Is this an X1030AP or X1030US?
If I were a suspicious person (which I am), I would ask why it takes "a few hours" for a software problem to appear. This reeks of hardware and overheating. I don't think it's software.
OID_Blah are calls to the NDIS driver. This is the interface between the operating system and the wireless card. The call was successful, but the card did not respond. Therefore, the most likely culprit is the wireless card.
My guess(tm) is that you're overheating something. It might be the wireless card, but I can't tell from here. The first thing to do is get some canned air and blow out the fan intake and exhaust area from the usual accumulation of dirt and dust.
Remove the wireless card. That's easy as it's accessible through a door on the bottom of the unit. Be VERY careful with the two u-FL antenna connectors. They break easily. What you are looking for is obvious damage, dirt, and improper seating in the connector. I could not determine the make and model, but such wireless cards are commonly available on eBay. Just buy or borrow a spare and see if it fixes the problem. Also, try running the unit with the cover off the wireless Mini-PCI slot to temporarily improve its cooling. If that "fixes" the problem, it's an overheated card. It's probably NOT the card that's causing the heating, but whatever is directly above the card (i.e. CPU).
If you're mechanically declined, disassemble the unit. Instructions are here:
Also, I suggest you download and run Memtest86 ver 3.2:
