Thats a bad idea, anyone can setup a Rogue AP with your WLAN SID in
your Network and collect the authentication trials
of the users. Server Certificate is a MUST ! Don't disable the checks.
Don't talk to strangers.

It's seems strange to me, that a router reboot causes the
Freeradius-Servercert to fail. Debugoutput ?
