% Password expiration warning.

Cisco Router and Security Device Manager (SDM) is installed on this device and
it provides the default username "cisco" for one-time use. If you have already
used the username "cisco" to login to the router and your IOS image supports the
"one-time" user option, then this username has already expired. You will not be
able to login to the router with this username after you exit this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to

This tells little of the internet connection

by seanferd In reply to cisco 851 no internet

except I can tell you use Charter from the DNS server address.

How is this networked? Router behind a cable modem? You are getting internet directly, just not through the router?

I don't see anything which indicates the modem the router is connected to, or anything behind the router for that matter.

(Note- you may want to change your security information since you just posted all of it.)

no internet

It is charter internet. I get internet when connected directly to the modem. Just no internet through the router.

It is a router behind the cable modem. Modem is connect FE4.
