What is MTU
MTU stands for Maximum Transmission Unit. Information flows over the internet to us in small packages. Rather then receiving an entire file (such as an image) all at once, it is split up into smaller pieces and sent to us. MTU defines how large those pieces can be.
The size of a packet of data also includes the header information that comes with it. Smaller packets will transmit more headers along with the data.
For an ethernet connection (a standard network card) the value can range from 68 to 1500. The default value is repported differently accross the internet. Some say 1500, 1480, or other values. These high values seems to cause problems. Changing the value to 1492 may help ressolve some problems (or 1400 if you are using VPN).
Also make sure that your router and all PC’s on your network are setup to the same values.
I’ll be tweaking a few things here and there until I can ressolve my crashing issues.
Oddly enough, the MTU Ping Test gave me max results at 1472. Adding 28 for the MTU header size, that brings me rite up to 1500. Now I’m really confused.
