Bug#390752: navigation slowdown connected to terminal Ericsson F251m

["rodrigo valiña gutiérrez" <rodrivg@gmail.com>]

Package: kernel-image-2.6.8-2-686
Version: 2.6.8-16

I am using Debian 3.1r0a Sarge and I connect to Internet with a serial
modem plugged to the phone line which ends into terminal "Ericsson
F251m".

When i connect the Linux box to the modem:

1) navigation is much slower than from the Windows box with same
hardware and configuration. but downloading with wget or similar ir
equally fast.

2) I can not connect to my msn account not with Gaim not with aMSN

the avobe problems dissapear if I connect the Linux box to a Windows
box with DHCP.

so it is strange.
maybe a bug in PPP?
