Hi, I've just committed urtwn(4) to -current. urtwn(4) is a driver for Realtek RTL8188CU/RTL8192CU USB 2.0 802.11b/g/n adapters. It is currently enabled in i386 and amd64 GENERIC kernels. Notice that it does not support the RTL8192SU devices which are different. The adapter requires a firmware which is available as a package here: http://damien.bergamini.free.fr/packages/openbsd/\ urtwn-firmware-1.0.tgz
The driver has been tested with a Hercules HWNUp-150 adapter but it should work with the Edimax EW-7811Un too. Please report if you have such a device. Damien
