I opened my own restaurant and installed several WIFIs, but then someone from the so-called "Network Supervision Bureau" came and said that I would use the unlimited router they provided.

If he wants you to use it, you can only use his, unless you are relatively powerful.

Otherwise, he will disconnect you from the Internet very quickly.

Because you have installed wifi, you can easily have more than 4 computers or mobile phones on one line. Most places have a limit of 4, unless you pay more to increase the number. .

You buy it and put it there, and then use something else. When you check it, it says it is broken and cannot be connected. Generally, as long as you pay the money, everything else is easy.

The law does not require you to use his router, but he has many legitimate reasons to disconnect you from the Internet.
