Any router will work.  Don't fall for the high speed hype, just get a standard 802.11g router.  A dsl connection will run no faster than what your ISP provides, usually less than 5 Mbps.   The standard 802.11g routers run at 54 Mbps, which is way faster than the internet connection, so any router that advertises speeds higher than this will do you absolutley no good in terms of internet connection speed.
