Last night my Linksys WUSB600N stopped connecting to my router (Linksys WRT400N). Over the past week or so the wireless connection would cut out for a minute and then reconnect, which it had never done before, and then yesterday it stopped connecting all together. I'm running Windows 7 Ultimate x64. I have the latest drivers and my router has the latest firmware. Linksys tech support is just a bunch of idiots BTW. Anyway I brought the adapter to work with me today and hooked it up to my laptop and it works just fine. Linksys offered to RMA it but I don't know if anything is even wrong with it. I even reformatted my comp last night (which I was planning to do anyway) and the adapter still doesn't connect. It sees the networks and asks me for my security key but it just fails to connect. Every other computer in my house connects to the router just fine so I'm lost.
