WiFi drops and after it is back on, broadcast is not working #364

Closed dolohow closed 4 years ago

dolohow commented 5 years ago

I am using OpenWrt 18.06.3, r7798-97ae9e0ccb and when device is powered on, after about 15 minutes, WiFi drops and when it is back on, broadcast is not working. Means I cannot reach other devices in the network.

I have the same problem OpenWrt 18.06.4 r7808-ef686b7292 Linksys WRT32X

Known issues with using DFS channels. I recommend staying off of them to avoid this problem.

[ 1220.534290] ieee80211 phy0: radar detected by firmware <<<<< You will only see this in the log if a DFS channel is selected and Radar is detected. DFS detection is poor, meaning spurious signals other than radar can trigger the channel being abandoned.

Known issues with using DFS channels. I recommend staying off of them to avoid this problem. That worked, but it is a workaround. Closing...

Thanks
