There is an ISP in my town that connects to my phone all the time, but it wants to sign in to be used. It is not my ISP so that all I get is my Wi-Fi blocked.
There are many spots from the same ISP in town, because a couple of ISP give their customer a router with two Wi-Fi outputs, one private, normal, and another one open for their customers use with their site password wherever they exist. One of them (not my ISP) sticks to the devices, so I get blocked in many areas.
I have tried to change autojoin=1 to autojoin=0 on
/data/misc/wifi/wpa_supplicant.conf, but that didn't do anything. This file also mentions another one,
ctrl_interface=/data/misc/wifi/sockets. Will that control I need be here?
I am almost sure there will be a way to disallow a device from connecting to a specific Wi-Fi, but I don't know how. Maybe somebody can help me and teach me how, please.
