Orange Livebox - check WEP/WPA 1st

Setup an Orange Livebox for a client - was actually quite impressed with the turn-around from Orange for setting the broadband up (ordered 6 days previous, and it was already live when i started setting the Livebox up).
Wired connection worked straight away, but trying to get the wireless side was not as straight forward as i thought it was going to be....
Wireless signal picked up, entered the encryption key as provided on the bottom of the box, and it jus sat there 'Acquiring network address' and 'Waiting for the network to be ready' (and yes i had pressed the '1' button on the back!)
Went into the web setup for the router (admin, admin) and copied and pasted the WEP code straight into the wireless connection properties - still no joy. The MAC address for the laptop was showing as a wireless device, but it just wasn't getting an IP address from the Livebox.
To cut a long story short, i thought it may have been a problem with the Livebox, as the '1' button didn't flash as it described in the manual, so i called Orange support.
After trying many things on the phone (much of the time being about 3 steps ahead of the helpdesk) it seems that the problem was with the wireless encryption being used - the Livebox was set to use WEP and WPA encryption; i changed this to WPA only, and the laptop connected straight away.
If only Orange had suggested this first, would have saved on a 30 minute phone call (and me faffing around for way longer than i was supposed to be there)
