Im on talktalk broadband but wish to use 1 of 2 wireless routers i own to install the talktalk settings into?

To use my laptop wirelessly. i have an orange wireless livebox and a buffalo g54 airstation but as of yet have been unable to install the talktalk settings. i am not prepared to pay talktalk another 50 pounds for their wireless router when i have 2 already. can somebody give some instructions on how to get either of my routers to work with talktalk?
Answer
Not sure but it may only work correctly with the makers own router at one time you could only connect if you were on bt broadband with the supplied modem
