    EW-7711UTn connection problems (Ubuntu 10.04.1 LTS)

    Just started using Ubuntu tonight, but I'm having problem getting my Edimax EW-7711UTn to work (I'm stuck with using the ethernet cable for now). The light flashes on it and it picks up wireless networks, but when I'm connecting to them, I put in the key, it tries to connect, but the wireless key window pops up again and again and again. I've looked up other threads about this, but none of the suggested methods have worked for me (I've checked to see if it's compatible, apparently it isn't, but people seem to have got it working before...) I'm using a Toshiba Satellite M40 laptop.
