My laptop connects to every wifi accept my home wifi. Sharing mobile data from my phone doesent connect as well if it is password protected. Open wifi works. Wifi is secured with wpa2. Even sharing cabled connection from my windows pc works (again wpa2 secured). Any reason that this is happening?
Cannot connect to certain wifi

Watch the journal while try to connect:
