I will also test the cable idea. What would results either way means Dalecoy?
Roughly:
If it doesn't re-start, then the problem is likely with the WLIP, and you can work on resolving that.
If it
does re-start, then the problem is likely with the network (or how it fails, or how it restarts), and there's not much you can do without the help of the network folks.
Note: I have no personal experience with the WLIP, so I am
assuming that it will "normally" reconnect if a "normal" network fails and comes back. I would really like to have somebody here confirm that's the usual behavior of the WLIP.
