Macbook will not connect to my home WiFi
I have an interesting situation. I have home WiFi set up in that is working fine - I know this because my iPhone connects to it without any problems. My Macbook always connected fine as well up until a week ago and all of a sudden will not connect to it. There is an exclamation point over the WiFi symbol. The WiFi setting is definitely turned ON and I can connect to my hotspot, but for some reason it will not connect to the home WiFi option. I have a brand new Macbook Pro and have done all of my software updates offered. My iPhone still connects to the home WiFi with no problems, so I know it is not a router problem.
Is there a setting on my MacBook that would prevent me from connecting to just this particular WiFi that could have gotten messed up accidently?
