My router recently died, and thus we had to install a new router... upon which zone alarm doesn't recognize the network and blocks all internet access. (yes, I have already confirmed that it's zone alarm's fault by shutting it down, and then everything works perfectly)
Yesterday it decided to spontaneously work with zone alarm on, after I'd fiddled with zone alarm a bit, but apparantly that was just a bug, because today I was back at everything not working.
This has been a recurring problem for me, through all versions of zone alarm from 3.5, and not limited to the free edition. I can not find a static mentioning of this problem, even though most people I know experience the same thing.
Operating System:Windows XP Pro
Product Name:ZoneAlarm (Free)
