Why such a strange scheme? We take a router with support for a usb modem, stick 4g into it and distribute it. What you came up with, if it works after 20 hours of dancing with a tambourine, it will work somehow.
A suitable router is 7000 rubles maximum. We divide by 20 hours. We get 350 rubles per hour - not profitable. Buy cheaper and it will work better even when the computer is turned off.
