Good Wireless connection, but not able to browse Internet

Using Ubiquiti Nanostations for a Point to Point, at the end of the Point to Point is connected a Ubiquiti UniFi UAP-OUTDOOR 2x2 MIMO Access Point. When connected wired over this connection no problems Internet browsing. Speed tests are 7-8 MB down and uploads are around 300 - 400 K. When connecting to the wireless access point shows very good signal and connects fast. Browsing the Internet is slow or web pages do not load at all. Even when this is happening can ping like and get reply's. This happens to anyone trying to use the wireless so it is not computer specific.

Anyone have any ideas?

Might be something wrong with MTU since ping works, but web not.

try ping
then ping -f -l 1472 (which sends a packet of 1500bytes) - if that fails, try down to see how small packets you can send.

You might be on to something, I had lowered it on the router down to 1470. On a ping it fragmented until I got down to 1442. This is in an RV Park so I will need to wait and see if the complaints stop. Will post again if problem is resolved.
