How to support more than 500 users at one time on a WiFi network

What I want to achieve is to serve an HTTL server on a LAN. Let's call it a server and give it the address 192.168.0.2. I would like to let people access this server via the browser on their mobile devices but only if they are connected to the LAN via WiFi (they can not connect from outside the LAN area like via WAN or something).

Normally it would not be a problem unless I want many people to connect at the same time. I've heard that the maximum amount of users that may connect via WiFi is 256 (including a server and router) with the subnet mask 255.255.255.0. Changing the subnet mask may increase the amount of users (is that true?) but in reality more than 20-30 would halt the router.

Here come the questions:

Are there routers that allow simultaneous connection of more than 200 users?

Will changing the subnet mask give me the opportunity to have more than 255 clients in the network?

Does WiFi radio bandwidth allow so many users at the same time?

Can it be solved via multiple access points? I mean one router and 3-5 or more access points?

Is it possible to have a DHCP server give users IP addresses from 192.168.0.1 to for example 192.168.3.255?

Additional info:

Security issues don't concern me; there may be no encryption for logging into the network if that makes the problem easier to solve.

If there are more expensive but better solutions Ã¢Â€Â” feel free to give them to me. A greater amount of access points or a better router is not a problem to buy.

And if you are really expecting 500 users on your network, maybe look at professional gear, not home routers. That will also give you the tools and firmware to set up something like this with multiple APs with manageable effort.

Your questions answered 1 by 1

YES - I'm not making product recommendations so simply search using your favorite search engine. Common brands are Ruckus, Cisco, Aruba, Zyxel etc. etc.

Is changing subnt mask give me the opportunity to have more than 255 clients in network?

YES - see more below.

Does wifi radio bandwidth allow so many users in the same time?

YES and most decent APs have features to manage bandwidth.

Can it be solved via multiple access points? i mean one router and 3-5 or more access points?

YES, that would be the normal way to do it. AP's are limited to a maximum number of clients due to wireless protocol limits, however routers scale much higher, so 1 decent router will be sufficient for 500 users. Number of AP's depends on the actual AP(s) you buy.

Is that possible to have dhcp server to give users ip addresses from 192.168.0.1 to for example 192.168.3.255?

YES - very simple - a subnet mask of 255.255.255.0 (means the last part of the mask can give 0 to 255 numbers, for a total of 256). Out of that the .0 and the .255 are not used because of how IP routing works, so you have 254 usable. Then one gets used by the gateway leaving you 253 available client addresses.
When the subnet mask is 255.255.0.0, that means a total of (256 x 256) = 65535 IP addresses are possible and after removing the .0.0 and .255.255 and one more for gateway you have 65532 available.

Since you are in a subnet behind a firewall the only limitation I can think of will be placed by the router or AP (home ones can be typically limiting to the last part at 0, but even in the home market not all devices impose the limit). Keep in mind, the subnet mask is simply an IP addressing related "limit" and in private networks, it is essentially an arbitrary limit.

Opening up the subnet mask is a great way to get your radio completely swamped by broadcast traffic. Higher-grade APs will let you use much smaller subnets to reduce this problem.

I've heard that maximum amount of users that may connect via WiFi is 256

That number is close, however, they will be limited as to the connection speed they are are able to obtain. The rule of thumb is 45 devices.

For example, a WiFi router rated at 300 Mbps with 250 devices connected will be limited to an average of average 0.8 Mbps.

There are a number of practical limitations:

Practical Limits of Wi-Fi Network Scaling

Connecting 250 devices to a single WiFi access point, while theoretically possible, is not feasible in practice for a few reasons:

On home networks, all devices normally share a single internet connection. The performance of clients' access will start to degrade
as more devices join the network and start using it simultaneously.
Even just a handful of active devices streaming video or downloading
files can quickly max out a shared internet link.

Access points overheat and stop working when operating at extreme loads for extended periods, even if handling only local
traffic and not accessing the internet.

Having a large number of WiFi clients concentrated in close physical proximity, like a home or office building, generates
significant wireless signal interference. Radio interference among
WiFi clients degrades network performance (due to frequent
re-broadcasting of messages that fail to reach their destination) and
eventually causes connection drops.

You can get around these limitations by adding adding additional routers or access points:

How to Maximize Your Network's Potential

Installing a second router or access point on a home network can
greatly help distribute the network load. By adding more access points
to the network, effectively any number of devices can be supported.
However, this will make the network progressively more difficult to
manage.

Source Wireless Network CapacityÃ¢Â€Â¦How Many Devices Can Connect to my WiFi Network? - Actiontec.com

And:

A general rule of thumb is to limit the number of simultaneous
connections on your home network to 45. However, the specific number
is going to vary widely depending on what each of those devices is
doing. For example, downloading MP3s, ISOs or other large files
requires much more bandwidth than checking email or simple Web
browsing. Likewise, if the network is hosting Web, FTP, or Gaming
servers, the recommended limit for the number of network connections
may be much lower.

Theoretically, you could even use a class-A network (10.0.0.0 netmask 255.0.0.0) for your WiFi. That would give you enough ip-addresses for your users. But that will not be practical.

In practice though, you will need to use an enterprise-grade solution. Most home-routers stop at round 30 users (dual band Netgears at 64, etc..) and you will have to make a routed network with more that 16 access points to make your server available.

Enterprise-grade solutions come with a price-tag. For example, an Aruba Wireless LAN controller with a few access point is easily round 10k EURO (convert to your local currency) and requires quite a bit of knowledge to set-up. Cisco is even more expensive.

Meraki is (just a bit) less expensive and offers a "Cloud" solution that is relatively easy to use, but it may not match your requirements.

The number of access points that you need also depends on the protocol that you use:

Protocol Bandwidth #clients per AP
802.11b 600 kbps 13
802.11g 600 kbps 43
802.11n (2 Spatial Streams) 600 kbps 273

(that is Cisco, but other vendors should be comparable)

If you are going to use a stack of home-routers, than you also have to look at interference. Your 16 routers will have a limited number of bands and they will slow down the connection with other routers. Not also, that a stack of 16 home-routers is also not very cheap.

If you're going to use an enterprise-grade solution, DHCP will be incorporated in that. But get some expert help before deciding on the architecture for these size of networks.

Why would i need 64 home routers? If home router lets me connect 30 users and i want to do it for 500 users - 500/30 is about 17 home routers.

It was perhaps a bit of an exaggeration. The point is that the home-routers will come at a price-tag and will produce a lot of interference. (changed 64->16 in the answer)

There are a few different limitations at play here. The access point may indeed be able to only accommodate so many users at the same time before the signal degradation is so big that it randomly starts dropping users. This can be solved by using multiple access points, where each can server different users. Also, cheaper access points or routers may not be able to handle many users at the same time, where more expensive routers/access points can hold up to 255 users.

The second is going to be handing out IP Addresses. In order for devices to communicate over the wifi network/lan network, each device must receive an IP Address. This means that the DHCP server must set a network big enough to hand out more than 255 ip addresses. That automatically means, that you have to either create a network with a larger subnet (class B or higher), or divide each segment into vlan's so that they can have their own inner network, which means that people from group A cannot see and communicate with people from group B, etc, but all could access your webserver if you set it up that way. The 2nd option mentioned here is going to be trickier to setup and cannot be done unless you have capable hardware. That can be as simple as multiple routers with wifi capability, each serving up to 255 users, and their wan port linked to a network behind where your server resides.

Also, better enterprise hardware can do this on just one device, but is harder to setup.

Therefor the easiest method is going to be one router with a bigger subnetmask to create a Class B network with more than one Wifi point.

If i understand correctly, one router which serves different subnet mask than 255.255.255.0, serves more than 256 ip addressess. Now i connect APs to router via wifi/ethernet and each AP serves 255 ip addresses for users 255 users. Does each AP have different SSID? Or all have the same and if limit of users on AP is achieved it doesnt allow connecting anymore, leting other APs to work?

It depends on your Wifi if different SSID is required or not. It is not strictly necessary, which will make all AP's be seen as one, but with different SSID's, you can allow people to select to what AP they should join. AP's that work as a mesh will always have one SSID as you then basically assign a big area with one WIFI using many AP's.

Connecting 250 devices to a single WiFi access point, while theoretically possible, is not feasible in practice for a few reasons:

On home networks, all devices normally share a single internet connection. The performance of clients' access will start to degrade
as more devices join the network and start using it simultaneously.
Even just a handful of active devices streaming video or downloading
files can quickly max out a shared internet link.

Access points overheat and stop working when operating at extreme loads for extended periods, even if handling only local
traffic and not accessing the internet.

Having a large number of WiFi clients concentrated in close physical proximity, like a home or office building, generates
significant wireless signal interference. Radio interference among
WiFi clients degrades network performance (due to frequent
re-broadcasting of messages that fail to reach their destination) and
eventually causes connection drops.

You can get around these limitations by adding adding additional routers or access points:

How to Maximize Your Network's Potential

Installing a second router or access point on a home network can
greatly help distribute the network load. By adding more access points
to the network, effectively any number of devices can be supported.
However, this will make the network progressively more difficult to
manage.

And:

A general rule of thumb is to limit the number of simultaneous
connections on your home network to 45. However, the specific number
is going to vary widely depending on what each of those devices is
doing. For example, downloading MP3s, ISOs or other large files
requires much more bandwidth than checking email or simple Web
browsing. Likewise, if the network is hosting Web, FTP, or Gaming
servers, the recommended limit for the number of network connections
may be much lower.

I've heard that maximum amount of users that may connect via WiFi is 256

That number is close, however, they will be limited as to the connection speed they are are able to obtain. The rule of thumb is 45 devices.

For example, a WiFi router rated at 300 Mbps with 250 devices connected will be limited to an average of average 0.8 Mbps.

Theoretically, you could even use a class-A network (10.0.0.0 netmask 255.0.0.0) for your WiFi. That would give you enough ip-addresses for your users. But that will not be practical.

Meraki is (just a bit) less expensive and offers a "Cloud" solution that is relatively easy to use, but it may not match your requirements.

The number of access points that you need also depends on the protocol that you use:

Protocol Bandwidth #clients per AP
802.11b 600 kbps 13
802.11g 600 kbps 43
802.11n (2 Spatial Streams) 600 kbps 273

(that is Cisco, but other vendors should be comparable)

If you're going to use an enterprise-grade solution, DHCP will be incorporated in that. But get some expert help before deciding on the architecture for these size of networks.

Why would i need 64 home routers? If home router lets me connect 30 users and i want to do it for 500 users - 500/30 is about 17 home routers.

It was perhaps a bit of an exaggeration. The point is that the home-routers will come at a price-tag and will produce a lot of interference. (changed 64->16 in the answer)

Also, better enterprise hardware can do this on just one device, but is harder to setup.

Therefor the easiest method is going to be one router with a bigger subnetmask to create a Class B network with more than one Wifi point.

If i understand correctly, one router which serves different subnet mask than 255.255.255.0, serves more than 256 ip addressess. Now i connect APs to router via wifi/ethernet and each AP serves 255 ip addresses for users 255 users. Does each AP have different SSID? Or all have the same and if limit of users on AP is achieved it doesnt allow connecting anymore, leting other APs to work?

It depends on your Wifi if different SSID is required or not. It is not strictly necessary, which will make all AP's be seen as one, but with different SSID's, you can allow people to select to what AP they should join. AP's that work as a mesh will always have one SSID as you then basically assign a big area with one WIFI using many AP's.
