They never get broken. The only problem is that somtimes the user has disconnected the coax to the antenna by misstake when assembling the card to the RRC. if you connect a serial cable to com1 and setup a terminal program like Putty to 38400 baud, 8 bit, 1 stopbit, no parity and no handshake, you can see the debug text showing strenght and channels from the different APs and some other info which are related to the WiFi connection
