Just recently, my E3100 disconnects/stops it's 5 GHz wireless completely about an hr after restarting it. 2.4 GHz works just fine, but 5 GHz randomly dies. I keep seeing this in the logs:
[WIFI.6][ADV] SON-[5G-HIGH]STA([[MAC ADRESS]]) RSSI=-90, RSSI LOW! Finding any other AP for choice...
After that, it transferred all devices from 5 GHz to 2.5 GHz. Any Help?
