Is there a reason why my iOS devices are taking a long time to show the WiFi fan icon when trying to connect to an AP (7372)? I can see it connects right away on the ZoneDirector but the iPhone or iPad takes awhile to show the Wifi fan icon.
We have seen this too but I don't know what causes the problem. It's not just as simple as it needing a valid IP however. When we have an issue where an iPad connects but does not have the icon I have verified that the device does have an IP address from DHCP and it is pingable from both the same and other subnets. My guess is that it makes a test DNS/HTTP request and that request fails initially and it does not retry. Unfortunately even with the network functioning without that icon everything on the device is in offline mode and it does not even try to access the network. The only solution we found is to disconnect from wireless and reconnect.
I have iPads with iOS 11.4. When trying to connect to an AP I get an issue with an Apple ID. Also Not capable to receive notifications in this state in any other WiFi than I could test. I need to talk to IOS support team they will tell the process how to get the latest version of IOS, just need to dial apple id support number and get the solution like this. And having any kind of other problem then get stay with their team always.
