Well, from my house and dorm, I'm able to access the internet perfectly. AIM will connect, I can visit any website (albeit I have to refresh a few to get them to load in Safari) and everything is just peachy. But at some friends apartment, I hook my ibook G4 Mac OS X.3.6 up to their LinkSys BEFSR41 router and not only can I not play World of Warcraft (which is why I'm over there), but also I can't access some internet sites. AIM still connects, and I can visit Google and some other sites, but among those that just refuse to load are this one (appleinsider), Yahoo!, MSN.com, and WorldofWarcraft.com/Blizzard.com. I can even do Google searches, but the result websites usually aren't able to load (some of them are, such as the Mac OS Hints forum). The firewall is disabled, and I'm not sure why only some sites will load, and nothing else. I even managed to ping/traceroute Yahoo.com and Worldofwarcraft.com Just to clarify, there were several other Windows computers hooked up to the router which worked perfectly, using DHCP from the router. I've taken the DNS servers from the router's configuration page and even added them to the appropriate place in network settings.
