One day, when I came back to work, I discovered that the internet had disappeared. The devices displayed a page with a hardware scheme requesting the provider to check the connection settings. I checked it did not help. I made an application. The next day the brigade arrived - began to dig in the shield and on other floors in search of the reason for the lack of signal. As a result, it was established that the next day the neighbors on the upper floor connected to the internet (from the same provider), and the installer, in order not to bother laying wires, just took and pulled out of the shield my apartment, inserting instead the cable of the apartment of new happy subscribers.
