Before asking a question, I will state that I live in Korea.
Yesterday, at school, I used it as a hotspot for one of my friends. The password was '123412341234'. I left him to write it properly.
After I woke up, there was another person connected and all the data on my plan was gone. At that time, I was so embarrassed that I couldn't save the machine's MAC address.
How can I get a record of my hotspot's users log?
