I have not had gigbit speeds in months. My avg is around 300 Mbps and get up to 600 Mbps. Glad to see I am not the only one who is having this issue.

Getting 1175 Mbps on my Hitron CODA-4582, tested via Hurricane Electric in California.
Looks like Rogers is deploying 32 DOCSIS channels for everyone (32×37 = 1184 Mbps), so with the proper network setup you should always be seeing >1Gbps.
There's a constant ~10ms ping to the very first hop though, which probably can't be easily improved without ditching the coaxial network.

Hi,
I just got "upgraded" to the gigabit plan on Saturday. I was on the 100 MB plan and was getting consistent speeds of 100 MB or above in the speed boost zone.
Now with the gigabit plan, I am getting 200 MB sometimes but still around 100 MB for the most part. I understand signal degradation, wireless, blah blah... but I expect atleast 500-600 MBs when I am paying for a gigabit plan.

@jason121212, if you're now on the gig plan, you should be using the white CODA-4582 modem which has two additional sections in the signal level tab. Those are for the OFDM channels, of which, only the downstream portion is active. Not that it matters at this point, but, for future purposes, can you post the entire downstream and upstream levels?
On to the problem at hand and the ongoing "signal degradation, wireless, blah blah...." Your downstream signal levels are terrible, no doubt about it. They should be at 0 dBmV, not sitting down around -12/14 dBmV. Your signal to noise levels are also low, they should be in the 36 to 40 dB range. The upstream are ok, which is more than unusual. Normally as the downstream levels drop due to signal degradation associated with cable aging and weathering, the modem pushes up the upstream levels to maintain communications with the Cable Modem Termination System (CMTS). So, to see the downstream as bad as it is, and the upstream within reason is strange. Don't know what's going on but you need a technician to check out the cabling and connectors.
Call tech support and ask the CSR to run a signal check on the modem. That check should fail automatically and you should see a tech at your home within the next few days, as arranged between the tech and yourself.
Edit: As I indicated earlier, I expect that you would be using the CODA-4582. That modem would be running on DOCSIS 3.1 on the downstream side, and if so, given the low signal levels for the DOCSIS 3.0 channels, I expect the signal levels for the DOCSIS 3.1 channel to be equally bad. There are some customers who are experiencing low data rates with DOCSIS 3.1 running. You might be one of them, but at the present time, I expect that's due to the existing signal conditions. I would expect that data rate to drastically improve when the signal levels return to their normal range.

Looks fine? 100 MB/s is 800 Mbps. 500 MB/s would be 4Gbps.

lol i meant mbps you know that

I was assuming mb/s 🙂 Fwiw, it is possible to see high data rates with very low signal levels, but, you would need to have much better signal to noise ratios to get away with it. Your signal levels and signal to noise ratios definitely aren't where they should be. Hopefully its a simple cable/connector replacement. Underground cabling, if that is what you have to your home might require a temporary above ground cable until a dig permit and bury crew are available.

Called Rogers tech, he was looking into the issue. Pretty much quoted what was listed in the thread and he said that it. Tech will be coming in this week to fix the issue. The area is not affected so it looks like its just my house.
Here is hoping for a quick resolution leading to quicker speeds

@jason121212 when its all taken care of, can you repost the signal levels again, just to see where they ended up.
