Please show for when working OK and again for when "internet going out" ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

You are losing your connection to your router. Notice on the second ipconfig it says media disconnected for every network device? This is the equivelent of pulling out the cable for wireless devices. IS your signal strength weak on the network card?

It's even stranger and more complicated then simply disconnecting.

Initially you are connected via "LAN-Express AS IEEE 802.11g PCI-E Adapter" and there is no evidence of an ethernet adapter. When disconnected the wireless has completely disappeared and "Marvell Yukon 88E8039 PCI-E Fast Ethernet
Controller" makes a sudden appearance.

If it were only the wireless disappearing I'd say the wireless adapter is loose or defective. If you can access the card through a cover on the bottom then remove it and carefully and firmly replace it three or four times (to clean the contacts).

But I don't know what to think with the ethernet controller playing hide and seek. Maybe the motherboard is defective?
