I haev a zydas wireless usb adapter, which runs completely fine in windows. However I've been having all sorts of problems getting it to work in ubuntu, first tried it with the built in driver and got nowhere. Then I tried installing the windows drivers using ndiswrapper which kinda worked, but couldn't get connected at all and in the end uninstalled it all. Now I've installed rewritten zydas drivers which are working mostly, but I'm still having trouble connecting. Every time I start I have to manually enter my essid, access point, rate etc. Sometimes they won't stick and sometimes they do. dhclient almost never works, but occasionally I can get connected through the wireless assistant. But after about 10 minutes that died and couldn't reconnect. Any ideas?

Still no luck. Can see router and everything but can't connect to it or use internet.
