I've got one of those dlink access points and it certainly is able to do what you are looking for. Have to say that it's one of the best bits of kit I've bought as it's got great range, reliable service and the build quality is superb. Setup via the web interface is relatively easy, using the console cable and cli requires more thought but isn't impossible. It's overkill for my uses as is the cisco 1921 router I use with it, but I was sick of having to reboot, dropped connections and poor wifi signal. Not had a hitch in nearly a year since getting it.
