See if you can ping your own interface. You should be able to ping it on=20
both the loop back 127.0.0.1 and the 192.168.1.128 address.
If you can ping those and still not the router at 192.168.1.1 check for=20
other defaultrouter statements. If you have only one of these statements,=
=20
I would bring down the interface and bring it up manually until you find=20
the correct settings. For instance you may need to set the line speed 1t=20
10 MBs, or 100 MBs or 1000 Mbs, or set the duplex setting. Oh and check=20
the LED's on your ethernet interface and router and hub/switches to be sure=
=20
you didn't knock a cable loose.
