Best protection w/o Zone Alarm for my wireless

Unfortunately, I removed my Zone Alarm from my desktop and laptop because it was interfering with the sharing of the printer. I had the free ZA version and after many configurations and online help , i gave up.

So, how can I get some protection on my wireless? I added a password to both computers. I know that XP has a firewire built in its system. And I heard on some techtv shows that the router has protection built In.

What the best way to go with this for my modest home wireless network?

 

Firstly, are you sure you removed it???
Had several problems with clients PC's where zonealarm was 'removed' but still blocked ports, found the best way was to reinstall, set everything to 'off' or 'low' then uninstall. If you're struggling with zonealarm, then outpost or similar out of the 'free' stable will probably give you a seizure.
Cough up some dosh and get norton internet security, not sure, (cos I use hardware firewalls) but it may be available as a free evaluation download.
Don't bother with the XP firewall, its a pile o' $hite, depending on your router, it may give you the best protection anyway (providing you have antivirus and run both adaware & spybot s&d regularly)
