All network connections drop

[WinchesterStoke]

Hi, I have a Dell Inspiron M5030 running 7 Home Premium. The last few days it's developed a problem where it drops all connectivity (other devices don't have a problem connecting to the router over wifi) randomly (<5 mins, maybe a couple of hours). I get the cross over the darkened wifi bars.

It tells me that there are no network connections. (there are)
Troubleshoot brings it back sometimes (1 in 5 I'd guess) - it tells me that there is a problem with the wireless adaptor.

It looks like both the wifi and Ethernet connections are down.

The wifi is Atheros AR9285. Ethernet is Atheros AR8152.

Any ideas please?

have you checked to make sure your drivers are all up to date?

Yes. I have checked and they are latest drivers.

It seems strange that both Ethernet and Wifi go down together?

Any ideas please? The laptop worked without a problem for a few days but now has started playing up and won't connect?

Thanks
