Hi,
I've had some problems getting the WiFi to stay stable on the WRT1200AC, so I tried OpenWRT.
Problem description:
There's 2 radios on the device, an AC (radio0) and BG/N (radio1).
I'm having trouble getting radio0 to stay up. Whether it's up or not is random. Just after setting OpenWRT up initially, both radios ran fine, but after a while, radio0 stops working.
Running LuCI 15.05-142-gb6330a1 Release (git-15.363.78009-956be55) / OpenWrt Chaos Calmer 15.05.1
What I've Tried:
* Rebooting the device helps in maybe 1 on 4 tries.
* Even though the radio is marked as enabled, and I've typed "wifi radio0 up" in the console, I get this message in the frontend: "Wireless is disabled or not associated"
Documentation
When tailing the log, I get this when running "wifi radio0 up":
