We have Cisco Controllers and AP for our wireless network. We also have a seperate Guest Network VLAN with no SSID. The runs though the Controller to a seperate Router - it's Network Prosafe Router. We have DHCP set up on the router however, the DHCP stop giving out addresses intermittently. We have over 2000 IP's in this router however, we don't think this is a good setup considering the Guest Network keeps going down. Sometimes we can wait it out other times we reboot the router. My boss came up with the Idea to create a DHCP server and attach it to the guest network. That seems simple enough in theroy but in practice I'd have create some type of domain or can this be done in a workgroup. I don't want to have to create a guest domain and I'm not sure I can even do that because of AD. So is this even possible?
Also, how could we handle a splash page for a guest network?
