Hello. I have a problem with my ASUS K52JT laptop. My configuration is Intel Core i3 M380 2.53 Ghz, 4gb RAM (3.86 usable) DDR3, Windows 7 Ultimate 64bit Service Pack 1, AMD Radeom 6370m 1gb.

Very often, during the normal use of the system, my laptop looses the LAN internet connection all of a sudden (it says Unidentified network). If enable WiFi my internet connection gets back, and the laptop recognizes again the LAN connection along with the wireless one (if I turn off WiFi I loose the connection again, with the Unidentified network prompt). From that point the system starts freezing every 20-30 seconds for about 2-3 seconds, until restarted.

I have thoroughly verified the network equipment, the router and the cable, ran an antivirus scan that turned out OK and even reinstalled Windows (the problem first occured about a month ago, shortly before formatting the system, and reappeared 2-3 days ago).

What could it be?
