Wireless Networking Cutting Out

Fujitsu / Amilo 2515

Specs: Windows Vista Home Premium
I have had a Fujitsu Amilo laptop for just under a year and have generally had no real problems.

In the last week my wireless networking has been cutting out after a period of continued use; often a re-start will resolve the problem for a little while but the problem always returns.

The wireless connection status drops to "Connected with limited access" and other wireless networks in the vicinity disappear - attempting to diagnose/repair the connection does nothing of any use.

Disabling/enabling the connection then finds no wireless networks with the error "Windows cannot find any networks.". The router is fine and other computers can connect.

When the connection has cut out, attempting to update the driver or disable the adaptor (an internal Intel card) freezes.

It feels a little like an overheating problem (starting from cold usually gives me a longer connected period) but after having run speedfan there seems to be little or no correlation to the wireless cutting out/higher temperatures.

I have tried updating the driver when I am able to, and it has not resolved the issue. I have tried using an external USB adaptor when the internal adaptor had died and it didn't appear to be recognised.

Any ideas?

A recent discovery is that I can access each of the tabs on the wireless adaptor driver properties, except the power management - when I try to view that, the window crashes.
