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... --Lee McKenna lee.mckenna@lodgenet.com -----Original Message----- From: Sanjay Waghray [mailto:sw@home.com] Sent: Thursday, October 01, 1998 11:24 PM To: LITE solutions Cc: freebsd-net@FreeBSD.ORG Subject: Re: extremely slow and strange connection with cable modem and 3c509 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.
