In my office we use Wi-Fi for mobile network. I feel that one of my office staff disconecet the Wi-Fi connection from my phone.is I want to know is this possible. If yes then give me a solution to deal or protect my phone
Manually set your phone up with an IP that is unlikely to get used by your staff. My DHCP range is 192.168.0.10 to 192.168.0.254 so I just use 192.168.0.9 if I want a device to have it's own IP.
