My macbook stopped connecting to the internet out of the blue. I am still on the same wireless network as the other computers and can share files. However, all other devices still connect fine using the same network. I've gone through the deleting/ recreating the airport in System Preferences and even tried deleting the system configuration folder and restarting. No results. Any ideas?

Yes.

Whew, you don't have anything like PeerGuardian installed?
More Terminal tricks...
dscacheutil -flushcache
host 173.194.33.50
netstat -rn
As a matter of fact, I do have PeerGuardian installed, but it's not been running.

In my research I found hundreds of cases of PeerGuardian being the sole cause of this exact same symptom. Uninstalling it was the only solution I found at all for this problem.
Is it listed in Sys Pref>Accounts>Login Items?
Wow. I had never heard of that happening, but sure enough, that fixed it! Thanks a lot BDAqua. I never would have figured that out otherwise.
Great news Nate, thanks! 🙂
I also have this question but instead of installing PeerGuardian I installed Tor. I have uninstalled it, rebooted, and even reinstalled my iStat widget and it still says on my iStat widget Ext: Unknown.
Connected to Wireless Network, but can't connect to internet
