How do I turn gray wifi icon to blue? I have been searching for answers and some suggestions doesn't seem to work.  I can connect to WiFi but I am not able to use it, (Facebook, Play store, Etc.) because the WiFi icon seem to turn into gray. What will I do??
This, at least for me, happens when my device connects to Wi-Fi, but with wrong parameters. I fix this by entering the Wi-Fi settings, choosing "Static IP" instead of "DHCP", and then editing the network parameters manually, like this:

These settings may be different on your router, so check that if it isn't working.


IP adress: 192.168.1.xx (replace xx with any number, avoid 2, 3 or 4, because there may be devices already connected with that adress)
Gateway: 192.168.1.1
Prefix lenght: 24
DNS1: 8.8.8.8
