Modem
What should I do when a provider can not solve the problem of accessing the network from your beloved granny? But the older generation also wants to be in touch and comprehend the world without leaving home. Our recipe was shared by our reader. Under the cut, a short story about how to assemble a wi-fi transmitter from improvised means. From his face and tell.
I have a DSL Internet at home, and my grandmother, who lives a kilometer of direct line of sight from me, can not connect it. The provider simply does not have free resources. Therefore, it was decided to assemble the wi-fi transmitter by its own efforts, fixing it on the base of the house.
As an enclosure an electric shield was used. It was equipped with a DSL modem TP Link and an access point wi-fi D-Link dwl-2100ap.
The power was increased to 1 W using the engineering menu. I constructed a directional antenna using an ordinary beer can. The main problem is power supply, since it is dangerous to conduct a cable with a voltage of 220V directly through the roof. In the winter there it is wet, and besides this, the wires can chew the mice. It’s not far from the closure and the fire.
As a result, it was decided to reach the roof of the 12th from a reliable uninterrupted power supply for 8 amperes, which can save from short circuits. He installed it inside the system unit. But the modem and the access point require 5 volts supply, and the total current is 1.5 amperes. I tried to make a DVR from the standard charging, where 2 amps are indicated, but it was terribly overheated.
The solution was found on the Internet. Thanks to this scheme:
From the elements of the computer block it was possible to collect this:
The scheme has been working reliably for several years and is not heated. And the granny has a stable signal.
