Pleas help. I have searched for days, through all documents I can get my hands on.
I am trying to configure my 1841 router to connect to my DSL over POTS from Centurylink. I have a static IP. I have contacted tech support with Centurylink and obtained all the info I could from them.
The following is from my show run:
!
interface ATM0/0/0
no ip address
no ip mroute-cache
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0/0/0.1 point-to-point
no snmp trap link-status
pvc 8/35
pppoe-client dial-pool-number 1
!
!
interface Dialer0
ip address 69.68.120.6 255.255.255.128
no ip redirects
no ip unreachables
ip mtu 1492
ip nat outside
ip virtual-reassembly
encapsulation ppp
ip tcp adjust-mss 1440
dialer pool 1
no cdp enable
!
ip route 0.0.0.0 0.0.0.0 Dialer0
!
When I show the interfaces, they all show up and a reliability of 255/255 yet I cannot ping my ISP gateway. When I show route, it shows that the 69.0.0.0 network is directly connected.
I know the connection is good. When I plug the POTS line into the old modem provided by Centurylink, I get connectivity. I am trying to get rid of the ISP provided modem and just go through my own router into the rest of my network
I am just lost. Everything I check says it should be connected, yet, I have no connectivity. I am aware that the wic is not capable of higher speed dsl connections, but, that should just limit my speed, correct? I have a HWIC on the way.

Hi Kevin,
Not sure if you completed this battle.
I had to order a DSL modem from CenturyLink (at $6.99/mo) to get the service up and running.
Tech support was about as handy as 2 dead flies.
Once i used their "approved" modem LCP came up and PPP negotiation completed.
I believe it is their pvc they used that got it running. Tech support could not tell me that.
I was them able to take some of the info from their modem and finalize my config and get my 1760 online with the new service. I will now work on returning the leased modem.
Below is my final configuration;
