I am trying to setup for a massive event where we expect to have 1000 people. I am trying to setup a BR200wp as the DHCP server and router. I am going to configure the guest network as a 172.16.0.0/16. On the subnetwork configuration screen when I click save I get the error "
Address Pool cannot exceed 512".

What am I dong wrong? This error has then prompted a second question. Should I not use a BR200 as a the DHCP server and router?

I would say there is a memory restriction and that your pool can not exceed /23

you might want to use a dedicated dhcp server or two for such a large pool

from experience trying to use a switch or a router as dhcp server, is just not scalable. Even if you managed to configure a large pool, you would find connection issues when all users try to gain access at the same time.

Thanks Andrew for the speedy response. The guest network at this event is a luxury. We really only need the network for a few booths. I talked with my boss and I got him to veto the guest network idea.

I still wish I could do it but I don't think 1BR200 router, 5 AP330's, and a mac mini running as a DHCP sever will cut it.

I'm reminded of iphone 4 demo.

CWAP says it was due to near far issue.

It's my latest adventure

They mention the event and say that it was an example of near far issue.

but not this one

Abe your most likely not going to have 1000 users connected at 1 time, maybe a short dhcp lease might be a feasible possibility for guest access and most guest will most likely only be using webmail or applications like that. Really depends on the event and setup.

usually in HK when I attend events with 500+ users and wireless at the venues is always sluggish.
