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?
- 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 — feel free to give them to me. A greater amount of access points or a better router is not a problem to buy.
