I recently replaced my old Linksys router with an Airport Extreme Base Station. And as soon as I did, I began to experience hideously slow web browsing, with pages often taking minutes to load. I ran various speedtests, but they were all normal. The problem is browser independent (Safari, Firefox even tried old Camino), and was not fixed by clearing caches, cookies, etc... After searching the forums and reading about other peoples' similar experiences, I disabled ip6 on my computer (MacPro - 10.4.5), but that didn't help. I did a hard reset on the router, and on the cable modem. I updated the firmware on the AEBS. No differences. So I reinstalled my old linksys and everything's back to normal (except the wireless isn't as good and it can't seem to handle video chatting in iChat, which the AEBS does fine, so I want to get the AEBS working). Any other suggestions?
