How to Speed up Your Home Network by Changing the MTU Size

In this video, we talk about MTU is, why you should consider changing the MTU size to get the most out of your home network, and I'll walk you through how to actually get it changed.

Command to test the packet size:

Command to see all of the network interfaces and the current MTU size:
netsh interface ipv4 show subinterfaces

Command to change the MTU size:
(Replace "Ethernet" with your interface name and "1428" with the best MTU size you found)
netsh int ipv4 set subinterface “Ethernet” mtu=1428 store=persistent

I had a lot of jitter on my network and this helped smooth it out a lot! Thanks for the useful info!

[TheLegoTrainStation]

Interesting stuff! Just started using my Honor Router 3 today so messing around. The only Wifi 6 device around is my gf's phone and she isn't even here cuz lockdown..
I found this via your website. Ironically the highest stable value I could get was 1472, which when you add 28 takes me back to the router's default 1500! But fun either way.

[broderickfall]

Simple, concise, organized and indexed, and to the point.
You, sir, have got yourself a new subscriber

[soumyadebnath]

Ayy man thanks you were such a helpfull person and easy to understand. mine was 1344 and 28 added it got to 1372. Thanks man.

[Sam-kxjc]

Great video. Straight to the point. I found my best MTU setting was 1472. Plus 28 equals the nice and round 1500 figure

[SnappingTurtle]

Virgin Media 1GB fiber in UK. 1452 was the highest I could go before fragmentation. Added 28, 1480 is my new MTU. It was 1500 by default. Cheers big man.

[GregiiFlieger]

Nice job. I like the fast and straightforward charging through the topic. If people think that your going too fast, they should just watch again! Thanks and cheers!

[okkerz]

hi mate great video but when i put netsh int ipv4 set subinterface "Ethernet" mtu=1492 store=persistent instead of it replying OK its says element not found can you please help

[TheUncleshady]

lol I was hyped up! Got it down to 1472. Added 28. Got 1500. Router defaults to 1500. Anyways....

[Xbaharat]

But I have an issue when I run the command that changes the MTU it says: Element not found

[MjedOP]

The filename, directory name, or volume label syntax is incorrect. this is what i get when i set the mtu. what is the problem ? please help me

[CSAFMedia]

When I performed this step 5:06 the displayed MTU value 1500 was higher than my ping test optimum MTU plus 28 value, 1498. So really no need for a change?

[Mecrom]

how does the mtu size get distributed? both the sender and receiver need to have the same mtu, correct? So how do they know the mtu of eachother? dhcp?

[jakenotjake]

so when testing ping at my 1500 mtu(already at 1500), it wont work, highest i can get is 1478. then when changing you said to add 28, which puts it back to 1500. i dont get how that works

[Eloign]

What do you do if it says operation not permitted?

[rednajma]

New subscriber here. Glad to see your video 'coz I couldn't find a way to change MTU via my modem's interface. Very helpful!

[diasandreas]

Ive tried my mtu, it still pinging even at 1200. I used ethernet connection, what should i do then??

[harifidyr]

It helped me a lot, others tutorials dont show me how to find my local network router name. Thank you very much and nice job.

[leadiususa]
