This DOES appear to be effective. Please redirect people to this thread.
Please, post results. Let us know how this works!

To do this on a Windows PC(Windows 7, Windows Vista):
Run CMD; Start>All Programs>Accessories>Command Prompt, right click to run as administrator
Type the command;

netsh interface ipv4 set subinterface "Local Area Connection" mtu=900 store=persistent

or

netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=900 store=persistent

To reset this, re-type the line that worked for you and replace the "900" with "1500"

FOR WINDOWS XP USERS; Download TCP optimiser. I've seen this recommended in the thread, although I'm unsure if it actually works as I'm not having this problem.
(thanks to Torchwood for that)

To do this on a Mac:
Apply icon > System Preferences > Network > Ethernet / Airport
> Advanced > Ethernet tab > Select "Configure: Manually" (from Automatic) >
Change MTU from "Standard (1500)" to "Custom" and enter 900




Use this at your own risk!

In the meantime, if this doesn't work - drown your sorrows with some smooth Jazz.
It's never too early for Jazz.

Uuuuuuuuuuupdated. Contains a Windows XP fix, now!

This worked a treat for me. Went from over 3000ms down to 30ms :D

Glad to hear it.

no fix for windows 7.. ?

Worked like a treat!!!

I've never had the MS problem that others seem to have constantly unless there really was a server problem, or nothing a /reload or game restart resolved, until today...

Thanks :)

Just sayin'

Yeah I can't get this to work.

'The filename, directory name, or volume label syntax is incorrect'

Yeah I can't get this to work.

'The filename, directory name, or volume label syntax is incorrect'

Dont type the initial quotation marks. Just type:

netsh interface ipv4 set subinterface "Local Area Connection" mtu=900 store=persistent

I didn't :/ I've tried it 3 times how it's written, doesn't work O.o

Now 6 times in slightly different ways. Still same thing.

What you should be typing is either...

netsh interface ipv4 set subinterface "Local Area Connection" mtu=900 store=persistent

or


netsh interface ipv4 set subinterface "Wireless Area Connection" mtu=900 store=persistent

Unless you're using WinXP. There's a seperate guide for that.

I've got the xp fix in place

I previously had home 33-46 ms World 2000-3000 ms

Now I have

Home 34-130 ms
World 600-900 ms

EDIT: Haven't moved & lag climbing up n up.
with fix in place

Home 33ms
World 1300-1500

This problem appears to be worsening even with the fix:

Now I'm at

50ms home
2934ms world

worked for me m8 ty ming if you go to the micrsoft page says dont set bellow 1400 o.O but it works so what the heck:) ty

Touché. Thanks. 33ms.

Worked, thanks a lot, if people are looking for their connection name, go to ur network and home centre, and check your connection. Mine was "Wireless Network Connection 3" so check ur connection name!

Glad these are helping. I bet you were all like "Oh, another bizarre fix that does nothing..."
Then it worked and you were like "lolwut?"

I'm used to nothing ever working. Last time I had a connection problem Virgin came and fixed it. Twice. Because they didn't f'ing fix it the first time >:( And my pc always breaks, and my phone always breaks... Yeah you get the idea. Nothing works. So I didn't expect this to.

Hm. Yes. Studying tech support. Good idea. Wutwut.
