Think I've done that before but here it is again.
But you may have to interpret it as it looks like
it says 192.168.1.254 that it always has been.
lchata at ubuntu:~$ netstat -Frn

The router was unplugged yesterday while talking to ATT but the
problem existed well before I unplugged it.  I'm going to do a manual
reset of the router using the button on the back side but not before I
hear from NoOp and Nils who first responded to this thread.  Don't want
to do something to break the chain until I hear from them.  Thanks for 
your input and please tell me your thoughts on the output of netstat -Frn.
Does it not verify that my gateway/router IP is 192.168.1.254? I ask because
I'm not very network literate.
