Hello!


I'm  desperately  trying  to get a micronet SP907GK V5 (USB 1.1 WLAN-Stick) to
run under openSuSE 10.3.

lsusb tells me the manufacturer is Realtek rtl8187 so  I  compiled,  installed
and modprobed rtl8187 for the 2.6.22.5 kernel.

The module loads and iwconfig lists wlan0 as wireless device. wmaster0 is also
created. I could not find any info on what wmaster0 is for. Some say it  is  a
hint  for  malfunction of the driver. I did configure the device with Yast and
also by hand (setting essid and key with iwconfig and using dhcpcd or ifconfig
with static local ip) but had no success when pinging the router.

Micronet does not list my device as linux compatible but the support says they
don't have any devices that run under linux although the FAQ  list  a  few.  A
similar  one SP907BB is said to work under linux but it seems not to be on the
market.

Well any help or hint on how to get my device working are very appreciated.

Thanks
Lynx
