tplink wrote Just to make a test, disable the wireless encryption for the 5GHz wifi and keep tracking the status of the 5GHz wifi, checking if it still crashes. Need the test to help locate this...

tplink wrote May I know how long will it take to crash the 5GHz signal in average? After a router reset, it takes a few days, after just a Router reboot, it starts crashing the same day.

tplink wrote When the 5Ghz wireless disconnects, could you see the 5GHz signal on your wireless devices? It just disappears or still exists there but couldn't be connected?Will a reboot (not reset)...

I'm having the same issue with my C3150! It's getting really annoying, and disruptive, they need to release a firmware update to address this. TP-Link, where are you?
