I have an old Sony Vaio laptop, it does not have internal wireless card so I use a PCMCIA wireless card in it. I just installed windows XP Pro with SP2. The laptop came with XP Home before SP1.

Anyway… I can’t see any wireless networks and I have 3 of them in my room.

I have put in another hard drive into the unit and restored the computer to FACTORY settings and the PCMCIA wireless card works fine. (This laptop is too old to have built in wireless so no on/off switch here)
I have installed all the drivers for the laptop and there are no issues in device manager.
I know my network adapter is Enabled so no issues there.
I have tried restarting zero wireless config service. No luck there.
I’ve reinstalled the wireless driver. No luck

I’m wondering I have the wireless working on one hard drive and not working on another. I’ve upgraded them both to SP2, the only difference is one is home and one is pro, and the home is factory settings. HOWEVER I’ve uninstalled all programs on the factory drive hoping there was EXTRA software that would cause it to stop working and I could just reinstall that.

The wireless appears to be working but I cannot view any. It says there are no wireless networks available.

Is there anything I can copy from the factory drive?
Any other ideas of what could be wrong here?
You need to tell use what wireless card yo0u are using.
But why didn't you just stick with eh XP Home and do the SP upgrades?
What version of XP pro do your have? Is it for the Sony?
