Router / ISP / ADSL Advice

[Bibio]

are yo running zonealarm ... if so it might have updated/defaulted to a loopback address...

the other thing that can happen is that the remote access has been left on in your router and the u/p has been left to default .. this would let people in to mess with the router settings...

other than that if you have updated the firmware in your router then the wireless authentication has gone to pot. and you need to set up your wireless card/router in the laptop to talk to each other again.

I can ping the routers LAN IP via the wireless connectino from my laptop.

Wireless comms between the laptop and the router work fine. Its the router to the outside world that doesnt work.

You have eliminated the wireless connection on the route with physical cabled connection have you and tested again?

not trying to be cheeky ... but how are you able to post if your internet connection is down?

another thing to try is connecting the laptop with a cat5 cable and see if it works...

You don't appear to understand the problem. It's the PPP CHAP authentication on the ADSL line that's not working.

Nope you right... Sorry.

The Challenge Handshake Authentication Protocol (CHAP) verifies the identity of the peer by means of a three-way handshake. These are the general steps performed in CHAP:

1. After the LCP (Link Control Protocol) phase is complete, and CHAP is negotiated between both devices, the authenticator sends a challenge message to the peer.
2. The peer responds with a value calculated through a one-way hash function (Message Digest 5 (MD5)).
3. The authenticator checks the response against its own calculation of the expected hash value. If the values match, the authentication is successful. Otherwise, the connection is terminated.

This authentication method depends on a "secret" known only to the authenticator and the peer. The secret is not sent over the link. Although the authentication is only one-way, you can negotiate CHAP in both directions, with the help of the same secret set for mutual authentication.

This would explain why when you went to the loo it disconnected, as it continues to authenticate. So I would challenge your ISP as it looks like the password or ID has expired, or your ISP is not accepting you ID even if is it valid.

There is rather alot of nice information on the cisco site about it.

Thats what I told my ISP and they dont agree with me. They reckon its my router. I told them I believed the probem was with their end i.e. my account is the problem and they are now ignoring my emails. I escalated it to my account manger who told me the tech guys say theres nothing wrong and now I'm going round in circles.

only because you can ping the ip addy it does not mean that you have an out side world connection.

for the card to talk to the routers outside world it needs authentication... if the wireless router/card settings are not set up properly then it will not let you see the outside world.
