Esp8266 Wifi Repeater Bin File Download

Raspberry Pi can run Linux which comes built-in with router and Wi-Fi drivers. ESP devices (and popular frameworks thereof) do not come with routing code. The Wi-Fi repeater code that exists will give you maybe 2 megabits per second.

With the WiFi Repeater project there is one main network on one interface and a WiFi access point network that wifi-repeater creates on a another interface. The wifi-repeater network is in shared mode (enabled Internet connection sharing). You have an esp device on the wifi-repeater network that you would like to be reached from the main network. The common way to solve this is through port forwarding with iptables, e.g. Port forwarding + shared connection with Ubuntu - Super User.

That said a problem is that the IP address of your esp connected to the wifi-repeater network will be unknown when the wifi-repreater container starts - it is assigned dynamically. NetworkManager does not provide any API in helping with this: like in notifying when something connects to the spawned access point.

One possible way to solve this is to implement another container in host networking mode, which will scan periodically for your esp on the AP network and when found will apply the necessary forwarding rules and possibly notify other devices on the main network. It is definitely something that can be accomplished, but unfortunately the way the NetworkManager API is structured does not allow this to be added to the wifi-repeater project itself and will need some custom coding on your side.

I use an ESP32 to get some binary sensors for HA. I have configured this ESP32 on my wifi network and it works.

Problem, the installation location of the ESP32 is too far from my wifi network and I need to extand it. So I use another ESP32 to make a wifi repeater (GitHub - martin-ger/esp32_nat_router: A simple NAT Router for the ESP32).

The repeater is also working fine. I can connect my phone to the generated AP and I have internet access and local network access.

So I changed the configuration in ESPhome to connect to the wifi repeater instead of the wifi router. Since then I am no able to get the binary sensors working.

@dproffer:

I found already this topic but I was unable to configure my repeater. The repeater software used in this topic is for an ESP8266. I have an ESP32 so it is another software which is a bit different.

@Rudd-O:

If I understand well, I need to buy a wifi repeater with an ethernet connection. I connect via ethernet the repeater to my internet box and configure a new access point. Am I right? If yes, it will be better to have an ESP32 with an ethernet port. I will then direct connect the ethernet cable if I need to use one anyway

Besides using such a board to make simple DIY smart home (Wi-Fi based) devices for complex IoT solutions, you can turn the ESP8266 microcontroller into a Wi-Fi repeater to extend the reach of your wireless network.

A Wi-Fi extender, also known as a Wi-Fi booster or repeater, is a device used for amplifying the Wi-Fi signal and extending its coverage. They are used for eliminating dead zones in your home or office.

In large houses or outside, the connection of the Wi-Fi router usually does not reach all corners. Even normal W-LAN repeaters are not as cheap as one would expect. An ESP8266 access point or Wi-Fi repeater, however, is! This can either amplify the Wi-Fi signal or serve as an access point via a LAN cable. Instead of using expensive accessories, this self-made solution is ready for use in a very short time.

All other devices in the vicinity can now also connect via the ESP8266 Wi-Fi repeater or access point. Optional: Use LAN ConnectionIf you prefer a LAN connection, you can also use it. This requires an ENC28J60 adapter, which is connected to a NodeMCU via SPI, as described here:NodeMCU/Wemos ESP8266 ENC28J60 D6 GPIO12 MISO D7 GPIO13 MOSI D5 GPIO14 SCLK D8 GPIO15 CS D1 GPIO5 INTD2 GPIO4 RESET Q3/V33 3.3V GND GNDThe same adapter can also be used for a Raspberry Pi Zero. As we have seen, however, the data rate is not perfect, which is why I prefer the WiFi variant.

Note: If the repeater is far from your router, it will have low connection speeds, but we do not require fast speed for most IoT projects. I needed an inexpensive way to increase the Wi-Fi range so that my IoT devices could connect to the Internet on a remote Wi-Fi router and send notifications to my phone. This ESP8266 repeater can extend your signal up to 300 feet with a good connection.

I flashed this to my esp8266 and can not get it to work. It fails to keep the STA settings when it reboots. It comes back online with the default settings. When I fill in the AP settings is does store those as the web interface shoes and does change the wifi name as well. Any help you could suggect would be appreciated.

Wow! This really worked and was better and cheaper than a Pi Zero hotspot. I just had to play around with the distances from the ESP8266 repeater to the router and to where I want to access the internet.

How to Build WIFI Repeater/Extender with ESP8266 Node MCU

I have the ESP-M1 which is smaller and cheaper than other esp-based modules and I will explain step by step how to configure it to be a wifi repeater. These instruction were tested in an Ubuntu 16.04 system.

Internet speed

You can easily check the browsing speed delivered by the ESP32 WiFi repeater. Simply connect your computer or mobile to the WiFi network using the ESP32 repeater. Open your browser and conduct a speed test at speedtest.net.

Conclusion

ESP32 or ESP8266 can easily be converted into a WiFi repeater by configuring it as a NAT router. Depending upon the network, the repeater can deliver more than 15 Mbps speed. It can be used as a separate network for guests or for smart home automation appliances. The repeater can also extend WiFi to other rooms or floors of a home or office, particularly where the primary WiFi signal is weak. Any mobile adaptor can power the ESP32 WiFi extender through a Micro-USB cable.

Be it for home automation or Industrial IoT, smart campus or smart office, a WiFi repeater/extender is highly essential for covering large areas with a robust internet network. But WiFi repeaters are expensive and consume a lot of power. Setting it up is a lengthy process, which requires considerable effort.

So today, you will learn to build a WiFi repeater that costs only Rs 150 and also has security options along with mesh for long-range connectivity. Even if a single WiFi repeater fails, others in the mesh network will automatically take over and manage the network connections.

After this, open 192.168.4.1 and connect the ESP to that WiFi router for which you want the ESP to become a repeater. Upon entering the router SSID and password, you will get an option for making a mesh repeater or not. Select as per your choice. Then set the name of the WiFi repeater and if you wish, set the password as well.

i got goosebumps from linux. (from a thousand cross-compiling effort for an exotic openwrt package i had only a single success). the nodemcu boards anyhow seems working as i tested them with arduino ide uploading wifimesh example code,

my laptop has the virtualbox app badly broken beyond repair. i can try only kali linux on hand which is permanent root access and someone advised against. (stupid intel atom tv-boxes with hybrid 32bit efi and 64bit system, only kali was able to boot up/install)

i will dig after the open-sdk.

i have a bunch of wroom-esp32 as well. there i found some mesh project just not that compact solution as the martin-ger stuff. e24fc04721
