What is MTU?

MTU stands for Maximum Transmission Unit. It is the largest data packet transmitted by a network device. When one device communicates with another over the internet, the data packets travel via multiple devices along the way. On the off chance if a device in the data path makes use of a lower maximum transmission unit setting as compared to other devices, the data packets should be fragmented to accommodate the device with the least MTU.

Netgear WiFi routers come with the default MTU size. However, you can change it through IP address.
