MTU or maximum transmission unit (MTU) is a protocol that determines what size data packets should be.
Well its seems that Popular WiFi (or Wireless) Routers or LAN Routers have the ability to set a certain value for MTU.
What does MTU effect? Well it can effect such as Login Problems with Windows Live Messenger, X-BOX Login Problems, PS-Network Login Issues.
My recommendation is to experiment with the MTU value, but my recommended value is either 1492 or 1500.
