No. I was rung one day by a lady at my ISP (Eircom), who told me I had been chosen as a recipient of their new "Ultimate" system, which would increase my speed from 5Mb/s to 14Mb/s, at no extra cost! Apparently this was not available to any old customer; I had been specially picked out for the privilege. I can't think of any reason why I should be picked out, except that I always pay my bills. (I have been with them for ever, and remember being told by them long ago that scientists had proved it was physically impossible for traffic down a telephone line to exceed 300b/s .) > If you are > running DSL with PPOE it might have been a registry tweak for windows to > reduce the MTU.

I'll try changing the MTU sometime, and see if it has any effect.
