Hi!
I can confirm this issue. I have a METAL that disconnects all clients, and has it’s wlan interface completely stop working. A scan wont even show any other APs.
I have 2 metal and both are doing the same.
Mikrotik can not have a solution and can not respond .
U can see it in this topic too : http://forum.mikrotik.com/t/problem-with-mount-point/94/1
Im thinking to change it to R2SHPN with rb411gl, but after that I do not know whether that is good Innovate.
