Very slow connection 250u

MarcosSilva
I'm Here A Lot

So, I have the 250u internet package and I'm getting really slow connection.

 

Rogers Speed Test says it goes from 10mbps to max 30mbps (wireless)

Wired it was 60mbps

 

Tried in another laptop and got the same 10mbps wireless 

 

I have the CGN3ACSMR.

Re: Very slow connection 250u

i had the same issue wireless with AC Hitron's ... tried two of them... couldn't get past 30 on the 2.4GHZ band... i went back to an original CGN3ROG and i get 90 on ignite 100u using the 2.4GHZ band

 

try the 5GHZ band and then check with tech support for the latest firmware version... you may need an update

 

otherwise swap it for a CGN3ROG if you can and see if that helps

 

your signals are fine by the way

 

another thing... if you have time... have tech support test your signals from their end and ask them to check others in your area, just to make sure its not a network problem... you can try some ping tests and tracert's from your end to see if you have any serious latency or packet loss... ask tech support to do the same as well

You need to separate the wire and wireless issues.  First thing to do is get the modem running properly for wired 250/20.  With Rogers speedboost kicking in you should see peak rates of +300 Mb/s downstream, 21-22 Mb/s upstream.  Your downstream signal levels are higher than normal, they should be down around 0 dBmV, but, where they are at the present time shouldn't be causing problems.  Signal to noise is good and your upstream signal levels are good. Are you in an apartment, condo, highrise etc, etc by any chance.  The fact that your downstream levels are fairly high with normal upstream levels leads me to wonder about where you live.   

1.  Are you connecting directly to the modem via ethernet to a pc or laptop or are you running a router in between?  If you are running a direct connection, the modem should be in Gateway mode.  If you happen to be running a router, the modem should be in Bridge mode.

2.  Can you have a look at the back of the modem and confirm what colour the connected port LED is.  Amber indicates a 1 Gb/s connection rate with the pc or laptop, which is necessary to support rates above 100 Mb/s.  Green indicates a 100 Mb/s rate.

3.  Can you log into the modem and check the software (firmware) that is loaded, as indicated on the first STATUS page that comes up.  It should be version 4.5.8.16.  The previous version, which some modems might still arrive with, is 4.4.8.14.  That version is very problematic for a gaming, VOIP devices, VPNs and latency intolerant applications.

4.  Can you run a wired speedtest at www.speedtest.net using the Toronto Telus server as well and post the results.

5.  Call tech support and ask the CSR to ensure that the modem is provisioned for 250/20 service.  Given your wired test result of 60 Mb/s I wonder if it isn't provisioned for the 60/10 Mb/s internet plan.

6.  For wireless performance, note that any combo modem / router box from any ISP won't be great.  That just seems to be a fact of life no matter which ISP you deal with.  If wifi performance is an important issue for you, you should really consider buying a good third party router and run the modem in Bridge mode.  That is what I and a good many others on the forum do.  The results can be like night and day, depending on what your wifi environment is like.  To look at that environment, you need to load an application such as inSSIDer, which is a wifi monitoring application.  The linked version below is the last freebie version.  Loaded on a dual band laptop, it will allow you to look at the 2.4 and 5 Ghz environment and see what you might be up against in terms of competing networks.  The 2.5 Ghz band can be unusable in some places due to the number of nearby and overlapping networks.  If so, your choice is to shift to the 5 Ghz band which will hopefully be far less crowded, or, buy a good router which will provide much better 2.4 Ghz performance, to the point of being able to operate with your laptops in that crowded environment.

This version of inSSIDer doesn't display the 802.11ac networks running in the 5 Ghz band, so it doesn't present the whole picture, but, there is a newer pay version out now that does, and which runs on a normal 802.11 b/g/n laptop by reading the transmit headers and presenting the 802.11ac networks along with all of the others.  

So, load inSSIDer and have a look at your wifi environment.  When you look at the display, its shown with zero at the top and negative scale below.  You want to see your network as the highest power level network on the display, with the others at or below 40 to 45 dBmW from where you network is sitting.  Anything less than that and you can start to have problems, especially if the other networks are running on the same channel or on an overlapping channel.  The display will show you if there are any channels available with less interference from other modems/routers.  What you see on that display will go a long way to understanding what you are competing with, and hopefully help you determine if the 2.4 Ghz band is usable, or if its crowded to the point where its time to abandon ship and move to the 5 Ghz band.

@Datalink

 

Thanks!

 

So, let's do it:

 

1 - Directly, it is in gateway mode.

 

2 - Green light

 

3 - Version 4.5.8.16

 

4 - Wired, it went up to 89 mbps

 

5 - I will, but when I log into "my rogers" it says 250u plan though

 

6 - I live in a Highrise, I've used inSSIDer before to change the channel to a less busy one. 

 

Tested it wireless just now and got 36 mpbs.

Re: Very slow connection 250u

Ok, you've got one problem to contend with and that is the connection rate with the modem.  That green LED indicates that you will be limited to 100 Mb/s or less with whatever you are connecting to.  Is that a pc or laptop?  As it is, it would appear that the device has a 100 Mb/s port on it, or, possibly the ethernet cable you are using isn't connecting properly, or its only capable of supporting 100 Mb/s.  If you have another Cat 5e or Cat 6 cable around, can you try that for a test?  

 

As for wifi, a similar problem exists with the wifi card.  It may be limited in terms of its performance, possibly due to being a single antenna, single data stream card.

 

Unfortunately, as we have seen before on the forum, upgrading to the 250/20 Mb/s plan exposes the limitations in the connected equipment.  So, it takes some research to look at the specs of the equipment, specifically the wired port controller and wifi card model data.  

 

1.   What are you connecting to?  Can you provide the exact model number for the pc or laptop.

2.  Can you drill down into the Device Manager and have a look at data for the ethernet and wifi cards.  Copy the device model data and paste it into the thread.  That way we can start to look at the specs for the port controller and wifi card.  

 

What you might find unfortunately is that the device(s) that you have on hand are not capable of running higher than 100 mb/s.  For a pc, changing or installing a gigabit controller card will solve the issue.  For a laptop, that is more of a problem.   You could use a USB 3 to gigabit ethernet adapter.  We have a couple of those around the house for times when we want to connect a laptop that doesn't have an ethernet port.  Here is what we have:

There are others around as well:

The wifi can be a challenge, depending on what we figure out.  It might be possible to change the wifi card for a newer, more capable card, but that will depend on what model laptop you have.  @VivienM is the resident expert on that one and can probably advise you on whether or not the laptop will accept a wifi card swap.  Some don't apparently.  

 

If its not possible to change the card, or you don't want to tackle that, you could use a USB dongle, preferably one that will also run 802.11ac.  Don't go cheap, if this is the route that you eventually go, but, you don't have to go ultra expensive either.  I'll have another look at these if this turns out to be the way that you want to proceed.

 

Ok, for now, a little homework is in order.  Let us know what you find.
