Trying to help my friend with her work XP laptop, which recently stopped seeing any wireless SSIDs except the SSID 'hpsetup' (presumably from a wireless-enabled HP printer).
Relevant information:
The laptop is a Lenovo T500 (Centrino 2 chipset) with XP SP3.
The network adapter is Intel WiFi Link 5300 AGN (built-in).
The latest version (13.5) of the Intel drivers only are installed, not the Intel config software, so XP is using the Wireless Zero-Config manager.
The wireless router is a NetGear WGR614 v7 with 802.11b/g. The SSID is broadcasting, and all the other laptops in the house can see and connect to it.
On the laptop, I have tried repairing the network connection, disabling power management, turning off 802.11a & n radio, and more... but it didn't help.
Some of the wireless settings are managed by Group Policy from her office (I get the "At least one of your changes was not applied successfully to your wireless configuration" message). It is enforced to connect to "Access point (infrastructure) networks only".
The real kicker is that my laptop does not an SSID named 'hpsetup' here, but it can see several broadcasted SSIDs including the one we want, while my friend's laptop doesn't see any SSID except 'hpsetup'.
Any suggestions?
