Jan 26, 2015 2:06 PM in response to edmuseerby Lawrence Finch,Troubleshooting: On one (or more) of the phones, after attempting to connect, go to Settings/WiFi. Tap on the i to the right of the network name and look at the IP address. If it begins 169.254... this means that the WiFi router did not assign an IP address, so the phone created an "ad hoc" address. If this is what you find this is a router problem, not an iPhone problem.
Start by rebooting the router. Sometimes this correct the problem by restarting the DHCP daemon in the router that assigns IP addresses. Beyond that you can try updating the firmware in the router to the latest version.

Jan 26, 2015 2:13 PM in response to edmuseerby Lawrence Finch,But you still don't see the "fan" icon in the status bar? Does your network have MAC filtering, and are the affected phones whitelisted if it does? Do you get any error message on the phone (e.g., "could not connect to network")?

Jan 26, 2015 2:25 PM in response to Lawrence Finchby edmuseer,When I enter the SSID and then the key to connect, it appears to connect and be using it. But the fan icon never appears in the upper left. No MAC filtering is configured. All Android devices work without any trouble.

Jan 26, 2015 2:28 PM in response to edmuseerby Lawrence Finch,So the SSID is hidden? That shouldn't be a problem. Can you monitor the network and see if the phone is using WiFi? Or ping the phone's IP address on the network?
Note, BTW, that an iPhone will only use WiFi when the screen is open or the phone is connected to power. WiFi is turned off 30 seconds after the phone goes to sleep to preserve battery. But this doesn't seem to be your issue.

Jan 26, 2015 2:44 PM in response to Lawrence Finchby edmuseer,SSID is not hidden. I should say, when I tap on the SSID name in the WiFi list. MAC addresses are showing up as connected (both Apple and Android phones) in the WiFi router. I am able to ping the IP supplied by our network (Wireless router is configured as access point and dhcp is turned off). I have 3 iPhone users with 8.2.1 and all exhibit the same behavior.

Jan 26, 2015 2:49 PM in response to edmuseerby Lawrence Finch,Can you tell if the phones are using WiFi with Wireshark or other network monitor?
We've about reached the limit of my knowledge here. You might want to contact Apple's Enterprise support center.

Jan 26, 2015 2:50 PM in response to edmuseerby Lawrence Finch,Another test is to turn off Cellular Data on the phone and see if it still has connectivity.

Jan 27, 2015 7:08 AM in response to Lawrence Finchby edmuseer,When I turn off cellular data, the fan icon shows up in the top left as well as the cellular provider.
-
Jan 27, 2015 7:12 AM in response to Lawrence Finchby Lawrence Finch,The cellular provider's name will always appear, because it provides the voice service. Can you post a screen shot showing the top bar when cellular data is on? To take a screen shot press and release the HOME and SLEEP buttons at the same time. You can then email the image to yourself.

Jan 27, 2015 7:13 AM in response to Lawrence Finchby edmuseer,Do you mean cellular data turned on and wifi icon missing?
-
Jan 27, 2015 7:15 AM in response to edmuseerby Lawrence Finch,Yes, I want to see why the fan may be missing, and what is in its place. I'm working on the hypothesis that there isn't enough room in the status bar to show it.
