Details of problem:
For a long time i had a non-wireless network, but having just moved I'm now forced to use a Wi-Fi network as in my new home the modem's a long way from my computer. While on my laptop the network works just fine and it's all stable, on my desktop (for which I bought the Cisco Linksys AE2500 USB) it connects shortly, then, while still connected to the network, the icon on the lower right displays the danger triangle /!\ and gives the message No Network acces (during this my laptop is on without problems). When this happens other nearby networks (which it did detect while briefly connected) are no longer on the list either.
Solutions and measures conducted:
First, I worried it was a problem with the modem or the internet connection itself, but as said, on the laptop it works just fine. Next I thought it might be the Linksys, so I disabled the networkadapter on my laptop and hooked up the linksys there. Worked fine. Tried all different USB slots, did not help. Taking it out and plugging it back in works briefly, but then it switches back off. When I try to disconnect from the network and then reconnect (Im still connected to it, just without internet acces) it gives the unable to... message, and subsequent troubleshooting does reconnect with the following message:
Problem wih wireless adapter or acces point Detected /!\
But it does reconnect... briefly. Then it goes off again.
Recent changes to hardware/software
No recent changes apart from the obvious one: getting a wireless network adapter instead of normal cable.

Edit: It's probably worth note'ing that yesterday, after having the same problems, for a while the connection was stable for a good few hours, but this morning it just tanked again (apparantly without comming back on. I did not do anything different then (just replugging a few times, troubleshooting etc), so I couldnt define anything about that that might have "done it".
