Mel--

We have a laptop upstairs running off this router on wifi (no cable)

I just don't like typing on it. It doesn't have my files on it either.

My husband has a new HP from work laptop that runs VPN which is
another network. It was what started this whole thing. He brought it home
Dec 6th and it crashed my desktop. His old one that was replaced due to
its small harddrive ran fine with my desktop...never crashed, and it has the same VPN program on it..downloaded from his old harddrive in fact.

So we thought that was the issue...but apparently there is more than one
thing happening. Perhaps a rotating IP address issue. ( I found some things about it on Google, but it said a router can separate the IP addresses. Which ours did previously).

He is plugging into the router now, so I am testing the wifi laptop upstairs.
We'll see if I last.
