Re: CODA-4582 - Open Issues for Investigation

At what point does a company just look at costs to fix this issue rather then move to a solution that is working. I personally have been dealing with a celluar issue since "May 9th 2016" almost a year later with no resolve and have this internet issue as well. 


The amount of money and time invested in this is mind boggling that it happens and is allowed. Want to know why we pay so much is because of the money and resources wasted trying to fix something that should have never been released to the public.


This is the classic case of trying to be the "first kid on the block" to have the fastest speeds or the newest hardware but in the end its the customer that has to beta test and accept sub par services.

Re: CODA-4582 - Open Issues for Investigation

I've been facing several issues like this for weeks now. I'm very frustrated at having to reboot the modem once or twice every day, and never getting anywhere even close to full speeds.

@Telek Does your Modem have a Black Dot near the power cord on the back? also can you login to the modem and post the signal levels from the "DOCSIS WAN" Page. Lastly any idea what firmware version you are running?

Re: CODA-4582 - Open Issues for Investigation

Hi @gp-se


I appreciate the request, however I've been around the block on this one.


I've had nothing but instability ever since it was installed. I've replaced the modem 3 times, and it's always the same.


When I first had the service installed a few weeks ago, the first modem (which was black-dot) was garbage. Completely erratic speeds all over the place, frequently completely dropped out. I replaced the modem, and it was better, for a day or two.  First speed test on the new modem had 940/52 speed and I was thrilled!


The the other problems started.


Within about an hour or two, the speed drops down to ~240/20-50. Within about 12 hours after that, it drops down to less than 1mbit down, but will stay at 20-50 mbit upstream.  Neither I nor tech support can even complete a speed test, and the only remedy is to reboot. Once I left it for 2 days like this, and it never recovered.


It doesn't matter if I'm hardwired or wireless. Doesn't matter if bridged or gateway mode. In gateway I have all wifi turned off anyway, as I have my own AC3200U access point.


I've spent more than 12 hours in total now on tech support calls through various levels of support agents. I'm infuriated that the tickets get closed within 12-24hr with "problem resolved", even though the problem clearly still exists even at the moment when the ticket is closed.  There are enough people online complaining about the Rogers Docsis 3.1 rollout that there is obviously a systemic problem. Closing my tickets with "problem resolved" is a massive insult. This is what is frustrating me the most.


I'm highly technical and am understanding that this is "bleeding edge", but having to reboot the modem twice a day, combined with network support closing my tickets, is driving me up the wall.


Note that none of the modems have had a black dot by the power cord, but they all have the black dot on the box that the modem came in. I was told by tech support that this is the same thing.

Re: CODA-4582 - Open Issues for Investigation

@Telek i would suggest calling Rogers and demand to get a tech out to replace your CODA with the cgnm 3552 otherwise threaten to walk.
Im using it and can say its head and shoulders above the CODA even when bridged behind a old Netgear R6300v2.
My speeds dipped for a few days so i packed it up and went to trade it in for a CODA and i actually lucked out because Rogers systems were down and they couldn't add new equipment to accounts.
When i got home i set it back up and my speeds are great again.

Re: CODA-4582 - Open Issues for Investigation

I tried that already. They told me that, pretty much, all of the 3552 modems have been yanked. No store within 50km of me has one, and the techs don't carry them anymore.

Re: CODA-4582 - Open Issues for Investigation

@Telek thats a shame Rogers pulled the only somewhat stable modem from their network. Ive read on other fourms people have had decent speeds disabling the 2.4 network and just running 5g. It might be a temporary fix . Good luck

Re: CODA-4582 - Open Issues for Investigation

Doesn't matter, I get the same problem in bridged mode and gateway mode with all wifi disabled.

Re: CODA-4582 - Open Issues for Investigation

Hello Community,


As I mentioned earlier this week, Intel is working with Hitron and CASA to resolve the slowly degrading speed issue. They have made some headway and provided me a new firmware today.


Now, I must warn all of you this is completely fresh off the press and this firmware did not undergo any internal testing yet.


This firmware is exactly the same as with a change in some internal Intel settings. In fact, after I load this firmware, the GUI will still display version If you are not experiencing this issue, there is no point in loading this firmware yet.


If anybody wants to receive this firmware (maximum 5 participants today while we perform some testing), please reply below. You must already be a firmware trial program participant. Otherwise, I won’t be able to upgrade your modem.
