Vaio Wifi card stops after a few hours

[LiliSanFrancisco]

Hello,

I have a Sony Vaio SVS1312J3EW laptop. Everything works great for a few hours.

However, after a few hours, the wifi card stops. I can restart it by right-clicking on the wifi try icon, and chose 'Repair problems', which reinitilizes the wifi card.

Any idea on how to fix that permanently ?

Thanks

Lili

Lili have you installed the Wireless LAN update that's available on your Vaios support site http://www.sony.co.uk/support/en/product/SVS1312J3EW/updates
