My wifi connection can not search signal !

My Laptop is Dell studio XPS 1340 , origin oparating system is Windows Vista Home Premium 64bits , and my wifi card is Dell Wireless 1515 Wireless N-Adapter.
I had upgrade operating system to Windows 7 Professional . I had download the lastest driver from Dell's Website and installed to it , the first time i run it , everything is ok ( my wifi too ) .
But 2or 3 month later , my wifi can not detect any access point ( in my house and my office ) ( but when i use another laptop , it connect to wifi very easy ).
I had try re-install windows 7 again , and re-install driver , then wifi be came good again , but same time later its still not detect any more .

Somebody known what problem with my laptop or my operating system ? And then how can i fix it for next time .

Thanks you anyway !

 

Uninstall your driver from device manager and try this updated Atheros Chipset driver

Updated Atheros drivers are hard to find

Choose the driver on the top
v9.1.0.100

@tomcat57 : thanks you for reply , i had download and re-install new driver but it still not detect .

 

Try changing the chanel in you router.Especially if it is set to ''auto" change it into something else.

 

could also update your firmware. reinstall your chipset drivers (back-up disc) and hopefully that will get you back on your feet.

another thing as everyone always says. check your router settings!
