hi, after you have reloaded the module (or rebooted) can you 'sudo ifconfig wlan0 up' ?
Yes. After couple of restarts and changing CMOS battery, my wlan0 interface powered up.
But facing a new problem now. With my wired connection enabled (eth0) and static ip and gateway assigned, i can successfully browse net. But after I disconnect the wire, the wlan0 gets IP from router by DHCP and I can also ping the router. But I cannot ping the Internet like 188.8.131.52 etc. How to resolve this issue?
