iPhone 6 no wifi

How can I retrieve wifi on my iPhone 6?

It used to be able to pick up wifi networks, but for some reason it is unable to now.

I have checked on whether its the wifi itself, but my iPhone 5s is able to pick up wifi networks.

Already tried to reset network settings, this did not change anything.

Also restarted my phone, and still no networks to be found.

Someone PLEASE HELP!
