no wifi with ralink rt2870 after kernel panic and reboot


Hi all,

After having my usb wifi adapters working fine for some time, they stopped working and I can not get network connectivity.


Some one else was using my box and they reported seeing a kernel panic and then rebooted the box. Now there is no connectivity through the wifi interfaces.

I have seen the kernel panics related to this driver before, but usually a reboot has no ill effect.

Thoughts or suggestions?

Code:

Hi,

What's the output for 'ifconfig -a'?

Thanks for the response.

I went ahead and compiled the latest driver and installed that module into the kernel. The problem resolved itself.
