Acer 5920G + Orange Broadband Problems

I recently purchased the Acer 5920G, and am absolutely loving it at the moment. I currently have Orange broadband (Still with wanadoo supplied equipment) that is connected to my PC wirelessly.
First thing i wanted to do was to get my new laptop up and running online, so i Run the default software "Empowering technology" and clicked on then internet tab. It detected 2 Netowrks, both mine and my Neighbours. I clicked on connect, it promptly asked for my WEP key so i typed it in. Now this is where my problem arises. It indicates that "Connection to the Wireless LAN has Failed" I've tried many times but to no avail, i really want to connect to the internet

Any help would be appreciated

 

try remove the acer enet mangement and use the xp or vista wireless configure

acer enet has issues with connected to some networks

 

Yeah, as andy said that might work. If it doesn't, then i would try to download the updated drivers for your card from intels website here's a link http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=2259

 

First update your WiFi drivers & go to WiFi device properties

# Set your WiFi network search setting to Aggressive(Available under WiFi Properties)

# After that set WiFi transmitting power to 100%

Finally try to connect again
