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 .)

It is PPPoE, I think.
I'll try changing the MTU sometime, and see if it has any effect.
Thanks for the suggestion.
