desktop acting odd on networking connection?

here's the pattern... what do you think is going on

1...all of a sudden started losing connection with "connection unplugged" error message in the taskbar. linksys lne100tx

2... performed a "go back" which is a computer restore program on steroids. i restored to a safe point and my connection was fine.

3...this happened about 3x and each about 3 or 4 days apart. i did a "go back" each time and everything was fine.

4...network connection finally gave out - "go back" did not solve the problem.

5...i switched connection to the onboard intel connection and everything worked again. connection fine at 47mbs.

6...STILL i got the same error unplug message in the taskbar even though i was connected.

as i type right now, the error message has popped up twice in the taskbar. once before, after switching to the onboard networking card, the error message kind of,,,"blinked" ??

so, to sum up..maybe it was the linksys, but i still get the same error message even with the working onboard intel networking connection

anybody have an idea what's going on?
