CAX80 problems

When you buy one of these at this price point, there's a certain expectation that it will just work. set it up once and pretty much forget about it.

That has NOT been the case for me as pretty much on a daily basis, one or all of my Wi-Fi devices will report "Connected, no internet". i log into the router admin, it says ISP cable connection is good, all LED's solid, so what's up? Sometimes it's almost like clockwork, 24 hours after a modem power cycle, things stop working again.

most of the time it is just my Android phone(PixelXL), it'll be the only device not working. i have reset network settings in the phone, rebooted phone Cycle Wi-fi, switch between 2.4 and 5GHz.... nothing. only thing that fixes it is rebooting the modem, which makes no sense when every other device connected at the time is working fine.

i "feel" like there's some DNS lease issue because most times those fields are all zeros, and it should be populated. Clicking renew or release lease does nothing.

i am on Cox in San DIego, and this device is on their compatibility list, but i think should be removed.

going to try a factory reset on the router, already updated router FW ... past my 30 days for return so stuck with this paperweight.

i might go back to the C7800, but switched to this new fancy CAX80 because the other was a monster! so big!

thanks for any help or advice, i'm at my whit's end with this CAX80.
