Dr TCP MTU query

[CurlyWhirly]

I have seen references to Dr TCP http://www.aopr43.dsl.pipex.com/ppages/tweaks.shtml

In the above article it is mentioned that BT themselves recommend an MTU of 1458.

Firstly is there any way that I know what my MTU is set to as I can see no mention of it in my routers stats
If so is there a way to alter the router setting I wonder?

Also I have run Dr TCP and changed the MTU to 1458 but I assume this only changes the XP setting and not the routers setting

Should I have left the MTU where it was before (whatever that was) and if so I can get my original back by simply deleting the existing MTU value and selecting 'save' and it then goes back to default settings.

Does altering the MTU make any difference or is it a waste of time

Yep, playing with Dr TCP will only change the MTU on the PC, you'll need to do the router manually.

Mmm. I would like to have a go and change it but I don't think my router supports it

It is a Thomson SpeedTouch 546 Ethernet ADSL Router.
This is why I wondered about a firmware upgrade in another thread but I already have the latest version.

I don't expect there's a way around this problem so I will just have to live with it
