I have 2.2.7 with a Dec "tulip" ethernet card, and a Bay Networks
LANCity cable modem.  I installed 2.2.7 across the net using ftp option,
and it flew -- peak transfer rates of 120KB/s (KiloBytes!).  It
continues to perform well.

This doesnt really offer you much help, hearing about another success
story :)

Maybe barking up the wrong tree, but perhaps your problem is related to
an MTU size issue?  Although, with my configuration, it worked "out of
the box" with no tweaking of the ifconfig parameters...

Try a different brand/model of enet card if you can...big hammer
approach, but it quickly helps narrow the list of suspects...

What cable modem do you have?

I have a cable modem set up with a 2.2.7 box and have
been running fine for a long time now! In fact, I first
installed 2.2.5 on this box via ftp from ftp.freebsd.org
over the cable connection.

I routinely get transfer rates (ftp from well connected
sites) of 300-600 kbps.

Until recently I'd been running on a 3C509 card; I have
a Bay Networks LANCity modem.

Please email me if you have any questions.

Sanjay
