EasyMTU is a free utility that optimizes your TCP/IP settings for your dial-up adapter (MaxMTU, MaxMSS, DefaultTTL, and more). Windows has default settings for TCP/IP that are not optimal for your modem, with packet sizes that result in a slowed-down Internet connection. These settings are stored in the registry and can be modified, only it is difficult to find the right key to modify. EasyMTU searches for the TCP/IP protocol binded to your dial-up adapter and changes only these settings, so other elements of your registry (like your network adapter) are unaltered
