iOS 10 using WiFi Networks without Internet Access

I work in the live entertainment industry where we often use iPads etc. for wireless remote control of equipment and devices.  On these "adhoc" wireless networks, we most often do not want to connect our access points or wireless routers to internet access.  Up until the release of iOS 10, this has not been a problem for connection because we just connect the iPad to the network using a static IP in the subnet range of our console, projector, or other device.  Since installing iOS 10.0.2, this way of connecting to the network is no longer working.  When trying to connect to the network we now get an "!" on the network connection and we are unable to access our devices directly.

Is there a way to force the iPad onto a WiFi network that intentionally does not have internet access without having to setup a client portal on the access point or router?

Are you saying your wireless devices can't communicate anymore? Did you verify all devices are in /16 subnet? That's 255.255.0.0

All devices are in the same subnet and would communicate correctly in iOS 9.  Since iOS 10, the communication is blocked seemingly due to the "no internet connection" as  seen in the attached photos.

Have you tried resetting network on the iOS 10 device and re-entering static IP then reconnecting? If nothing works, your only option is to wait for iOS 10.x update. Sorry, I'm out of ideas.

Since I know a lot of use cases out of several industries that use these kinds of features where they connect clients to a local WiFi hotspot device without any internet Connection I really(!) hope Apple will release a fix in the next update!!

I'm not original poster, but I just updated to 10.1 and am still seeing OP's described behavior.

One note: I am using DHCP on the WiFi network, and the iPad appears to be receiving an IP address correctly.

Try adding a router and DNS address.

I can replicate this on my iOS device by adding a valid static IP but no router or DNS server. Add those and the error gets away.

I can confirm that adding a valid static IP, router and DNS address does make the "No Internet Connect" label go away in Settings-->Wi-Fi.  Additionally, with that set, kSCNetworkFlagsReachable on IN_LINKLOCALNETNUM is true (in DHCP or without router/DNS set it is false).

However, I'm still unable to open connections (Socket, HTTP) to the router, even with the Static IP.

Did you confirm that connections were possible via Static IP/Router/DNS?  Or just that iOS removed the "No Internet Connection" warning?

I've confirmed the behavior continues in 10.1.1

Hopefully you've chosen to also report or address this issue to the Apple Feedback

section most appropriate to a likely resolution; as a note, I have sent a link to this ASC

discussion and hope that someone there can look into it.

Seems like too good of a feature to not re-enable for special purposes as noted here.

Good luck & happy trails!

Greg contacted Lantronix Technical Support, where I am a Senior Technical Support Engineer about this issue when using an iPad or iPhone running iOS 10.x to connect to a device using a Lantronix xPico WiFi as its WiFi interface.

I confirmed the behavior from an iPhone 6s+ running iOS 10.1.1.

I tried LACAllen's work around, setting up a static IP address and using the xPico WiFi's IP address for the Router and DNS settings. This caused the "No Internet Connection" warning to disappear, and allowed me to open the xPico WiFi's web configuration interface, and also to open a TCP connection to the xPico WiFi's serial interface, which listens on TCP 10001 by default and get bidirectional communication through the serial interface.

I've submitted a request to populate the Router and DNS fields from the xPico WiFi's Soft AP DHCP server in a future version of firmware.

We also request that Apple provide an option in a future version of iOS to revert to the iOS 9 behavior for stand-alone WiFi devices that do not require an Internet connection.

Hi. If you don't contact Apple more formally, you should at least report this here https://www.apple.com/feedback/ipad.html.

I'm having the same issue with my iPhone in iOS 10.2. I'm trying to connect to a OBD-II port scanner while using my iPhone's cellular data connection for internet. This used to work by just doing a static connection where I would enter the IP Address and Subnet Mask and nothing else. But now the iPhone won't connect to the scanner's network unless I use DHCP, which cuts my iPhone off from the cellular data connection.

I have the same issue with a Silverlit Xcelsior drone. I have tried to solve it by using static IP address as recommended. For the values for IP address, Subnet Mask and Router, I just re-entered the values that were shown when DHCP was selected. However, there was no value for DNS, so I have no idea what value to enter there. Any suggestions?
