Hi Guys i was just wondering since i have seen so many posts on the CGN3 issues, i myself started having a strange issue the other day. I have unlimited 150Mbit Internet and have 5 laptops and multiple phones connected to the internet
When gaming on my PC, i usually stream movies via shomi, but lately every time i try accessing anything with the other devices while this is happening i am getting loss of data connection. Seems each device is still connected and obtaining ip's and the CGN3 logs show no issues, however this has been happening alot.
Is the current firmware for the CGN3 currently still 18.104.22.168 if so then its weird, i have reset the device and when i do it takes like 30 mins to reconnect, its like its looking for my ethernet, but at night when my PC is asleep its not initializing the Wifi until after its fully connected. But if i am not using wifi the modem continues to restart its setup, like when you pull the plug, like a soft reboot.
Any feedback would be helpful, I know quite alot about the CGN3 but i am thinking its defective.
Your downstream signal levels and signal to noise ratios are good, the upstream are slightly elevated above their normal 36 to 40 dBmV range, but there is nothing in the figures which would indicate any problems due to signal levels. Can you have a look at the following thread and check your modem logs to look for any critical errors, as is shown in the log in that thread, and have a read thru the second paragraph of my response. I've only seen one instance of an issue with a remote device causing problems with a CGN3, but that isn't to say that it can't happen more often. The immediate action that you could take, if its easy to do, is swap the modem at the nearest Rogers store. If that cures the problem, its an easy fix. If it doesn't cure the problem, then my thoughts would be that there is a device which has a bad wifi adapter or ethernet port. And that might not be anything more than a setting adjustment.
Funny thing is its only after being up for about 7-10 days before this starts again. I will try resetting it and then changing config a bit to see.
