Model Number PCG-71313M

Thanks for reading.

I recently did a clean install of Windows 7 Home Premium (64-bit) on my Vaio laptop. The problem is that although I can install all the other drivers, I simply cannot find the driver for the WLAN device on the laptop. I found the other drivers from the support page for my model:

http://support.vaio.sony.eu/computing/vaio/downloads/preinstalled/index.aspx?l=en_GB&m=VPCEB3J1E_BQ

but the drivers provided for WLAN do not seem to work.

I've been trying to update them in device manager using the update driver option. Asking windows 7 to search the internet, I'm temporarily connected by ethernet, yields no results, and manually pointing the search to the downloaded driver folders from the Vaio support page also leads Windows to say no suitable drivers have been found.

Any help much appreciated. I've noticed a few people across Google mention they've had similar problems with the WLAN driver provided on the support page. If this is the case, could somebody let me know the maker and model of the WLAN card so I can try to source an alternative? At the moment I haven't been able to find any information on this.

Thanks.
