    Wireless USB on 10.04


    This may be a silly question, but I'm not sure how this works. I've been reading online about USB wireless adapters, so could you use a USB wireless adapter as the wireless card, and connect to my network? I currently have a Gateway desktop that is just sitting around and I want to connect it. It has no network interfaces other than ethernet and dialup(which I can't use). And if you can do this, are there any USB wireless adapters that are known to work well with 10.04, or just Ubuntu is general? Thanks.

    If you get a reply, let me know. I've been trying to get a USB wireless adapter to work for the past two weeks. Lucid Linx says it's connected bit it doesn't see my D-link router or the other three computers.

    USB Wireless-n in Ubuntu 10.04 broke

    I managed to get my usb wireless-n adapter to work in Ubuntu 10.04. Unfortunately, Windows managed to hose the hard drive while I was configuring it so I had reformat and reinstall both WinXP and U10. The USB wireless-n works perfectly under WinXP but nothing happen under U10. The icon in the Panel shows spinning arrows indicating there's a connection but I can't actually get out. I entered the WPA1/2 password using WICD to try to access my network. WICD sees the network plain as day. I get a message the password is bad. I then try using the preshared key in WICD. Same error message. I connect directly to the router from my other PC and verify both the password and preshared key. What I entered under WICD was correct. What gives? What should I try next?

    I have a ralink (rt2070) usb N, and Ubuntu 10.10 recognizes it and works fine. I have had problems in some other distros getting the right driver, but 10.10 works fine.
