Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Good afternoon Community,

 

We have been extremely busy in the last few days working with our vendor to characterize this issue, identify the root cause and work on bringing a workaround into play.

 

I was able to pull logs from all the CODA-4582 currently in use by our customers over the week-end. With these logs, we were able to identify a trend and a potential root cause.

 

For the customers affected, by slow speeds would it be possible to try the following workarounds. These are valid in both bridge and gateway mode.

 

  1. For devices or computer hardwired in the modem, avoid using Ethernet port 1 unless absolutely necessary. Connect any computer or router in ports 2, 3 or 4
  2. If your modem is operating in gateway mode, disable the 2.4 GHz wireless from the GUI
  3. If your modem is operating in bridge mode, make sure to place your WiFi router at least 1.8 metres (6 feet) away from the modem
  4. Make sure to place any WiFi device such as routers, repeaters, access points at least 1.8 metres (6 feet) away from the modem

 

We fully understand that the above are not permanent fixes and are working on making the appropriate corrections via software. Having some feedback from customers on the effectiveness of these workarounds would however help us move forward quicker.

 

Once the above workarounds are implemented, make sure as a last step to reboot your modem.

 

When reporting your speeds, please try to put in the same message the confirmation that you have implemented these workarounds, the average speeds you were getting before and the new speeds (I'm sorry, there are too many of you reporting speeds and it gets hard for me to track improvement or degradation).

 

The above might not be the solution for everybody but it will certainly help some of you with serious speed degradation problems.

 

Dave

@RogersDave 

Judging by your post you guys have a suspecision that there is some RF interference from 2.4 GHZ devices, something not shieled well in the modem? As well as my first report about port 1 speeds being much slower then port 4 might have been accurate i could reproduce it multiple times liek clock work the dy i reported it, But I couldnt reproduce it the next day... 

 

Interesting, I will get my gear onto Port 4 instead when i get home and my AP is already 6 feet away from my modem so no worries there.

@RogersDave not everybody yet has the new modem so what's going on with the cgn3acsmr when is the new firmware going to start being rolled out I'm still getting slower upload since .27 firmware and it's been over 2 months now and still no solution on this

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Will these changes help us that are getting extremely slow speeds? I was getting decent speeds, however this morning I reset my modem and now my speeds are terrible. I'm getting 2-3mb/s max, when I login to the modem my LOG is full of Sync Errors. I know this isn't a hardware issue, because this started this morning after a factory reset. I tried another factory reset and numerous reboots but still getting a DOCSIS LOG full of SYNC Errors, and unusable internet speeds.

 

*EDIT* I disabled 2.4Ghz, ran a speed test and had normal/good speeds again!

I then re-enabled 2.4Ghz once again, but this time set the channel width the 20mhz only, I once again have full speed. So perhaps people with extremly slow speeds should try changing 2.4Ghz to 20mhz only channel width and see if that helps. I also checked my DOCSIS log and so far no Sync Errors after making the changes to 2.4Ghz band.

@RogersDave for #3 - A) Is this only for WiFi enabled routers?

Or

B) Do you mean, don't have any WiFi devices (routers, access points, repeaters, etc.) within 6' of the device?

Or

C) Do you mean, use at least a 6' Ethernet cable to connect your personal router, whether it does WiFi or not (which means, don't use the included Ethernet cable).

I'll update my post but you are right, it should have been more along the lines of "place any WiFi device (routers, access points, repeaters) at least 6' away from the modem".

There are 2 completely different issues but yes we have seen some modems experiencing abnormally high error rates on some DOCSIS channels even though the signal was perfectly normal and the SNR was well above the threshold.

 

For the switch, I believe there are cases where autonegociation fails and the port falls back to 100 Mbps (green light instead of amber). It seems to be more frequent on port 1.

lethalsniper,

 

I do not have an update on this as of yet. As soon as I receive the firmware, I will post an update on this forums and in the 2nd reply of this thread.
