Linda, I guess that's all you needed together with everything else!!! Its seems to be an issue with Zone Alarms firewall - I stopped using it some years ago as I found too many little unhappinesses with other programs fussing about it.
Firewalls can really cause havoc - quite often they are the problem with problematic internet connections and there isn't a perfect one out there!!
I've had all the recent updates and so far no issues with wireless or wired Internet connections.
I use Sygate Personal Firewall which is also free and seems stable with most programs.
How's the wireless problem doing BTW???
