With good signal levels and acceptable noise levels, the 3552 will match the 4582 for speeds if you're running gigabit service. If you're running 250/20 or less then they will absolutely be equal. The difference is that the CODA-4582 does not suffer from the high latency that the 3552 or CGN3 series modem do. Those modems are a Puma 6MG modem which has that problem. The 4582 is a Puma 7 modem, which doesn't have the latency issue. However, at the present time as you have noted, there are issues with its introduction into service. So, personal opinion, unless you're having issues with latency in gaming, stick with the 3552 for maybe another month. By then another firmware version or two will have rolled out for the 4582.
@RogersDave Thanks for taking a look at my issue. i have swaped the modem to the modem with black dot
Modem also got the latest .23 pushed.
I have Factory Reset the Modem
Connected Directly to Modem even though its set in Bridge.
My download speed for some reason is not passing 400mbps ( I was constantly getting ~800 with old CODA on pre .19 FW. Issue started happening from .20 on wards ..
Whats going on .. missing my CGN now

Ok.. So i have narrowed down the issue and found out my speeds are back to 900Mbps down / 40mbps UP between 1.30AM - 8.30AM everyday !!!
So when i run Speed test at 1.30AM - 8.30AM every day, my speeds are back to 900mbps/40mbps up while rest of the hours its stuck at 400Mbps ..
Is this due to Network Congestion ? My area is still on DOCSIS 3.0
That seems like a congestion issue since off peak hours you get good speed. To me that rules out your PC, Gateway, Settings, etc. I would call Tech Support and explain to them how during the day speeds are slow, and off peak hours everything is fast.
Thanks !!! Case Created - C119705438 If any Tech person can expediate this to Network team it will be great please .. Paying 1Gbps but stuck at 400mbps .. still willing to be on beta trail ..
I do have gigabit service. Thanks for your reply. Ill wait another few weeks or a month and then hopefully everything is better.
Is anyone else experiencing random modem reboots (non firmware update) after or around midnight?
it just happened twice within the hour (EST) today. Firmware is on .19

Count me in amongst the multitude of people who have experienced issues with this modem.
On top of it rebooting twice in the last 35 minutes (12:05am EST and 12:35am EST), I experience consistent slow downs at peak hours, to the point where I can't do multiple things with my connection at once.
Despite having a Gigabit connection, when I run speed tests, the most I've ever seen was 850 down and about 30 up. More likely (especially during peak hours), it's in the 400mb down/15 up range.
Even worse, when I run Speedtests on sites not affiliated with Rogers (I don't trust them to provide accurate results) i'm getting numbers below 100mbps.
Running Firmware 188.8.131.52, and the event log is full of "No Ranging Response" errors (among others).

Same thing happened to me. Modem just reboots twice today. A lot of No Ranging Response received - T3 time-out on my logs.
And after disconnections and reboots

Alright so we have multiple users who confirmed that their modems are rebooting randomly (at least once) from 12AM-1AM. The time when the modems reboot also coincides when maintenance is done on the network- not sure if it relates to the modems rebooting, but it is my suspiscion.
