what kind of router needed for dorm
802.11ac routers tend to be more expensive. As for routers, it doesn't really matter what kind you get, just look to make sure it uses the 802.11n frequency. As for speed, the dorm's internet speed I guarantee is slower than the router's max speed so that shouldn't be a problem. Also know that if your internet is slow, it's not because of the router, it's the dorm's internet speed. Plenty of options at your budget.
