Cheap Wifi Routers

In the comments I was asked why for such an elementary action I did not use a regular WiFi repeater. Well, today we’ll figure out how such a thing works, what are its pros and cons.

Theory As I said in a previous article, the use of PLC was due precisely to the crap Wi-Fi broadcast and the transfer of the “mother” point to the 5GHz range, in which the wall penetration was greatly worsened.

The scenario for using Extenders is somewhat different. Instead of using the “unblocked” channel “inside the outlet” to route the network where it is impossible to spoil the walls and the floor with cable laying, we use the trivial space of the apartment / house / office: take the point where Wi-Fi reception is so-so, the point, where is the router, and approximately in the middle we hang Extender or Repeater or call it what you want. He takes Wi-Fi where the reception is still strong enough and repeats the signal to where the “native” source no longer finishes.

In this case, the repeater operates in the same channel as the source, and, as a result, slightly reduces the overall speed for the mother access point and for itself. The ideal conditions are “direct radio visibility” between the point of reception of the signal of interest to you and the repeater, repeater and router.

Practice As an example, take the Upvel UA-322NR Wi-Fi repeater. In Yulmart, this particular manufacturer is not available now, but there are many other options for every taste and size of the wallet. I do not think that any TP-Link or ASUS will differ greatly in characteristics or capabilities. The general principle of operation is approximately the same, as well as the scope of delivery.

The box is neat, everything is in Russian and perfectly localized, even a child will cope with the installation. Inside – the device itself, a small ehternet-cable, bright and clear instructions for initial setup and miniCD with additional information and software.

The gadget itself, in fact, consists of an Ehternet port, a WPS button, a small “pin” Reset button, an indicator of the reception level and a socket for the outlet.

After the initial setup, the gadget was moved to a room that needed to be “lengthened”, but there the signal level (and, accordingly, the speed of work) were at the minimum available values, and there would be no effect from the extension of such a weak network.

Therefore, experimentally, in an adjacent room with a normal reception level, a position was found in which the signal level for the repeater was at a sufficient level, and at the point where the Internet was needed, everything started up at normal speeds.

Since then, the device worked for six months without interruptions, and after a while, a wired digital TV receiver was added to it: since the Ethernet port can be used not only for setting up, but also for distributing Wi-Fi to those devices that cannot enter the network via wireless channel, but have a regular Lan port.

We measure the speed In order not to be unfounded, I quote the graphs. This is how Wi-Fi worked before installing the repeater in the far rooms:

As you can see, the Internet is barely a soul in the body, but does not smell of speed. With the installation of the repeater in the desired room, the reception level has increased significantly, but the speed – for obvious reasons – no, since the repeater was repeating an already pretty withered signal. But after the repeater was rearranged in the “right” place, selected empirically, the signal quality increased, the speed could be called acceptable.
