Home routers support an option to set the MTU size manually when needed. An appropriate MTU value is important to the proper operation of any network. To change the MTU on a DI series D-Link router, simply follow the steps below: 1. Connect to your router's admin interface. Usually 192.168.0.1. The default username is "admin" (without the quotes) and the default password is blank. 2. The first MTU value is the interface MTU, it’s 1500 bytes by default for Ethernet. The second one is the IP MTU which is also 1500 bytes. Once you get above 1500 bytes your router will start fragmenting the IP packets . Jun 21, 2020 · How to change MTU size in Windows 10.

MTU and TCP MSS settings on router interfaces. The maximum transmission unit (MTU) for the ExpressRoute interface is 1500, which is the typical default MTU for an Ethernet interface on a router. Unless your router has a different MTU by default, there is no need to specify a value on the router interface.

In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer , e.g. Ethernet frame .
