That depends where you use it. If you use it at university's library with smart networking design, even if many people connect it won't suffer congestion. Worse it comes to stores or coffee shops and especially public libraries which have poorly designed wi-fi networks. Some of them even use only linksys consumer grade crap and for backhaul use minimal adsl tier available!!!
