Hi, I need recommendation for conference hall. I've recently had problems with the WiFi. I have WDR3600 with OpenWRT installed and replaced with WDR4300. I think I installed sysupgrade on OpenWRT, but he unfortunately failed when in the last conference we were trying to access with 40 laptops some database. They've downloaded 2-3GB and the router couldn't handle it. Now the router in the hall which is for 100 people max is Mikrotik RB951Ui 100Mbit version. I see also that I must implement QoS in the central router - Mikrotik and have it in separate VLAN.
