MTU Setting: MTU (Maximum Transfer Unit) defines the largest data packet size you can transmit in one go across a network. The AOL network runs at an MTU of 1450. Many routers have inbuilt auto-configurations where the hardware identifies that the AOL traffic has an MTU of 1450 and dynamically adjusts. Alternatively you may have to manually change the MTU setting on the modem router.
If the router hardware does not have this facility, the MTU setting can manually be changed on the computer to 1450.
You can change the MTU setting on your computer by using DrTCP. This is a free software utility that is a shortcut to editing your registry. This is available at: click here.
MRU Setting: MRU (Maximum Routing Unit) is required by some modem routers and should be set to the same value as the MTU of 1450.
MSS Setting: MSS (Maximum Segment Size) is required by some modem routers and dynamically adjusts the packet size to fit the MTU. It should be set to 1410.
Got this off the AOL website...In order to check your settings you will need to access your router / modem's admin screen. Do you know how?
