Wireless N 5GHz DGND3700 v1

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.
