T3 and T4 timeouts

[Cricckket]

I am having exact same issues with my Archer modem. Really tired of having to restart all the time its a real issue when you have smart plugs and porch camera that you cant access cuz if network issues. Please fix. Ive seen other posts with same problem. I am using the connection that comcast plugged me into when i was using their modem

What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

[Cricckket]

Sorry where is that info. And i cant seem to log into that number

[Cipperon]

you may have to plug in directly to your modem to access that page. Once it loads it usually will take you straight to the Status page which was what he was requesting above.

[Cricckket]

Ok i will try in a few hours thx
