I have a Sony Vaio VPCEH15EN laptop & the OS is Windows 7 home basic. I have a wifi router which is of TPLINK.

The wifi won't connect to my laptop but it works fine on my mobile..it would only start working when I use the ethernet cable. I never had this problem before. I have tried everything ..I also tried the winsockfix.bat but all my efforts have gone in vain..I just don't know if the wifi router is faulty or the modem of my ISP...Please help me solve this problem.

Best Regards,
Om

the mac of the wi-fi should be on the wireless permit list of the router to connect to it .

The Router is NOT faulty as it works with another wi-fi device just fine.

*I'm a little confused. Was THAT exact laptop working with wi-fi already, or did you mean a different computer was working?

The main problems are hardware vs software:
1) HARDWARE:
If your wi-fi in the laptop was defective then you can buy a USB wi-fi adapter.

2) SOFTWARE:
There are multiple areas to have issues here.

When you run the Wi-Fi setup what exactly is the problem?

I haven't run the wifi set up...it worked before on the same laptop. I haven't tried any other laptop. Will it work fine with the USB wifi adapter?

Thanks,
