I doubt it is ZA causing the problem, I have used it on an adsl for 12 months and never had a problem. True, it can be tricky configuring a firewall but you will find that with all of them, but my personal opinion is ZA is one of the easier ones. Try uninstalling it and reinstall, choose the option to preconfigure for internet access. Also go to the programs section and make sure you have your browser and email client selected to allow access. This may seem a sill question but can you access the internet with no firewall running?
I have been using it successfully with my ADSL connection for over 12 months myself but I have just upgraded to 1Meg and am now experiencing slow downloads. A few people have suggested it could be ZA. I am not totally convinced but as I am not happy updating to v5 anyway, I thought I would take this opportunity to try something new.
outpost is good for another free firewall but its not as user friendly click here
ps. to test if it is zonealarm causing the problem maybe shut down zonealarm temporarly and see if your connection is any better. open zonealarm and click 'overview/preferences' and untick 'load at start up' then restart the computer.
to get ZA starting up again, open it via 'start/all programs' and put the tick back.
My ISP advised to completely uninstall ZA rather than just shut it down which I did. There was no change in the download speed situation though.
I have downloaded Sygate and Kerio and have tried Sygate first. It does take a bit of getting used to after ZA but I intend to give it a fair chance.
However, my main reason for changing was to see if my ADSL connection improved, which it hasn't and as others with my ISP are reporting similar problems it now seems that it is more likely to be a contention issue.
