I'm new to Linux. I currently have installed ubuntu 12.10. I had a previous problem with my wireless card (see url to see previous problem : How to enable wireless in a Fujitsu LH532?). It now shows Connect to hidden network and create new wireless network but now unfortunately it simply cannot find any wireless connections. I did have a very thorough look around about this problem such as wait a little longer since sometimes it cannot load all the wireless connections available that quickly. My wifi is a hidden network and I have used the connect to hidden network feature but it keeps asking for my wep key which has been checked 4 times (I counted) and it still seems to not work; It keeps asking for the WEP key. I did try both WEP 40/128-bit key and WPA & WPA2 since previously on my windows it worked; My family later decided to use WEP. I only have a quick fix using a usb wireless stick and I wish to have a more solid fix.

Thanks
