Ok, we need to get some info straight here.
We are talking about the box that connects to your phone jack in the wall right? This is the modem.
If you are looking for this, then somebody I know loves this brand :
Hawking Technologies That is a link to their ADSL Modem. It is only a modem and is meant for connecting 1 machine up to your ADSL. If you need to connect more than one machine to your ADSL, then
THIS is what you would look for. Which includes a 4-port switch. So you can setup up to 4 machines instantly with no other hardware.
If you ALREADY have an ADSL modem, and you are looking for a router, there are tons of routers out there, and just about any one that says Broadband DSL on it will suffice.
From what I've gathered you are looking for the former, the ADSL Modem itself. The Hawking's one will work well, because it is ethernet and NOT USB!. USB is a windows technology that MS has basically forced the world to adopt. Do not get fooled by its ease of use. For the most part, in my experience ( except with Apple ) USB is a headache, and it only works with the vendors that pay the most to have the support built into Windows. That is a whole other debate that is totally off topic.
I usually buy from CompUSA because I have a card
They don't carry the Hawking's stuff.
CDW does carry Hawking's stuff. I don't know why some places don't carry the Hawking's stuff, but this guy I work with swears by them, and sells nothing but them as often as he can. So go with CDW, and if you have a problem, they are really cool about returns, and helping you out.
Hope this helps. Let me know if you have any more questions.
That'll be $75 US please
