Hi,

Can anybody help me with the wireless D-link on Ralink?

Thank you very much in advance!

My D-link PCI wireless card have been working perfectly on Ubuntu 8.10 for a few days, but suddenly crashed - one day the connection was lost, and the Network Tool could not connect to my hidden wireless network.
And next day, the small connection icon (a computer display) in the lower right corner of the desktop dissapeared.

I tried sudo ifconfig wlan0 up, but had no results.

My win computers continue working perfectly with wlan.
