I needed a WIFI signal booster because I had a heater controller that was constantly disconnected from the network. But why should I buy one when I have an ESP01 in the drawer, Tasmota also has a "rangeextender" version. I took the ESP01, loaded the rangeextender program, packed it with a 3.3V stabilizer and some capacitors in the housing of a 5V adapter and the signal amplifier was ready. I just had to set it up.

ESP-01

Load program:

Using a previously used circuit, we navigate to https://tasmota.github.io/install/ where we select the "Tasmota Rangeextender (English)" program.

After loading the program, you only need to set a few small things, and you already have the WIFI signal rangeextender.

It must be connected to your existing WIFI network, I have already detailed this in the second part of this article. It can be viewed here .

If this is done, navigate to the Console page and set the SSID, password and other functions.

(SSID must be different from existing WIFI.)

Setting:

The setting commands are written in the "Enter command" field and confirmed with the enter key, one by one.

RgxSSId MY_OTHER_WIFI
RgxPassword MY PASSWORD
RgxAddress 192.168.10.1
RgxSubnet 255.255.255.0
RgxState ON

The setting interface of the device is available on the network at the set IP address if you connect to the device itself. If we want to access it from the network to which it is connected, we must use the IP that it received via DHCP or that we set for it statically.

With these settings, we still need to set a root rule in our router (not all routers can do this).

The root rule is needed so that we can reach the devices connected to this device from our original network to which the device is connected.

If you have a simpler so-called SOHO router, you must use the so-called NAPT mode. This means typing one more command into the console:

RgxNAPT ON

In this case, port forwarding must be set for the connected devices. Tasmota details more here.

The WIFI signal booster uses DHCP by default and assigns IPs to the devices connected to the network, so it should not be in the same IP range as our existing network.

I recommend it especially for connecting IOT devices, its speed is not high. I measured a maximum of 4MBps download and 4Mbps upload, in very ideal conditions. Don't ask for too much.

Final result:

It was practically free, it fits the purpose.
