My wifi started to go slow and I notice that my WiFI: keeps on changing from "on" to "Looking for Network". I also could not connect to "App Store". Please help.
MacBook Pro, OS X El Capitan (10.11.5)
This is normal and expected behavior in OS X. You can run a speed test and check your connectivity.

Thank you for your reply. I have another problem. I can not connect to the apple store.
Can you connect to the Apple store if you have a wired network connection?
