Hello everybody.

I have a cisco router 1721 and I am trying to set it up on the internet with bt broadband but it seems a never endding problem.
I have no problem in configuring the network locally.
I have a wic adsl card (ATM0 interface).

How can I get this done, what's the configuration?

Any help really appreciated.

cheers
Arruda

That's the thing guys, I don't even know where to start.

I have got an ideia of ATM0, as in router>enable, conf t, int atm0 and then work my way in there but I would be lying if I'd say I know what I am doing. I even tryid smd software and can't get it to work.

In my CCNA study so far I haven't yet been through this, just wan connections using serial links with PPP encap, RIP and EIGRP or IGRP, etc...

Here it is my start conf...

Any help well appreciated...

Cheers
Albert, C

 

you have typed in your username and password correct haven't you? or is it set as whats listed above?

 

well in the BT home hub there is no user password never ever has been one but the sdm wasn't allowing me to go without one so I just typed home which apparently can be anything if required by the devices software so I was told along time ago by BT....


help please

Just want to see this great piece of kit working...

thanks for everybodys help

cheers
Albert, C

 

that username only works with homehubs, I'm pritty certain you should be using the primary account([email protected]) details on other modem/routers. Also look at your nat.

 

So with BT on an ADSL line, were you given a username / password at any point, as far as my understanding with ADSL, all ISP provide their user with some sort of credentials, username/password, so they "dial in", especially with those shi77y usb modems that were shipped out FOC.

Now-a-days, people buy decent ADSL modem/routers and enter their credentials one-off on their setup page when they configure their device for the first time.

I am thinking along the same way here, unless your device does not support ADSL connections

 

When I changed to a non-BT router (around 6 months ago), you simply needed to enter your BT email address which you should have set up when you first signed up with BT, and no password required.
Pretty sure the bthomehub one won't work when not using a home hub though

Are there any entries on the original router you can copy/check with?
Cheers

 

Done some changes guys but to no luck.

I have changed username and password to bt username <username>@btinternet.com and the password they provided but no luck.

I am totally lost as I have never tryid before to setup an adsl wic card so I am lost.

Any help welcome,

Cheers
Albert, C

Any ideias please?

Maybe clear the start up file and start a clean one step by step?

Cheers

 

Can't help on the cisco config side I'm afraid - but with regards to the username/password when I used BT Broadband they mentioned that from their end only the username was required but some routers would require a password to be entered, if this is the case they said to use "bt" (minus quotations)

 

albertc30,

Does BT provide you with a pre-configured networking device such as a modem or router?

This is from an 877Sec+ so just takeaway the bits you don't need and you should be cooking with gas

 

at what level is it failing ? your going to have to run some debugs
i.e. is the ADSL synching ok ? then it sounds like a PPP problem

 

Well, I don't quite know yet. What I do know is that I have bt broadband and it works fine in my bt home hub.
I have setup hundreds of adsl internet connections in the past using the GUI and always have been successful but never did I setup an adsl internet connection on a Cisco router.

What I will do is I will erase the start up file and have it done from scratch. I'll use the information that you guys already provided me with and we'll see how it goes.
I am just getting prepaired to take my final exam module 2 on CCNA. Haven't yet talked about how to setup adsl lines or internet connections and we just have mentioned once about the debug mode.

I'll keep you guys posted.

Fingers crossed.

Thanks to you all.

Albert, C

 

Good luck bud, nothing worthwhile is ever easy

you could try debug ppp (i think that correct) if your interface is up.

At the back of the router in the adsl card there is three lights the ones on are CD and OK the LP is off, hope this helps.

Anybody please help...
Cheers

 

Your going to have to get your hands dirty and work it out
as usual Google is your best mate etc...do a search on debug cisco adsl connections
1st debug the ATM0 connection to prove layer 1 , then if thats successfull go on to layer 2 - PPP
I had to upgrade my adsl firmware on a 851 adsl router to get the ATM0 to come up, but you have a WIC
card in there.... this is where your troubleshooting skills get developed

 

albertc30,

FOR THE SECURITY OF YOUR FRIEND/CLIENT, YOU MIGHT WANT TO EDIT THE EMAIL ADDRESS @BTINTERNET.COM IN THE ABOVE CONFIG.

 

Hello everybody.

Hello Negseven, I can see you are a new member so welcome to certforums.
I appreciate what you have said and I must agree with you but you see, it's just that I don't even know if the setup is correct. I can do the first one, debug the ATM0 to check layer 1 which I am pretty sure I don't have any problems here as I do have internet through a BT Home Hub.
Now as for the layer two PPP, shouldn't the connection be done properly first? I do not know it and to be totally honest like I have, I have got no idea of what I am doing here. I have never ever done it. I am confused with all the ATM0.1 and dialer0 and dialer1, where did these all come from??? I am definitely at an obstacle and I need to overcome it and most of all, learn from it. But still, you are right negseven. Once again welcome to certforums.


Hello R.H.Lee,
About your comment not to worry as the username in the post is not our real e-mail address. Thanks for the concern.

To everybody,
I would like to do here is to learn on how to setup the ATM0 interface for my ADSL connection steep by steep as I have mentioned above, I am totally and utterly lost with ATM0.1 and Dialer0 and Dialer1 and what I don't really want is to be copying lines here and there and just pasting it into my routers configuration without having a clue of what they do or what do they mean.
I am happy to have found this website as it is of the utmost importance to allot people as it sure is a great help to all of us. To all of you that have shed some light into to this my much appreciated thank you.
Hope to learn allot more with you all and hope to be able to help as well.

Cheers,
Albert, C
