I agree that the modem and router should be separate. Make SURE to get a modem that is either a modem only, most today are not. Most have a built in mini routers that need to be turned off, this is called bridge mode. So make sure the modem you buy can be set to bridge mode. Otherwise you will get dual natting that can cause all kinds of problems. I switched my neighbor last month from a Linksys to an AirPort Extreme and the AE reported dual atting taking place, he never knew it was happening, I gave him an old DSL modem in bridge mode and the problem disappeared. I used 2 Westell DSL modems that were set to bridge mode for years, they gave the best speed and reliability. I still have one DSL line as a backup. BTW, I use a Zyxel USG 100 router since I have dual WAN, ATT DSL and Comcast, and I use Apple Extremes as wifi bridges, they never have problems which is why I like them. The Zyxel is overkill for you, BTW Zyxel makes DSL modems too. You can find DSL modems on Craiglist.
