Weak wifi

 

Does anyone ever had this issue .... I have a roger 150 plan and I'm only getting 23 mb  throughout the house had the tech swap out three more modems even the new white hi torn one same thing the tech thinks that there might be interference in that room,the modem is on the main floor in the middle of the main floor and I can stand in the room the modem is and all I get is the same 23mb ??? I suggested trying a 25 foot cat 6 Ethernet cable and put the modem in the living room  kitchen and even upstairs ,I'm 25 feet away from the room the modem was and still 23 my no difference. I bought asus ac1900 dual band router bridged my Rogers ignite router turned off the ignite antennas and nothing changed I even took the 25 foot Ethernet plugged it into the ignite modem side and plugged it into the asus router and tried it in the kitchen living room an upstairs and it didn't make a difference I even swapped the asus router for a new one and exactly the same thing my house is 1800 sq ft really don't know what else to do I even unplugged everything near by any one else having this kind of issue.??


I'm assuming the slow speeds are only over WiFi? A computer hardwired using ethernet lan cable will give you full 150mb/s speed? If so try this:

 

For troubleshooting I would reset the Rogers Modem to Factory Defaults, use a pen tip or similar to press and hold the reset button on the back of the modem for 10 seconds then release. Once the modem boots up plug a computer using the LAN cable into the modem, turn the computer on and open a web browser, you should be greeted by the Rogers quick setup page. Enter a password and name your WiFi network. Whatever password you use will be used for WiFi and to log into the modem. Once that is all done log in to the modem goto wireless settings and do this:

for 2.4Ghz and 5Ghz:

Security: WPA 2 using AES Encryption

disable WPS, and UpNp

 

2.4Ghz: 20mhz bandwith, wireless channel 1, 6, or 11, don't use any other channel

5Ghz: 80mhz channel width, Channel 149+, don't use the lower channels

 

How old is your house? older houses using plaster and different material for construction are terrible for WiFi

Re: slow wifi

@Mike1255 if you're going to use a router, please ensure that the modem is running in Bridge mode instead of Gateway mode.  In Bridge mode, the modem acts as a modem only, so you need a router behind it, running in full router mode.  To change the modem's operating mode, log into the modem using 102.168.0.1 or 192.168.100.1 if the modem is still in gateway mode and you have a pc or laptop connected directly to the modem.  Navigate to the BASIC .... GATEWAY FUNCTION tab, and disable the Residential Gateway Function.  Save the change and the modem will reboot into Bridge mode.  While the modem is rebooting, power cycle the router.   From this point you will need to be connected to the router.  

 

When you are connected to the router, you can log into the modem by using 192.168.100.1 which will reach the modem thru the router.  You can log into the modem to check the DOCSIS power levels for example or change the operating mode of the modem back to Gateway mode by reenabling the Residential Gateway Function.  The modem will reboot back into Gateway mode with the previous settings intact.  If you were to run a Factory reset while the modem is in Bridge mode, it will reboot into Gateway modem with the settings back at their default values.  

 

I'm going to send you a list for your Asus router that you can follow to set it up and with additional instructions to check your wifi environment for competing wifi modems and routers.  If you're trying to use a 2.4 Ghz network, its very possible that you live in a very crowded neighborhood, in terms of 2.4 Ghz channel usage.  If thats the case, even a very good wifi router will have a hard time in an environment like that.  It also depends to a degree on the wifi encryption settings which are part of the list headed your way.  5Ghz usually isn't terrible to operate in, however, its possible, in some neighborhoods to expect those channels to be occupied as well.  You will only know when you've had a chance to check out the channels that are in use.  

 

You will see a number overlaid on your avatar at the upper right hand side of the page when you are logged into the forum.  Follow that avatar link down to your profile and drill down into the message page for the incoming message.  You can simply hit the respond button to forward any questions to me, or you can post further questions in the forum.  

 

1.  First step is to review the various settings in the Asus router.  Set/change those as required and reboot the router when all is said and done. 

 

2.  Then check out the wifi environment and determine what the best operating channels might be, if there are any at all.  You might find that the 2.4 Ghz band is a write-off if its too crowded.   If so, then it will be time to kick as much as possible up into the 5 Ghz band.

Re: slow wifi

My guess would be wifi encryption and bandwidth settings, and channel assignment which you will be able to determine with a wifi monitoring application as indicated in the list that I sent. 

 

Now, if you haven't seen that laptop run anything higher in terms of wifi data rates, there is also the issue of the wifi adapter and whether its running one antenna or two.  We might have to look at the adapter specs to see whats up.   If you drill down into the device manager, down to the network adapters, copy the entire wifi adapter model data as shown in the device manager and post it so we can check the specs.  Unfortunately we keep finding laptops, some of them brand new, well designed, except for one item, a cheap single antenna wifi adapter installed by the manufacturer.  Not saying that's the issue here, just bringing up the possibility as we've seen it happen all too often Smiley Sad

Re: slow wifi

I just upgraded my internet package from 100u to the 500u and got the coda-4582 modem with it. before I was getting around 150dl on 2.4gh and 170 on the 5g.

but since upgrading my 2.4ghz is only getting between 20 and 50 dl the 5g works great as getting over 500 dl.

my computer is only around 25 ft away so distance should not be a issue.

problem is  we have several computers as wife has hers and etc and  mine is only one with 5g.

anyone have any ideas on how to improve the 2.4 ghz speed as  tried changing channels and that didn't work.

Re: slow wifi

@slagheap can you check/set the following 2.4 Ghz wifi parameters:

 

Wireless Mode: 802.11 n 
Channel Bandwidth: 20/40 Mhz, although, for test puposes you could set this to 20 Mhz. In a crowded wifi environment, I would set this for 20 Mhz. 
Wireless channel: AUTO or, to an open channel if one existed, or to the channel that offers the least interference from neighboring routers and modems as seen with a wifi monitoring application listed below.
WPS Enabled: OFF
Security Mode: WPA-Personal
Auth Mode: WPA2-PSK
Encrypt Mode: AES only

 

Save the setting and ensure that the Encrypt Mode stays on AES only. If it changes on its own to TKIP/AES, change it back to AES only and save the setting again. TKIP is no longer secure and in addition can cause the wifi data rates to cap at 54 Mb/s if WPA - TKIP is selected for the encryption mode.  This is done in order to maintain backwards compatibility with older devices.  So, any modem or router in use today should be set for WPA-2 and AES for secure encryption and high throughput data rates.  Here's a notice from Intel that covers the subject:

 

https://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000006697.html

 

More recently, the Wifi Alliance outlawed standalone TKIP settings for encryption, although manufacturers are currently ok to use a TKIP/AES setting.  Selecting TKIP in any form however can result in the modem or router dropping down from 802.11n rates to 802.11g rates, which are capped at 54 Mb/s.  Manufacturers are not necessarily clear on that in their instructions, leaving it up to the consumer to figure it out the hard way.  Here's the reference from the Wifi Alliance:

 

https://www.wi-fi.org/downloads-public/Wi-Fi_Alliance_Technical_Note_TKIP_v1.0.pdf/17196

 

 

Check/set the following 5 Ghz wifi parameters:

 

Wireless Mode: 802.11 a/n/ac mixed
Channel Bandwidth: 80 Mhz, although, for test puposes you could set this to 40 Mhz
Wireless channel: 149 to 165
WPS Enabled: OFF
Security Mode: WPA-Personal
Auth Mode: WPA2-PSK
Encrypt Mode: AES only

 

Once again, save the setting and ensure that the Encrypt Mode stays on AES only. If it changes on its own to TKIP/AES, change it back to AES only and save the setting again.

 

Reboot the modem if you had to make any changes, ADMIN ..... DEVICE RESET .... Reboot.

 

In addition to those changes, please look at your wifi environment using one of the following applications:

That's the last freebie version of inSSIDer and at this point in time is getting a little old. Its fine for 2.4 Ghz application and does work for 802.11n 5 Ghz networks. It does display 802.11ac networks but not as well as it should. This has become a licensed application now for $20 US and works very well for both frequency bands, 2.4 and 5 Ghz.

 

The other applications are fine for 802.11ac. Acrylic is graphical, WifiInfoView is text only.  The latest version of WifiInfoView now has a data column showing the Utilization % of the networks that it detects and the number of devices on the network.  If you right click on the data area to bring up the column selections, you can deselect columns from the display and move any column up or down in terms of the display order.  


What you want to do is determine what channels in the 2.4 Ghz band and in the 5Ghz 149 to 165 range are occupied and if so, which offers the least competition in terms of signal level for any given channel. If you can find a channel or channel range in that group that is not occupied, that will be the best choice to set in the modem.

 

 There is a also Wi-Fi Site Survey function in the modem located in ADMIN .... DIAGNOSTICS that displays the following data:

 

Channel ID SSID BSSID Security Signal(%) W-MODE EXTCH NT WPS

 

That survey works very well in comparison to a typical wifi laptop or desktop due to the three antenna used for the 2.4 Ghz networks and the 4 antenna used for the 5 Ghz networks.  The display isn't terribly user friendly, but, you can copy the data and dump it into something like MS Excel to get a better overall view of it.

Re: slow wifi

Hello,

 

I've been with Rogers for a while and I've been relatively satisfied with the wifi. However recently i've noticed that my wifi signal is quite slow. I have the plan (not sure the name) that should give me 100mg download. When my desktop is hooked up via Ethernet I am getting that speed, however my wifi speed is somewhere in the area of 25-35mg. That seems like an extreme drop off, does it not?

I've had Roger techs at my house and they've suspected that I change the router since i am getting the speed to my home when i use the ethernet. I have an older Airport Express so i decided it was time for a change.

 

Tonight i tried a new router. I bought an D link 859 with 1750AC capabilities. After taking a while to get it going it seems there is no noticeable difference in wifi speeds. I've done multiple tests around my home with both routers and there really is no real advantage to the new modem. The question is....why not?!

 

I've called Rogers and they've offered me the new CODA 4582 which i pick up tomorrow. The question is...is this new modem superior to the older Rocket Modem? Will it help with the wifi drop off?

 

Any help would be greatly appreciated as I'm trying to find a solution to the weak wifi signal.  The same speeds with upgraded router has me baffled....

Re: slow wifi

@deechezaray are you running a 2.4 or 5 Ghz network or both?  Most likely, the answer to your problem, especially if its a 2.4 Ghz network, is the growth in the number of nearby users running 2.4 and/or 5 Ghz networks.  Changing modems and routers will most likely have a very minimal effect on what you see for results.  Any other wifi network that is running nearby could in theory prevent your network from running at its highest rate, and for those networks that can't be deciphered by your modem, router or remote devices, that is considered as background noise.   There are two issues afoot, the issue of utilization of any one given channel, and in the shift in the number of error correction bits in a wifi transmission due to the background noise.  As the channel utilization goes up, with a larger number of users, each transmitting device has less time allowed for transmit puposes over a given period of time, therefore your max data rate will slow down.  The higher the background noise, the higher the number of error correction bits in a transmission, where those bits may have previously been used for data transmission in a low noise environment.  The more noise that is present, the harder it is to run a network, to the point where it might become all but impossible. 

 

At some point users may have to come to a conclusion in terms of using the 2.4 Ghz band.  I have somewhere above forty 2.4 Ghz modems and routers running nearby, so, the 2.4 Ghz band is pretty hopeless.  Solution .... shift everything up to the 5 Ghz band where possible, and even with that I'm fighting with both of my neighbors for channel space.  The end result is that my 5 Ghz network still runs at a respectible rate, but, not as fast as it should, given the low power differential between my network and my neighbors network, as seen on a wifi monitoring application.   Only way to resolve that would be to use high gain antenna on my RT-AC68U which would be good for the main floor of the house, but no good for the upstairs, or, use multiple wifi access points around the house to keep the transmitter to device distances to a minimum.  That is food for thought.....

 

Ok, so, what to do.  First is to check the wifi encryption settings to ensure that the modem or router will run as fast as it can, then check the wifi environment to determine if there are better channels to use:

 

With that in mind, check/set the following 2.4 Ghz wifi parameters:

Wireless Mode:  802.11 n
Channel Bandwidth:  20/40 Mhz, although, for test puposes you could set this to 20 Mhz.  In a crowded wifi environment, I would set this for 20 Mhz.  
Wireless channel:  AUTO or, to an open channel if one existed, or to the channel that offers the least interference from neighboring routers and modems
WPS Enabled:  OFF
Security Mode:  WPA-Personal
Auth Mode:  WPA2-PSK
Encrypt Mode:  AES only

Note that TKIP is no longer secure for encryption purposes and should not be used in a TKIP only, or combo AES/TKIP setting.  On top of that TKIP is not compatible with 802.11n and will force the modem or router to operate at 802.11g rates maximum, which is 54 Mb/s.

Check/set the following 5 Ghz wifi parameters:

Wireless Mode:  802.11 a/n/ac mixed
Channel Bandwidth:  80 Mhz, although, for test puposes you could set this to 40 Mhz
Wireless channel:  149 to 165
WPS Enabled:  OFF
Security Mode:  WPA-Personal
Auth Mode:  WPA2-PSK
Encrypt Mode:  AES only

Reboot the modem or router if you had to make any changes.


Then look at your wifi environment using one of the following applications:


http://www.techspot.com/downloads/5936-inssider.html

https://www.acrylicwifi.com/en/wlan-software/wlan-scanner-acrylic-wifi-free/

http://www.nirsoft.net/utils/wifi_information_view.html

For Android

https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en


Thats the last freebie version of inSSIDer and at this point in time is getting a little old.  Its fine for 2.4 Ghz application and does work for 802.11n 5 Ghz networks.  It does display 802.11ac networks but not as well as it should.  This has become a licenced application now for $20 US and works very well for both frequency bands, 2.4 and 5 Ghz.  

The other applications are fine for 802.11ac.  Acrylic is graphical, WifiInfoView is text only.  WifiInfoView has a number of displays available.  I believe there listed under the View or Options top menu selection.  There is a Channel Summery view that allows you do determine how many wifi modems and routers are running on any one given channel.  In the selection of data items that can be seen, there is also a utilization selection that can be displayed.  The combination of the Channel Summery and Utilization column will give you a good idea as to the % of time that any one given channel is occupied.  Ideally you would be running on a channel where you are alone and have full use of the channel.  Unfortunately, that is very difficult, so, probably the best you can do is select the channel with the least number of users on it and with the least number of users on adjacent channels, which cut down on the available time utilization of your selected channel as well as increase the background noise. 

 

Ok, have a look at the wifi environment and set the 2.4 Ghz  channel and the 5 Ghz channel (in the 149 to 161 range) to the best possible choice and see how this turns out.  Please let us know what you find.  You can take a screen capture and post the image if you need any assistance.  Please be sure to delete your MAC address from that image prior to posting it.

Re: slow wifi

@deechezaray

I can vouch for everything said by @Datalink. When we first switched over to the CGN3ACSMR on the 100/10 plan, we had the exact same issue. We were getting speeds of 130/10 using an ethernet connection but only 30/10 using wifi. After contacting rogers we switched to the 5 Ghz network for wifi, which brought our speeds up to 60/10 using wifi. Then I came across a post from @Datalink going over in detail what my settings should be. After following his recommendations and changing my settings for both 2.4 and 5 Ghz, my wifi speeds, still using the 5 Ghz network, now match the speeds I get using an ethernet connection. In particular, changing the channel bandwidth on the 5 Ghz network from the the default 20 to 80 did the trick.  Unfortunately, rogers tech support told me nothing about changing my settings. Thankfully, people like @Datalink are on here and the help they provide is invaluable.
