You can make the surrounding area wireless. If youre getting it for dirt cheap, id say get one, but wifi routers such as the belken pre n can get you much better coverage , functionality and options for not so much more if you look around.
I personally dont like D-link because everything ive bought broke , but im sure someone will tell you otherwise. I prefer linksys. Netgear is good, but ive had my problems with them too. I vote 1 for linksys for noob friendly setups.
