Hello everybody,

I have an USB wireless card with chip Zydas 1211rw using module zd1211rw. It used to run perfectly in Ubuntu 7.10, but I've upgraded to 8.04 and it doesn't connect or show any wireless network. It also doesn't connect booting with desktop CD or upgrading from 7.10 to 8.04 without any CD.

But if I start 8.04 version with 7.10 kernel (2.6.22) card connects perfectly, including with WAP encryption. It also connect if I boot with 7.10 desktop CD.

I think it is a problem with driver or module zd1211rw in conjunction with new kernel.

Typing "dmesg | grep zd" I get:

[ 58.667458] zd1211rw 2-2.4:1.0: eth0
