Disable Internet access detection of WiFi networks?

Question

In fact my WiFi DO HAVE Internet access, but for some reason it keeps telling me I don't and won't automatically reconnect to it. Now I have to manually reconnect every time.

So, is it possible to disable Internet access detection of WiFi networks?

I'm using CyanogenMod 12.1.

I've tried disabling captive portal detection, still no luck.

Answer 1

If your device is rooted, and have a firewall installed, you need to grant network access to Setup Wizard app (ID # 1000), so it can resolve the Google look up. I verified this in my situation by turning off and on my firewall, and checking the firewall logs.

I did not mess up with any editing of the captive portal settings. If you have the same problem, you have to forget the Wi-Fi networks in order for the SSID to be cleared. Once you grant network access to the Setup Wizard app in your firewall, the admiration point will disappear.

Answer 2

If you open the menu in the wifi network list, you should be able to select 'Advanced' for the advanced wifi settings. Then try disabling the checkbox 'Avoid poor connections'. Even if Android thinks your wifi is too slow/not good enough, it should still connect and work like it should.

Keep in mind that disabling the checkbox will cause your device to try maintaining a connection to your router, even if the reception is very weak or the throughput is very low, which can affect your battery life.
