Is it possible to get wifi signal strength in ios

Question

I want to check WIFI signal strength to display some kind of message for weak WIFI signal.

I fount that it is not possible in iOS 8 and older.

Is it possible to get wifi signal strength in iOS 9? and if answer is yes then How?

Answer 1

It is, but you need permission from Apple. Once Apple allows you to use the HotspotHelper framework, you'll be able to create profiles with the hotspot helper entitlements. Check this post: How to get Wifi SSID in iOS9 after CaptiveNetwork is deprecated and calls for Wifi name are already blocked

Answer 2

Yes , it is possible in iOS 9.Look into NEHotspotNetwork

Answer 3

Register your app as Hotspot helper. (forums.developer.apple.com/message/30657#30657)

#import <NetworkExtension/NetworkExtension.h>

for(NEHotspotNetwork *hotspotNetwork in [NEHotspotHelper supportedNetworkInterfaces]) {
    NSString *ssid = hotspotNetwork.SSID;
    NSString *bssid = hotspotNetwork.BSSID;
    BOOL secure = hotspotNetwork.secure;
    BOOL autoJoined = hotspotNetwork.autoJoined;
    double signalStrength = hotspotNetwork.signalStrength;
}
