When Iphone uses WEB authentication and after lock screen is re-unlocked, the condition of WIFI breaking and user off-line will appear. What causes this problem to occur?
 
Phenomenon analysis:
 
 
When Iphone connects with WIFI of WEB authentication, it will send a WIFI connection detection request. After the wireless controller intercepts and captures the detection request, it will redirect to authentication page. And for this process, Iphone will take this WIFI as a regulated WIFI.
 
For Iphone, the authentication page will be popup automatically to authenticate WEB when user connects with WIFI. And after user locks the screen of Iphone, Iphone system will detect WIFI flow automatically. Because the screen has been locked without flow and Iphone takes this as a regulated WIFI, it will break the connection with WIFI automatically.
 
Consequently, the appearance of this problem doesn’t mean the fault of equipment operation. Actually, this problem will occur when all Iphone adopts web authentication method to surf the internet. And for mobile phone with Android system, this problem will not appear when adopting web authorization.
