Hi, I'm Magic, and thanks for asking your question on JustAnswer. I will be glad to help you.
Is your Cisco router setup to receive a DHCP address on Fa0/0?
What you will need to do is use a configuration similar to this:
interface fa0/0 ip address dhcp no ip unreachables no ip proxy-arp no cdp enable
This will allow fa0/0 to receive a DHCP address.
on the inside interface, more than likely, it should be fa0/1. That would be configured for any internal NATing that you want to do
most cable ISPs use the 10.x.x.x range for their management IPs, so I would use the 172.x.x.x or 192.x.x.x range for your internal NATing.
you will need to setup the DNS servers directly as well.
just ask TWC customer service what the DNS servers are.
make sure that after you disconnect your computer from the cable modem that you powercycle the cable modem for at least 30 seconds and remove the coaxial cable from the modem. This will clear out all provisioning statements that your modem may have.
afterwards, reconnect all power and coax, allow your modem to sync up, then plug in your router.
interface fa0/1 ip address 192.168.1.1 255.255.255.0 no ip proxy-arp ip nat inside no ip route-cache no cdp enable
ip dhcp pool internal network 192.168.1.1 255.255.255.0 default-router 192.168.1.1 dns-server 220.127.116.11 18.104.22.168 <-------put RR Turbo DNS servers here
access-list 1 permit 192.168.1.1 0.0.0.255
Let me know if this helps
The configurations you provided are very similar to what I have. Yes, Fa 0/0 is set to DHCP as my outside interface, and Fa 0/1 is set statically for my inside interface. I was able to get my internet working by changing how my router sends traffic out.
I have some questions about statements in your configuration though. What is the purpose of the "no ip proxy-arp", "no ip route-cache", and "no ip unreachables" statements?
What got my internet to work was removing the line "ip route 0.0.0.0 0.0.0.0 fa 0/0", then adding the line "ip dhcp-client default-router distance 1"
the purpose of no ip unreachables is to disable ICMP unreachable messages.
the purpose of no ip proxy-arp is to disable proxy ARP on the interface.
no ip route-cache disables switching methods for forwarding IP packets
that sounds right removing the IP route statement since you don't have a static IP address.
I'm assuming that the ip route statement was from the default configuration?
I had the ip route in my configuration so that any other traffic would be sent out Fa 0/0. My configuration had been working fine before I moved with that line in the configuration.
Ah, ok, that makes sense. Has the TWC area you moved to been upgraded to DOCSIS 3.0 yet? Most of the TWC areas are being upgraded to the new standard, which enables speeds up to 50M x 5M.
I believe they have. They are calling it "wideband" internet, but I can't justify paying what they want for it.
It all depends on what is needed.
with the new higher speeds comes a higher "standard" RR Turbo speed as well
now standard RR has gone from 7M x 384k to 10M x 1M, if I'm not mistaken
I think RR Turbo is 15M x 1.5M, or something like that
RR standard is supposedly 10x1 and RR Turbo is supposedly 15x2
I went with the Turbo since I support my parents computers so I am grabbing files from my home servers at times.
Very nice upgrade to speeds!!
