only occassionally is it just the phone. but last night every device on my network lost internet at the same time, yet wi-fi still connected, all LEDs solid indicating no ISP issues outwardly.

 

i reboot it, and everything is good for 24 hours usually, then problems start again. it's like the wi-fi router internally looses touch with the cable modem portion.

debating on just buying seperate modem and router now.

 

so right now, i looked at the "advanced", Internet port, Connection status, and every field is 0.0.0.0, and lease obtained/expired fields all blank. this is what i feel the problem is since i do seem to have an issue every day ~ 24 hours from a reboot...

 

why are these fields blank?

Do you have a screen snip of the cable connections page and the modem logs? 

If the wifi is connected but showing "connected, no internet" and you don't have an address from the ISP, then it could be a modem/isp/line issue.

    snip attached, what from the logs would be relevant or helpful? i attached one entry that's concerning to me since it recurs every 15 minutes or so...

     

    thanks for your help!
