We have a network with multiple AP's (the AP's are all MT equipment), and multiple clients connected to each AP using PPPoE. On only one of our AP's have we seen a strange issue : A few, but not all, customers cannot connect to certain websites (like Yahoo, our local newspaper website, etc.). MSN usually works, and most other websites load just fine. The customers are using MT equipment. We have tried switching out the equipment with other MT equipment (to rule out faulty equipment), but that didn't work. Also, some customers are still working just fine using MT equipment on that same AP. The only sure fix is using Ubiquiti client equipment! That always clears the issue completely! Why would this be happening? Could it be an MTU problem? OR a mangle rule that need to be adjusted? Any ideas or thoughts on the matter please post.

can you post the configuration? are you use the last version?
