There is an issue with iOS 6 and later whereby a WiFi connection can not be made if an internet connection is not present.
If you try to connect to a WiFi network that doesn't have an active internet connection, you may find a landing/help web page appear (depending on your router/access point).
With iOS 6 and above, leaving this page causes your Apple device to disconnect from the WiFi network you were trying to connect to.
To fix this issue:
Select the smallarrow next to the name of your WiFi network
Under ‘HTTP Proxy’select ‘Manual’. Then in the server address type ‘a’ and in the port type ‘1’.
This diverts all website data to a non-existent address, and stops the Router/Access Point’s landing/help web page from appearing.
Then press the ‘Wi-Fi’ button to navigate back. Then select your WiFi network again to join it.
You’ll need to repeat this for any wireless networks you want to use that don’t have an internet connection. For example if you have a wireless router broadcasting 2.4Ghz and 5Ghz WiFi, this workaround will have to be applied to both
