How to remove unwanted WiFi networks from my list?
Hello, I have unwanted (unsecured) wifi networks appearing in my network list - ASUS/ASUS 5G in the screenshot below. When my wifi is off my kids can connect to them. I tried what other people said Network / wifi / advanced / click on - to delete the unwanted networks, it doesnt appear there anymore, but it keeps appearing on my network list... Any tips?
