Trying to configure an 891-W on my home network.
Basic TW cable modem ---> 891-W with DHCP
I have done the following and are getting an IP address but no internet.
I have FE8 set as DHCP and VLAN1 as 192.168.1.1 255.255.255.0
I originally thought that "WAN GE 0" would be connected via my modem but I had no luck there either so I set FE8 as WAN?

Hi
it should be interface FastEthernet8 overload.
Thanks
02-01-2013 11:13 PM
Your config above has
no ip routing
First of all you'd better change this to
ip routing
02-02-2013 01:08 AM
Hi,
to add to the 2 previous replies, get rid of these 2 static routes as first they are pointing to a multipoint exit interface( which is highly discouraged for performance reasons and may not work if the next-hop is not implementing proxy-arp) and secondly because they are not needed as dhcp is advertising you the default route.
---->
no ip route 0.0.0.0 0.0.0.0 GigabitEthernet0
no ip route 0.0.0.0 0.0.0.0 FastEthernet8

Thanks for the responses, can I just delete the lines from my config and reload using TFTP or is there a command that will remove these using the CLI?
no ip route 0.0.0.0 0.0.0.0 GigabitEthernet0
no ip route 0.0.0.0 0.0.0.0 FastEthernet8
02-02-2013 06:19 AM
Those are the commands you enter via the CLI, the 'no' negating the previously entered commands. You need to enter global configuration mode, so it will look something like:
router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#ip routing
router(config)#no ip route 0.0.0.0 0.0.0.0 GigabitEthernet0
router(config)#no ip route 0.0.0.0 0.0.0.0 FastEthernet8
router(config)#exit
router#
You'll have to save the config before rebooting otherwise any changes will be lost.
02-02-2013 06:36 AM
OK done. What about this comment from above "it should be interface FastEthernet8 overload."?
I will connect the router to the modem via the FastEthernet8 port and try again I suppose.
02-02-2013 07:12 AM
Still no Internet, but router and laptop are getting IP address, if I do IPCONFIG /ALL everything looks good, DNS is 209.18.47.61 and 62 which I assume is Time Warner?

You should be trying to use the 'proper' WAN port (Gi0) rather than Fa8 as the latter is a switch port. Now that you've made the above changes, try using Gi0 again but first add:
ip nat inside source list 1 interface GigabitEthernet0 overload
access-list 1 permit 192.168.1.0 0.0.0.255
If that fails to work it might be worth reposting your latest config.
02-02-2013 08:37 AM
I made the change as you suggested but still nothing, perhaps my VLAN is off?

Still nothing, if I run the ever so helpful "network diagnostics" on my laptop it states "cannot communicate with DNS server". I'm running Windows 8 btw.

Hi,
save your config and reload the router.

Hi,
Can you post the output of ipconfig/all from the PC.
