My client (a small college) has a Windows SBS server running dns, dhcp, etc. There are approx. 50 desktops used by college staff and students.
Additionally, students are allowed to connect to the college's Wi-Fi using their iPhones, iPads, etc. in order to browse the internet.
There is a Netgear DSL modem, a Sonicwall Firewall and 5 CISCO wireless access points throughout the building.
Windows SBS DHCP server is configured to allocate IP Addresses from 192.168.0.50 - 192.168.0.200. Everything else is reserved for printers, ip phones and networking equipment above.
The problem I have is that students using Wi-Fi from their phones/tablets, get allocated an IP Address by the DHCP server and soon after the DHCP server runs out of IP addresses to allocate.
These Wi-Fi clients dont need access to the college's network. They only need internet access.
How can I resolve this issue?
