EDIT: an AP is your access point for WiFi connectivity
Okay here is some more info, while browsing the Belkin website I discovered that they have completely new WiFi access points, unfortunately the Belkin WiFi APs will max out at 16 connections Belkin wireless networking, wireless N routers, and wireless apps
.So now lets take a look at Netgear. The PROSAFE WIRELESS-N ACCESS POINT WNAP210 only supports up to 30 connections, but you could buy two and pair them.
so with that you might want one AP so then PROSAFE® 802.11N‡ DUAL BAND WIRELESS ACCESS POINT WNDAP330
will get you were your going, but will set you back ~$330.
but that might not be the best solution, the PROSAFE® WIRELESS ACCESS POINT 802.11G WG302
is about $180 and supports up to 50 connections. and is cheaper, but you will loose some bandwidth/future upgrade-ability by going with G.
Then there is Linksys/Cisco. At our workplace we have this router: Cisco Small Business Pro AP 500 Series Wireless Access Points - Products & Services - Cisco Systems
, but will set you back about $350, unless you find it cheaper on the internet, this page might also be useful: Wireless - Main Page - Cisco Systems
