Thanks for all the suggestions!!
I still have not figured out what the problem was.... WAS, yes, because after a "system restore" everything worked as before! Since the computer is quite new, I reset it to the first restore point, and I only had to reset and re-install a few things.
I have NOT run any Windows updates yet, because I think that might cause the problem. When I have more time, I will install the updates one by one and try to find out which one causes the problem.
Since my hardware setup is still the same (same router, etc), I don't think that's where the problem is.
As soon as I find which windows update causes the problem, I will post it...
