Try removing the splitter, if it works then you might have a faulty splitter and you need to get it replaced. You might check if you are using the first phone jack in your house / apartment. I remember that was key when i was on DSL. Hope you get it sorted out, not having a working connection is very annoying.

You need to connect the phone line to the DSL splitter... From the DSL splitter you will have 2 RJ11ports. one should be connected to the telephone and another should be connected to the modem....

Networking Configuration A network architecture is a set of standards for how computers are physically connected and how signals are passed between hosts. Some typical network architectures are described in the table below.
Network Architecture Description Ethernet Ethernet is a wired networking standard and is the most common networking architecture used in LANs (both in business and home networks). Dial-up Modem Dial-up networking is a common way to connect a computer (often your home computer) to a remote network, such as the Internet or a business network. A modem on each computer uses the phone lines to send and receive data. DSL (Digital Subscriber Line) DSL is a fast-growing alternative to dial-up networking to connect to the Internet. DSL uses regular phone lines to send digital broadband signals. ISDN (Integrated Services Digital Network) ISDN is another alternative to traditional dial-up that can be used to connect to the Internet or to directly communicate with another computer connected to the ISDN network. ISDN is more common in Europe than in the U.S. ISDN can use regular telephone wiring, but must be connected to a special ISDN network. Wireless Wireless networking uses radio waves or infrared light (with the air as the transmission medium) to send data between hosts. Wireless networks are common in homes, businesses, airports, and hotels. Most wireless networks connect into larger wired networks (such as LANs) which are in turn connected to the Internet. Communication between hosts on a network generally takes one of three forms:

• Simplex--one-way communication from a sender to a receiver.
• Half-duplex--two-way communication between two hosts. Communication only travels in one direction at a time.
• Duplex--two-way communication between hosts. Communication can travel in both directions simultaneously.

Sounds like you are missing AAA author for your PPP sessions. Without seeing your config, it is a bit hard to give you more help.

If you want to receive "incoming" telephone-calls:

ADSL modem <---> Linksys SPA <---> wrtu54g <---> wired computer

and Linksys SPA <--- telephone-line-1 --> telephone hand-set
and Linksys SPA <--- telephone-line-2 --> FAX machine

or Linksys SPA <-- telephone-line-1 --> mechanical telephone-splitter
with telephone-splitter --> hand-set
with telephone-splitter --> FAX

Please let the fax line be connected to computer itself do not remove , In the DSL line you get a splitter which the lines for phone and ADSL modem connect the splitter to DSL Line and from the Splitter you 2 o/p ports with phone marking or symbol connect the phone line to it and to line port connect the main 8957and then to ADSL line to ADSL modem from the ADSL modem connect to lan port which is behind the computer (not to dial up modem
i.e is fax line ) or the usb port in the computer ...

Good luck...

First of all what type of phone line r u using ....is it a normal phone leine or DSL....

IF u have a DSL...u need to have a splitter...
If u have normal phone line then connect it directly to printer in the line jack...and from Ext jack to phone...

Check if get on hook dail...ie..see if u can hear the dial tone...

Try sending a fax and if u get a msg "fax Complete " then its working

Hey Tony - Did you recently hook this up to the DSL for the first time? This unit is supposedly not able to work with a DSL line.

The fax modem in your AIO is an analog device and cannot be used on an ISDN, DSL, or PBX digital phone service. However, you can connect certain devices to your AIO that let you use the fax function in addition to these digital phone services.

To connect without an unsupported line:
Connect an active telephone cable from the AIO to the telephone wall jack.

To connect with an unsupported line:
• If you use an ISDN phone service, you can connect to an analog telephone port (an R-interface port) on an ISDN terminal adapter.
For more help and to request an R-interface port, contact the ISDN provider.
• If you use a DSL (Digital Subscriber Line) phone service, you can connect to a DSL filter or router that will allow for some analog (rather than digital) use.
• If you use a PBX phone service, you can install an analog phone line for a fax machine.

If this was working on the DSL let me know. I don't know the location but obviously a separate phone jack is the easiest. Let me know. If this helps you fix it you can rate this as fixed. If you are just going to rate this as helpful I'd rather you please not rate it and just add a comment and say thanks for the info.
If you need more help just add a comment and I'll be glad to assist you further. Thanks.

just a suggestion, there are free modem firmware updates from cisco's FTP site to most 800 series routers. The firmware also get updated with a major IOS release, have you tried?
just download the correct one, instructions are on the site to download. Basicaly you rename the file and save it onto your flash. the check with "sh dsl int" in enable mode, it will list the FW as "external" source. When renamed or deleted, you are back to the original.

hope that will help.
