Hi all. I've followed the instructions on how to amend the MTU size, but I get an error which read "Element not found". It's not referring to the name of the connection because that brings up a different error message. Any advice please? Thanks.

Are you using XP or Vista?

Whoops stupid question - just realised this is in the Vista section :doh:
Are you following the instructions on this page?

Yes, those are the exact instructions I am following.

>> "Element not found".
I'm not sure at which stage its giving you that error, but at a guess at step 3? - Setting the MTU value
>> It's not referring to the name of the connection because that brings up a different error message.
By that I'm assuming that youve made sure the network connection name is correct - and youve checked by putting in a 'wrong name' which is when it gives you the different error message.
Have you made sure that you are running cmd as Administrator (step 2).
How are you connecting to the internet by wireless or Ethernet to your router?
The error message seems a bit vague - almost as if it cant find the correct adapter to change.

Correct, I get this message when hitting return after typing in the command to set the MTU value

Correct again, I've tried typing in the incorrect connection name and I get a different error message
Have you made sure that you are running cmd as Administrator (step 2).
Yes, I am running cmd as Administrator
How are you connecting to the internet by wireless or Ethernet to your router?
I am connected wirelessly

Your guess is as good as mine ;D

If you want you can paste the results of
netsh interface ipv4 show subinterfaces and
ipconfig /all
so I can have a look and see if theres anything glaringly obvious..
>> Yes, I am running cmd as Administrator
but I will be honest and say it should work then and I cant think of any reason why its throwing up that particular error
Ive tried googling it, but its so vague that it can apply to lots of things - but normally if it cant find the device you are trying to amend. :/

I had this problem and here's how i solved it (for anyone else who's spending hours searching the net for a resolution!):
Rather than use the name of the interface, i used its numerical ID. To get that ID, enter the following at a command prompt:
netsh interface ipv4 show interfaces
Once you know the ID for the interface you want to tweak the MTU on, use that rather than the description:
netsh interface ipv4 set subinterface “X″ mtu=1384 store=persistent (where 'x' is the ID of the interface)
