I'm choosing an APs to deliver Wi-Fi network in area with high clients concentration: 30+ clients in 100sq meters. I was thinking about creating a WDS to balance the load. I've done it last year, using 3 D-Link AP's in WDS, but after certain number on connections, the APs have stoped responding.
I need an advice. Which AP is preferable in this case(model), and how many I need? OpenWRT & large covering area are also appreciated.
