I just reformatted a Sony Vaio for my gf that I am going to sell, but I am having some trouble with the built in wireless card. When ever you try to search for networks it does not find any. It doesn't even try to search, it just says no networks found.
I have reinstalled the drivers several times for the card. The card is enabled, switched on and appears to be working in device manager. Wireless Zero Config is running and enabled etc. I also tried using the adapter in safe mode and I tried using net stumbler and it still is not working

Any ideas? I know there are some computer geniuses on here

 

Also it was starting doing this right before I reformatted it, which is leading me to believe it could be a hardware problem not a software problem

 

sell it as-is


go to "systems" then the "hardware" tab and see if everything looks fine.

 

I'm assuming this is a laptop so it might just be a problem with a loose connection. If you can access the Wifi card check and see if the antennae cables are attached properly to the card. You should have wifi wires running throughout the laptop that pick up the signal much like the radio antennae for cars are run throughout the car or on the windshield.

 

Bad/defective wifi card?

Similar symptoms on a few HP laptops I've worked on. They all had bad wifi cards.

 

I'm sure you've already done this, but this is the only advice I offer:

I sometimes have similar problems that you have described, usually they are fixed by right clicking the green LAN icon.



Then hitting "show main dialogue" will bring up this:



Deselect the desired frequency, then apply settings.

Reselect the desired frequency, then apply settings.


Again, probably doesn't help you at all, but figured I'd throw something out there.
