Ok so my MacBook suddenly decided it didn't want to connect to my home wifi anymore. All other devices such as iphones, androids and ipads are able to connect perfectly. It's strange, I followed a couple things I found online such as: Ran diagnostics on macbook Rebooted / power cycled router Rebooted Mac Disconnected Bluetooth Restarted Wifi Forgotten all networks / deleted preferred networks Changed wifi channel in the router settings Removed my antivirus Deleted some files from a folder somewhere.. /Library/Preferences/SystemConfiguration/ Is there anything else I can try? This is really starting to annoy me. I can't think of what it could be. My router is about 2 feet away from my MacBook Pro and it's a decent one, a Belkin... (I don't know the model off my heart but I bought it new about 3 years ago.) P.S I'm running the latest OS, Sierra.
