CAX30 (Costco) will randomly stop passing traffic for some devices but not all

Thanks for the reply!

Firmware is 1.4.10.8 and all my drivers are up to date.  Only a couple neighbor's with wifi not too close.  From my most distant device and closest to neighbors, I ran a channel scanner and attached the output but could not attach the output. I'm alone on channel 1 but manually changed it to 1 from Auto.  The 5ghz is set at 153 and the next closest ssid is a -30 bd difference from me. Hope that makes sense!

In wireless settings I have Beamforming and MIMO checked, Airtime Fairness is disabled though.  (Change?)

I just read the another thread you're in with iRyan about reserved IPs being an issue - and I do that.  DHCP is 192.168.1.200-250 with a couple things reserved as .100-.102.  Sounds like i need to stop reserving and manually configuring. (at work we call it SDHCP - static dynamic... grumble. anyways!)

90% of the time I'm sitting beside the router when my single connection drops.  If I do default, are there any "features" I should leave alone?

Is there any trick getting by the level 1 ISP support that asks you to reboot when you just need to check correct provisioning/line quality?  I get it - but I think everybody on this site is beyond that 🙂

I hope this attachment is legible. Thank you guruFURRYe38 !
