> What is TDS?
Many people would find a quick Web search for, say:
TDS DSL
to be easier, faster, and more reliable than a question like that here.

TDS offers different DSL speeds in different markets.
So (even if you're not among the helpless), by itself, "TDS DSL" is
not enough information from which to conclude much of anything.
> They won't provide that info as they want you to rent from them.
What, exactly, do "they want you to rent from them"? Can you rent it
for a month, for educational purposes, whatever it is?
If you don't get many responses from TDS customers in a Netgear DSL
forum, then you might interpret that as a clue. Netgear seems to have
lost interest in DSL. I'd look elsewhere. A Web search for, say:
TDS DSL modem
might uncover more useful information more quickly. If you can
determine what's supported or what works, then a little Ebay exploration
might find something with a suitable modem at a reasonable cost. If
that device turns out to have a lame router, then it'd probably be
possible to retain its modem, and add on a more capable router.
