.19 did not fix the bridge mode issue. I did reset both modem and router.
I don't have the 2.4 issue that affects the speed. Tried all mentioned above no change in speed probably may be due to my speed is just between 100-200mbps even in the old modem
experiencing big ping spikes tonight on .19 but it seems as if upload has been fixed on this firmware, seeing around 40 up right now (2am) , download is still way off the expected areas of 900+ (and nowhere close to what it was on the cgn 3552 which was in the 700 area) , hovering around 475-575 (depending on speedtest.net/rogers/dslreports). Looks like we are heading in the right direction not sure why some like me are experiencing the degraded download though will keep you updated
@RogersDaveTested WIFI on a Nexus 6 and LG G5 and disconnects have been corrected but 5GHZ AC connections are EXTREMELY slow still getting faster uploads than downloads. Also had an issued yesterday where my wired connection slowed to under 10 when tested but a reboot solved that. No .19 here yet.
There was a lot of discussion in this forums over the last 24 hours regarding the impact of 2.4 GHz WiFi on the speeds. This is a known issue on some modems and this is why a week ago in my troubleshooting steps, disabling 2.4 GHz WiFi and/or moving external routers 6 feet away from the modem was part of the list.
For affected modems (which we can generally identify from the network), firmware 188.8.131.52 provides a great improvement in most cases. Now I see that @Alex4161 has that firmware loaded but is still experiencing degraded speeds with 2.4 GHz WiFi enabled and we will therefore investigate further.
Ultimately, we still have a majority of customers using this device that are seeing a vast improvement in speed, jitter and latency. When DOCSIS 3.1 gets deployed, this will get even better. We still have other enhancement to the firmware planned for January (version 184.108.40.206) that should bring improvements to WiFi speeds amongst other fixes.
