Using Cisco 881w as primary router for internet & Wireless

[eddie.sardinha]

Hello All!

I am hoping you can assist me in the configuration for replacing my Verizon Fios router with a cisco 881w.  I am studying for my CCNA and thought I could use this as my primary router so I'm forced to troubleshoot/test it.  I have one internet connection from Verizon and it handing out an IP via DHCP (not static).  I tried setting the interface of the 881w to dhcp but I never picked up an IP.  Does Verizon need to change a setting?

Any thoughts or ideas would be appreciated.

Thanks!

can you share the configuration of the internet interface of the 881W

[eddie.sardinha]

Sure, this is the running config below.  FastEthernet4 is the wan interface.

I take it the fast Ethernet 4 interface is up and up. if you connect a PC/laptop instead does that pick up an IP address? Are you sure of the setup from Verizon it is a straight Ethernet connection and not PPPoE?

[eddie.sardinha]

yes the interface is up and up.  I'm not sure about the Verizon connection but I know that the router/modem is connected via Ethernet.

[eddie.sardinha]

see interface status of fa4

Eddie,

If you connect a PC/Laptop instead of the router does that get an IP address?

[eddie.sardinha]

Richard, thanks for your help.  I gave up and called Verizon, they had to release my IP address or I had to reset the router as they said.  For some reason it wouldn't release/renew the IP and the only way to do so was either reset the router (erase all config) or to call Verizon and have them do it.

I think I can take it from here, at lease now I can focus on getting it to be my primary router.

Thanks!
