2 networks on 1 wifi router?

Posted 28 June 2013 - 07:37 AM

Okay, so my company is about to have a convention in a week and our IT guy is out for the next 3 weeks, so I am left to this task. I was originally hired as a programmer, but I'm the closest thing we have to an IT specialist..

Anyways, as stated before, we are about to have a convention with probably over 1,000 people coming. We want all of our customers to be able to connect their wireless devices to the internet, while not being able to access our main network. We only have 1 wireless router at our disposal, and 1 wireless Access Point. The Access Point is where they will be connecting. Is there any way to do this with only these two pieces of hardware?

Is This A Good Question/Topic? 0

Think of it like any small business that has 'free wifi' but doesn't want peeps on their network.

The magic google word you want is, probably, VLAN.

All network equipment comes in two distinct flavors: profession and home user. The home user wifi routers often allow you to isolate wifi traffic from the rest of the network. The business level will usually make you work for it, at which point you might find it easier doing VLAN isolation on the port the wifi device is plugged into. Setup is, unfortunately, pretty vendor specific.

Most routers will have a guest network feature. so that would solve your first problem.

but if your having a 1000 people potentially connecting that will catastrophic.
1. only 255 ip address can be assigned
2. most people have about around 23 mbps of service so thats about 25 people online.

good luck

That would be called a class C network. The simple, uses the last octal, /24 layout you see on most home routers. Networks are not limited to that size, though 16,777,216 addresses per network is a logical high end.

My point exactly. There are three different private network address ranges, the Class A 10.0.0.0, Class B 172,16.0.0 - 172.31.0.0, and the Class C 192.168.0.0. See this link: Address Classes. Even simple home network routers should be able to use any of he above private networks.

Mikrotik can do this fairly trivially by broadcasting multiple network SSIDs. I believe it was virtual SSID but I don't remember offhand. Those things can do some serious power networking if you wield them correctly, but the community has a tree up their collective tails so be warned.
