My CAX80 started acting up
My CAX80 started acting up yesterday as well. No idea what changed but devices on 2.4 Ghz would work fine. Anything on 5 Ghz was sporadic connecting to the internet. Very frustrating when you work from home and have to be on conference calls. I tried several things to resolve the issue, but the only thing that worked was flashing an older firmware version to it. It auto updates every night which is frustrating, but at least I am able to work again.
Once it updated to the latest firmware 5.1.1.8 again over night, I was able to disable the Protectrion Engine and that appears to have resolved my issues.

This was supposed to be a response on another thread and not a new one. LOL Yes a factory reset has been completed since the last fw update. I'm on ch 1 & 48. Armor disabled, no parental controls, etc...
I have tried with smart connect enabled and disabled.
WiFi continues to allow me to connect locally to devices, it just doesn't allow internet access.

Ok, good to hear. NG is aware of the PE issue and is under review. Keep it disabled for now. You'll be fine.
