I have a 2Wire wireless router that came with my ATT DSL connection. Now I am looking to buy a Dlink Wireless router. I noticed that DLink doesn't have the telephone cable input that the 2Wire router has. Dlink has the ethernet input. So how do I hook up Dlink?
Can I just put a ethernet cable from one of the 2Wire ports to Dlink? Will it work?
The reason I would like to do this is to use the faster wireless modem and access the security services Securespot 2.0 D-link provides.
Yes, you can probably run your D-Link router off one of the ethernet ports on your AT&T router. You will probably have to configure your D-Link as an "access point" first, otherwise, it may try to assign it's own IP addresses and will probably conflict with the AT&T.
I'm running a Belkin wifi router in another room as an access point off the ethernet of a D-Link wifi router by the modem. Not only do I have an access point on an alternate channel in the case of heavy interference, everything behind the second router is behind a second hardware firewall.
Keep in mind, not all routers may do this and your ethernet and wifi speeds will slow to however fast the slowest router is. Also, it might just be easier to take the D-Link back and get something with an input for your DSL modem.

First, the reason the 2Wire has a telephone cable and the D-link doesn't is that the 2wire is a wireless router and a DSL modem in one. The d-link is just a wireless router. You will need to use both together or buy a different dsl modem/router.
Second, there are two ways to handle this. The easiest is to do as wildwell suggests and plug the d-link into the 2wire leaving everything else as is. The d-link will connect itself automatically and anything you connect to it will probably work. There's a small chance that the D-Link and the 2Wire will use the same internal IP address space(the same subnet i.e. 192.168.X.X), which would cause problems, but you might get lucky.
But even if everything goes fine, you'll still have a situation which can lead to issues depending on what you're using your internet connection for. Having your computers behind 2 routers generally leads to problems in high badwidth applications like gaming and any port forwarding you might need to do. You'll also see some reduced speed and higher latency, since your traffic is being actively routed through two routers.
The cleanest solution requires a bit of work on the 2wire and d-link. Since you want to use all the features of the d-link, the best thing to do is to shutdown all of the router functions of the 2wire. Turn off the wireless and all of the router functions. You want to set the 2wire into a modem only mode. This casues it to act as a simple modem doing the initial translation on the DSL connection. The caviate is that you need to set up the d-link to login to the DSL network and get your IP address assignment. Most DSL providers use a protocol called PPPoe for this. You may be able to figure out your login by poking around in the 2wire's settings, but you pobably used it when you first set it up, unless you had it professionally installed. After the 2wire is in modem mode, you need to setup d-link to do all the work, which means poking around in the D-link prefrences.
This is how I've set up my home network, but if that's all too much heavy lifting , I suggest going with your first option and dealing with any problems as they come up. If you have a techie friend looking for a small challenge, set this one in fornt of them. Bribe them with food and drink. Always works for me.
