In the last days I am having some trouble running 5GHz 802.11n with this device and last version of OpenWRT. It turn out that b43 open source driver can’t work in N mode, so I switched to the proprietary WL broadcom driver. However, it cause my router to crash after a client connect to it.
I’m working on it.

You can check if your interface is connected to an AP with
iw wlan0 link

SSID: blabla freq: 2432 RX: 196892 bytes (1278 packets) TX: 19107 bytes (125 packets) signal: -35 dBm tx bitrate: 57.8 MBit/s MCS 5 short GI bss flags: short-preamble short-slot-time dtim period: 0 beacon int: 100
