ok having followed the guide on this site to finding my optimum mtu settings it turns out that mine is 1472. any higher and the packets are defragmented. so 1472. when i go to my routers manual it says that the mtu is automatically set at 1500 and so when i went to manual setup to check it is indeed set to 1500.
now i just want some reassurance that changing this isnt going to affect my connection fort the worse, as im not sure what im doing here........is it really as simple as just entering the 1472 and clicking save then reboot?
