I have been running a CGN3 in bridge mode for a number of years now without any issues. Solid connections and no outtages -- last week, my internet went out, and i determined that my router was not reciving an IP address from the CGN3 -- after many reboots of both the modem and the router, and many resets of the router, i felt the router was broken --
i reset the CGN3 to router mode and this worked -- although its a little flakey and unstable (speed flucuations and wifi drops).
I purchased a new router this weekend, and reset the modem to bridgemode -- and found that it is again not issueing an ipaddress to the router.
As this is a brand new router with the same issue -- could this be a modem/bridgemode problem? Should i replace my modem or just deal with it?
Solved! Solved! Go to Solution.
Swapping the modem is a good idea. Before you do that, can you log into the modem, navigate to the STATUS.... DOCSIS WAN page, copy the downstream and upstream tables and paste them into the thread. Those are the cable signal levels and signal to noise ratios which might be worth looking at, just to be sure that there isn't some cable problem that is the real cause of the problems you are having.
Here i my details...
|Port ID||Frequency (MHz)||Modulation||Signal strength (dBmV)||Signal noise ratio (dB)||Channel ID|
|Port ID||Frequency (MHz)||BandWidth||Modulation Type||Signal Strength (dBmV)||Channel ID|
Yes when i am in default factory reset mode it works -- but the wireless is unstable.
Your signal levels aren't terribly bad, the upstream is creeping up from its normal 36 to 40 dBmV range, but those levels as a whole shouldn't be causing problems. Is the router the only device connected to the modem with the modem in Bridge mode, and then everything else connects to the router? What router did you purchase and what wifi networks do you normally use, 2.4 or 5 Ghz or both? With a new router, I would run a reset of the modem, and then kick it back into Bridge mode, and then run a reset of the router which should cause it to pick up an IP address after the reboot.
