Adjusting the MTU size in the FRITZ!Box
The FRITZ!Box does not allow you to adjust the MTU size manually. This is also not necessary because the FRITZ!Box supports the MSS clamping procedure (Maximum Segment Size) that automatically adjusts the size of data packets to the smaller MTU of connected networks. This prevents performance losses due to fragmented or discarded data packets.
Note:The Maximum Transmission Unit (MTU) is the maximum size of user data that can be transferred in a single data packet. The maximum MTU for cable connections is 1500 bytes. The cable provider can reduce the MTU by using additional protocols.
