Hi experts, i have a question on network design. I will be setting up a wireless network for some 2000 possible 5ghz wireless clients. I will be bringing in a 100m pipe into the venue for the internet. This will only be for internet access, simple browsing. I have a FortiGate-100D router that i will use for the router and dhcp. I have some netgear GS7487 switches laying around, so i want to used those. I will be using Xirrus access points for the wireless. Here is my question: Would it be best that i create Vlans to break down the network? I can create vlans on the switches and the router supports creating multiple dhcp scopes and vlan tagging. Or would i be ok just making a class B /20 network and let it ride?
