(SOLVED) MTU 2000 or higher

[HNGamingUK]

Hello,

 

I am having issues when I set my MTU at 2000 or higher.

 

I have checked the specs and my motherboard has Intel® Ethernet Connection I217-V and it supports Jumbo Frames.

 

I can set it to 1900 but not 2000 or more.

 

Thanks,

Connor

Without more information about what you're trying to achieve, I think the only advice would be leave it at 1900.

I'd leave it at the default 1500.

I am trying to improve performance, I am running a Plex server on it.

 

I think I will just leave it at 1900. I will be changing to a Synology unit soon more than likely.

You can't just choose any old MTU and expect your network to continue working. The default is 1500 and if you change it from that figure you must change every device that connects to the same network segment to match. Jumbo frames are far more trouble than they are worth because they are not backwards compatible.

You should see the MTU setting as a "no user servicable part" unless you happen to be a network engineer or reads tcpdump like a native.

 

There are a million ways to get hurt by playing with the MTU.
