We have a Linksys/Cisco E1500 v1 wireless router that as an AP and worked without issue. It had the latest firmware and the router was given an IP address and DHCP was disabled. We setup the guest network and we were able to connect to it however it would not prompt for the password. No matter the device/OS (tablet, phone, computer, et cetera) when you opened a web browser it would fail even though it did get a 192.168.33.X address. You had to manually go to 192.168.33.1 and it showed the Cisco Connect password page...most of the time. We ended up upgrading to DD-WRT which had it's own issues, but how can we solve this?
