Thanks so much for your offer to help!

I haven't contacted tech support yet b/c I've been told if it's Linux
then they're pretty much useless.  This is a dual boot machine w/ WinXP
pro and I can't tell that anything is wrong in that (Win) so I don't know how
to frame my question to tech support to make them think it's a Win box.

Modem Hardware MAC from the back of the modem is
0020406FB53E

How should I have known that the problem was collisions?  ifconfig shows
errors on eth0 tx but reports them as carrier and not collisions


eth0      Link encap:Ethernet  HWaddr 00:04:5A:7F:D0:D0  
          inet addr:24.163.32.149  Bcast:255.255.255.255  Mask:255.255.255.0

          inet addr:127.0.0.1  Mask:255.0.0.0

          RX bytes:15220568 (14.5 Mb)  TX bytes:15220568 (14.5 Mb)

Also, why so much traffic on the loopback interface?

Again, everything "seems" to be working in that I can surf fine and
send/receive mail (now that I edited /var/spool/postfix/etc/resolv.conf)

The routing table looks OK to you?


Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

169.254.0.0     *               255.255.0.0     U         0 0          0 eth0
127.0.0.0       *               255.0.0.0       U         0 0          0 lo

Again, I really appreciate your help.
