OK, brief description of system. Desktop PC connects to Internet via BT Voyager Router. Laptop uses wireless connection. Daughters Laptop is only a couple of weeks old & connected easily to internet; worked perfectly until yesterday.
My daughter complained that there was no wireless connection available, little icon in system tray has a cross through it. Laptop runs XP Home & she is setup as a limited account. If I login in as administrator it will find the wireless connection & function OK. As far as I know no new software has been loaded, no changes made to any settings. It just stopped.
Had a quick look at the wireless connection settings & they all seem OK.
If I change my daughters login from limited account to admin she still cannot connect to wireless.
Just created a new limited account & that can connect to the wireless network.
Ran the wireless network wizard to create a new connection but this made no difference.

Bit stumped as to what the problem is & how to cure? Any advice gratefully received.

thanks in advance
