Questionable Wi-Fi problem on MBP: how to analyse it?
Try following in your Terminal:

Manually connect to WiFi

Turn On

networksetup -setairportpower en0 on


Find

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport scan


Connect

networksetup -setairportnetwork en0 WIFI_SSID_I_WANT_TO_JOIN WIFI_PASSWORD


It also shows it is using your Samsung as network provider, so turn it off first then check again if wifi comes on.
