Ralink wireless lan card not exist

advent 9115 i removed vista and installed xp home and now i have this problem of a black symbol and when i go in to set up i have no wireless options and can only connect via ethernet how can i ressolve thi without cost cheers chris parnham your just not getting any replys, Ralink Wireless LAN Card Not exist, When i got my advent, It used to work (the card), I started playing around with the voice recognition, left it on all the time, so it wud get used to my voice! Was playing music one day, chatting to some friends, didn't pass any heed, looked at the laptop and it said for a split second "Blah blah wireless card uninstalled" but now obviously not!!! Turns out I shudn't have got this shitty model! solution fixed, put all your important stuff on a memory stick and throw the laptop down the stairs, walk into the place you got it, tell them about how "**** happens and collect" (I'm hoping you paid insurance)
