Didn't you receive the cd with the drivers on there, There is a wlan driver under the option drivers tab. Have you installed that one. I am guessing you have not had a look in that tab for the other drivers, some you can use others you cant as the items are not actually installed on the laptop but the WLAN is there. I only used the drivers on the cd and had no issues at all with any drivers
forgot to mention what OS have you installed as I am using win7 however if you are using linux as your previous comment seems to suggest you may. Then you may have an issue as apparently the wireless card is incompatible with ubuntu distros, some report changing the card worked
have a look at some of the comments on the ebuyer site at the bottom
