Please do not post in html on this list, plain text is preferred :-)

Is there any particular reason you are using the 2.6.30 kernel? When you
said that you 'compiled' the 2.6.30 kernel, I'm guessing that you did
this with a standard Jaunty install. Do you get the same when you use
the standard Jaunty kernel?

Can you please post the output of:

$ ifconfig

The first 3 lines of:

$ cat /etc/hosts

All of:

$ cat /etc/network/interfaces

Also please advise what the mtu settings are on the router/modem, and
what the recommended mtu settings are from your ISP. It is possible that
the default mtu setting of 1500 on Ubuntu is causing fragmentation. See:
http://permalink.gmane.org/gmane.linux.ubuntu.user/188941
for how you can test to see if the mtu setting is the problem.
