4. With clean boot, try to apply the hotfixes contained in the subsequent KB articles:

Hello

I have lately the same problem. I changed my NAS from Thecus N5200PRO to N7700Pro. Copying to this new NAS causes this error. As soon as round about 40MB/s are copied the wireless connection aborts and never came back. I have to unplug the router and reboot it to get it working again.

Info:
Windows Vista Home Premium 32 bit (Intel WiFi 5100 AGN - latest driver v13)
Router -> LinkSys WRT54G (Wireless G - 54 MBit Connection).

Observation:
Even due to the fact that the router not supports 802.11n some moments before the wireless network vanishes the connection speed is shown as 300 Mbits connection.
