That is what seems to b happening.  Xchat works and Evo starts off-line,
but works when I put it back online it works fine.  My browsers don't
work at all.  I get warnings to try again; that they are offline but
won't go back online.

]$ service network status
Configured devices:
lo eth0
Currently active devices:
lo eth0
]$ service NetworkManager status
NetworkManager (pid 2442) is running...

]$ cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 192.168.1.1

Re-read man resolv.conf "
"  On a normally configured system this file should not be necessary.  The
       only name server to be queried will be on the local machine; the
domain name is determined from the host name and the  domain  search
path is constructed from the domain name."

So who or what is 192.168.1.1?  Can it be my cheapo router?  My
household network is simple. Cat5 lines leading from ever room in the
house (bought the house that way) to the router; three computers in
different rooms connected to the router; the router connected to the
cable modem; and, out.
