Ghz network, and there, we normally see 5 or 6 networks running.  

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

@Datalink - So the guest network was not something I set up and was just automatically set up when I put in the USB stick. It is encrypted though (again, automatically, didn't set that up myself).


Do you know how I can disable it? I didn't see a way to do that immediately.


I'll have to try the Acer later when my husband gets home from work - his laptop is passworded and I don't remember what it is anymore.


But at least according to the HP laptop, there doesn't seem to be anything on 5GHz in our immediate area.

Re: Hitron CGN2 verrrry slow wifi for one laptop only

Call tech support to have it turned off.  I don't know off the top of my head if there is a user interface control for that.  Watch with inSSIDer to ensure that it disappears off of the display.  Then run a couple speed tests to see what turns up. 

Re: Hitron CGN2 verrrry slow wifi for one laptop only

I Plan to Stick Around

@Datalink - I've had the guest network disabled, but it hasn't fixed the weak wifi signal. However, it has changed the graph that inSSIDer gives me - there isn't anything else competing with me on Channel 1 anymore. I'm now getting a Link Score between 45 and 77.


I've got Rogers Tech Support on live chat as well to see if they have any further suggestions. Right now, he says that I have access to the Rocket Wifi modem with 5G capability in my package.


Should I upgrade to that one?
