Wireless network does not work LAN is fine

Running an old HQ laptop with Windows XP. Has a Broadcom wifi adapter.

Yesterday all was fine, I could see 7-8 different wireless networks and connected just fine.
This morning, no networks to be seen. Nada.

Connects fine through LAN.
Other computer works fine on Wifi.
Uninstalled-reinstalled driver.
No conflicts in Devices.
Blue little light to show that Wireless is on works, can turn off and on.
Wireless Zero is on automatic (Services).

:confused

 

150 views.. no ideas..?
I'm wondering if the wireless adapter could be defective, is it an easy swap with one from a different laptop?

 

Refomartted and re-installed Windows XP.
Works now.
