I am using firmware .22 with a CGNM-3552 and am on 500/20 profile but am not getting anywhere close to 500Mbps download. Is this because of the firmware or a neighbourhood issue. These are the results this morning hardwired to modem:

Hi mgamaledin,
Now that you have posted this message, wait a few more minutes and magic will happen 🙂

Also why only using 2 channels for Upload? If I remember correctly i had 3 channels with .22 firmware?
Yes I had 3 Upstream Channels Before so why only 2 now? http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Getting_connected/message-id/335...

Triple_Helix,
Yesterday, I verified a few items for the users including yourself that reported uplink issues. I noticed that your modem was actually connected to a single uplink channel. On your modem it goes from 1 to 2 but it should be 3. I sent this off to one of the CMTS engineer for his feedback and he came back to me this morning that there is indeed an issue but based on the measurements from your modem and your neighbours, he doesn't believe there is an RF issue in your neighborhood that would cause this type of problem.
It is also very unlikely that the firmware caused this issue but it is possible that the problem is caused by a faulty modem. The recommendation from the CMTS engineer is to have your modem replaced as a first step and then take it from there if you are still experiencing problems.

Cr*p as I don't want to exchange it for a used one as mine was new when I got it. But will do tomorrow and let you know the new numbers so I can get the Beta Firmware again.

@RogersDave Well this is odd! I did a Reboot of the Modem and now I have 3 upload channels????

Also Upload speed is not that great:
The firmware 4.5.8.27 is currently in trial phase. Of all the users that were upgraded to this release, a few users reported a degradation in uplink speed. This is being investigated but there is no a obvious fix and will take some time.
In addition, the case of @Triple_Helix is different as his modem is not syncing properly on all uplink channels.
As always, if any participants wants to withdraw from the trial or temporarily return to a previous version, you can always send me a PM. I'll be happy to return your modem to a previous version.
I am also happy to assist with testing (time permiting) if you would like to run tests across versions which may require multiple upgrades/downgrades.

Thanks,

I would hold off in that case. I assume you still can't get more than 15 Mbps even with the 3 channels? This suggest that you have an issue with the firmware.
We haven't identified precisely why certain users are affected while others are not. It could be modem/hardware specific or it could be an incompatibility with some other hardware or configuration.
I am hoping to know more in the next 2 weeks at which point you'll be able to make a decision.
