FS#2558 - Linksys 3200ACM drops link speed from 800 Mbs to 19.5 Mbs

Linksys 3200ACM drops link speed from 800 Mbs to 19.5 Mbs in about 5 minutes. If I disconnect the WiFi connection from the phone I am unable to reconnect. I have to reboot Openwrt.

Radio1 and radio2 are disabled. FYI, stock FW has no issues with WiFi.

I was able to recover by removing the config using the following commands:

rm -f /etc/config/wireless
wifi config > /etc/config/wireless

I have isolated it down to the channel. If I set the channel to "Auto" it fails to work. If leave the channel set to "36(5180)" it works.
