glen2409: Tried but perhaps missed something and Everest still said MTU 1500
Stuartli: TCPOtimiser seemed to work and Download speed has improved.
There was a heart stopping moment when no Aol page would develop. Panic.... but Firefox worked properly straight away. So did Aol when I tried a second time! and my favourite speed test showed an improvement from about 1530 to about 1720 (max 2000).
Assume I should treat the Laptop similarly while the router just does what it does?
Everest still insists I have MTU=1500, and Yes - I did reboot each time I fiddled.
Perhaps I should just get out more, but its a murky miserable day out there.
I think you will find that TCPOptimiser states 1400 is the "correct" setting, but to use 1432.
Anyone who uses the TalkTalk (which also owns AOL) Connect 'n Go installation disk has the MTU set automatically at 1432; this is a lower figure than used by many ISPs, whilst the Windows default figure is 1500.
