Hi everybody,
we bought a used Cisco 1841 router with a WIC 1ADSL module and I am asked to configure it so that we can connect to Internet using our ADSL phone line.
Actually, I started via commands with some configurations found on the internet but it is not working.
I wanted to try via SDM interface, but could not launch and I don't know why.
Please anyone who deals with such a configuration or anybody who well knows about that kind of configuration will be very welcome.
Thank you a lot
NB: Informations got from my Broadband operator are:
login: MY_LOGIN
password: MY_PASSWORD
We got our LAN's individual IP address dynamically from our operator using its given setup box.
and the ranges are:
reserved: 192.168.1.1 to 192.168.1.9
usable: 192.168.1.10 to 192.168.1.100
I hope the above informations will help.
Thank you again.
Solved! Go to Solution.

Hi Landrybrou,
Please get the below details from your provider.
PVC details (VPI and VCI values)
Is this connection PPPOA or PPPOEOA?
Use below link to configure further.
for PPPOA

Hi,
Also please elaborate when you say "it doesn't work".
>Are you not able to get ip address from ISP?
>Internet is not reachable from LAN?
I will wait for the PVC details.

Hi,
I don't really know if it is PPPoEoA but I have already tried PPPoA configuration link you provided.
And it doesn't work.
But my architecture is made of the followings:
- an ADSL line connected to our 1841 router on the WIC 1ADSL port using RJ11 connector
- a router 1841 with 1 ADSL card and with 2 Fast ethernet ports.
- a switch connected to the router trough Fa0/0 port. and LAN PCs are connected to each other and getting access to Internet.
Anyway I will try to get thoses PVC détails from my ISP and let you know then.
Thank you

Hope this could help.
Thank you

Hi,
So this is PPPOEOA. Please use below link to configure your DSL line.

If it doesn't work, capture below information.
ping atm interface atm0 8 35 end-loopback
ping atm interface atm0 8 35 seg
debug ppp negotiation
debug ppp authentication

Hi,
I used the configuration provided by the link but still doesn't work.
Also I can't run these two commands:
ping atm interface atm0 8 35 end-loopback
GT_Internet_Router#ping atm interface atm0/0/0 8 35 end-loopback
Translating "interface"
^
% Invalid input detected at '^' marker.
ping atm interface atm0 8 35 seg
GT_Internet_Router#ping atm interface atm0 8 35 seg
Translating "atm"
^
% Invalid input detected at '^' marker.
Below is the capture of "debug" commands
GT_Internet_Router#debug ppp negotiation
PPP protocol negotiation debugging is on
GT_Internet_Router#debug ppp authentication
PPP authentication debugging is on
Please find below the running configuration:

Note: I can't set "vlan interface" on my router
GT_Internet_Router(config)#interface vlan 1
^
% Invalid input detected at '^' marker.
so I configured Fa0/1 instead of Vlan 1 for Telnet purpose.
Is there any problem ??
Also I want you to check the atm interface
GT_Internet_Router#sh interface atm0/0/0
ATM0/0/0 is administratively down, line protocol is down
Hardware is DSLSAR (with Alcatel ADSL Module)
MTU 4470 bytes, sub MTU 4470, BW 800 Kbit, DLY 640 usec,

VC Auto Creation Disabled.
VC idle disconnect time: 300 seconds
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Hi,
First you bring the ATM interface up.
GT_Internet_Router#sh interface atm0/0/0
ATM0/0/0 is administratively down, line protocol is down<<<<<
Hardware is DSLSAR (with Alcatel ADSL Module)
MTU 4470 bytes, sub MTU 4470, BW 800 Kbit, DLY 640 usec,
reliability 0/255, txload 1/255, rxload 1/255
Go to interface ATM0/0/0 and apply "no shut"
Status should be as per below then only you can move further
GT_Internet_Router#sh interface atm0/0/0
ATM0/0/0 is up, line protocol is up
use below commands to ping via PVC
ping atm interface atm0/0/0 8 35 end-loopback
ping atm interface atm0/0/0 8 35 seg
