Having problems connecting to a non-encrypted wireless network that everyone else is able to connect to? I just recently had this problem and found out that my firewall was corrupt. So, I uninstalled it and reinstalled it and was good to go!

It’s a bug in Windows XP Service Pack 2.

I do not suggest that you install the Service Pack 2 update to Windows XP just yet. Seems like Bill jumped the gun on this one. I installed it on my laptop, and it slowed it down a bit. Even though it is now available via Windows Update, hold off a bit. Check back here for updates.

UPDATE: Some have reported success with SP2. So, you’ll just have to download and install it and see how things go. If it won’t work for you, just go to START>CONTROL PANEL>ADD/REMOVE PROGRAMS>and remove Windows SP 2 (a.k.a. Windows Service Pack 2).

If you feel you might have some Trojan Horses on your computer, or if your Anti-Virus software says you do, then download, install, and run these two programs separately.
