Hello Pete, Hmmm, this looks like the mru may be off .
do you know what mtu/mru values are being used by your
provider ? I draw this from the output you included
there aren't any 'begin ppp packet' ie:'~' chars at the
beginning of each frame . they all seem to a bit skewed
with a '~' at the end of most . Their end -may- be chopping
them up based on their local mtu/mru & your end isn't
reassembling the packets correctly on receipt due to the
mru/mtu differance .
