If you check the thread you will see multiple report of stability issue.
The most critical I am experiencing also are:
a) Sometime on connect the interface cannot deliver traffic to the lan bridge, reconnect required
b) Loss of lan traffic for 1-2 minutes every now and then, restores automatically
c) After some days of operation unable to connect to 5Ghz radio, reboot required
d) Sporadic packet loss/speed drop
