DSL Setting Deutches Telkom DD-WRT Router

Hi;

A bit of an odd problem.

Can anyone help me setup a Linksys WRT54GS-UK Router Flashed with DD-WRT to work as a a DSL Modem / Router on a Deutches Telkom Line for DSL.

I currently have a Speedport W 723V Type B which has to be sent back to D Telkom or I face a Euro 200 bill.

I live in Germany (for the next 2 weeks) and my Deutches Telkom Account was supposed to be terminated yesterday. Like all things D Telkom it has been delayed, despite having received a letter stating that it would be cut off 11 Nov 13. After a couple of phone calls it looks like it may not get disconnected until 31 Dec 13 by which time I would have left however they have stated that they want the Speedport Modem / Router back now????

To take advantage of the delay and avoid a bill for the router I want to use an old Lynksys 54GS the problem is I have not got a clue what settings I need to input??

Any help would be great.

Many thanks

 

No "pretty sure" about it. A modem is by definition is a "MOulator DEModulator" and is a separate network device. No amount of flashing can reprogram a router to perform as a modem.
