My girlfriend just had her computer repaired and since she has gotten it back she is not able to connect to our wireless network. I've tried many different things to get it working and none have worked.
When she got the computer back I noticed a new program that I had never seen before on her computer, it was Intel ProSet / Wireless. We brought it back to the place that repaired it and they were able to connect to their wireless network through her computer using this program, but it absolutely will not connect to our network. We've reset the router and tried all the common fixes.
I've also tried disabling Intel ProSet and connecting through the Windows wireless manager, but that didn't work. It can't be our network because my internet is working fine.
Any suggestions or possible fixes to this problem? She's running Windows XP. If any more information is needed in order to determine the problem please let me know.
