in general MTU should be 1500 I think (AOL seems to like 1400)

download SG TCP Optimizer

post your results.

Download Dr Tcp and set your MTU to

1458 BT original suggested setting.

Link with more MTU settings on http://www.kitz.co.uk/adsl/tweak2.htm

There isn't a defined optimum MTU value for ADSL (AOL being the exception where anything other than 1400 will give problems with https amongst other things). I found that 1452 worked best for me, at my parents place 1458 worked best but on spare ADSL line in the office be get better results with 1500.
