Has anyone managed to get an 1841 with the ADSL port to get on the Internet? I have connected but get no web pages.
Here are parts of the config I use:

Hi,
Try this link http://www.cisco.com/en/US/tech/tk175/tk15/tech_configuration_examples_list.html it has everything about ADSL whatever the router model you have.

Thanks!
What I did notice was though if I ping from the routers console say www.google.com it would resolve successfully. From a laptop it won't but will if I put the IP of google's website in. I thought the import all option in DHCP would get the user to use the ISP's DNS servers?

Hi,
In your laptop MS-DOS CLI, execute "ipconfig /all" and check if you have a DNS. If none, follow the guide to include the DNS in the DHCP.
Can you check also the output of "show ip dhcp import" from the router if it returns with a DNS entry?

did you solve this issue I have the same problem

Hi, how far have you got, mines all working. All I had to do was add an Internet DNS server IP in the DHCP part.
Can you PC get onto Google by the IP, 72.14.207.99?
If so then its a simple DNS issue mentioned above.
Please rate this post

Man the issue looks very similar but instead a DNS ip address I just put this command on my internal interface ip tcp adjust-mss 1452 and this command on my dialer interface mtu 1492, then everything works!

Great, where did you get those settings from? It worries me that never set these mtu settings, everything works, but I wonder if things would be better if I did?

See link bellow! this issue is common when you have dls to internet and nat configured
