Wondering if anyone has seen similar issues.
We are experiencing an issue with Iphones connecting to a guest SSID with "guest" Captive Portal authentication. The platform is two 6000 based controllers running AruabOS 6.1.3.4 in an VRRP configuration.
When an iphone device connects to the guest network some are experiencing intermittent issues where they will associate to the ssid successfully, however from there users can't get a captive portal login. Upon further investigation it appears that when this occurs, the devices are not recieving a DHCP address (which is assigned from the controller). During testing, other devices (standard pc's, macbooks, etc.) all connect fine. Resolution is to either "Forget this Network" and reconnect the device or reboot the device, which so far in all cases solves the problem temporarily.
