I just installed ubuntu 9.04 on my PC. But I can not make my Wireless USB work!
I try to use ndiswrapper, download and install ndiswrapper(windows wireless manager). And I used a window driver in ndiswrapper. Nothing error prompts. The driver is IOGear GWU623 windows XP 32bit driver. I was told in other forum that would be OK for WN821N in other guy's platform. And I also tried TP Link driver, actually it prompts the driver is not valid.
But when I use "ndiswrapper -l" to see the result, it just prompts:
arusb_lh : driver installed
I can not find "device (0CF3:1002) present" message. But I am sure that the wireless adapter is connected.
And I use "lsusb", the adapter is in the USB list.
How could I make it work? Anyone could help?
