Materials Needed ================

To build a DIY Wi-Fi range extender, you will need the following materials:

• A Raspberry Pi (or any other single-board computer)
• A Wi-Fi adapter (compatible with your router's frequency band)
• A power supply for the Raspberry Pi
• A USB cable
• A computer or mobile device for configuration
• A router (to connect to the extender and extend the Wi-Fi signal)

Step-by-Step Guide =====================

Step 1: Configure the Router

First, configure your router to work with the DIY Wi-Fi range extender. Log in to your router's web interface and set up the Wi-Fi network name (SSID) and password. Make sure to note down the SSID and password as you will need them later.

Step 2: Set Up the Raspberry Pi

Insert the SD card into the Raspberry Pi and boot it up. Install the Raspbian operating system and configure the Wi-Fi adapter to connect to your router's network. You can do this by editing the `/etc/wpa_supplicant/wpa_supplicant.conf` file and adding the following lines:

``` network={ ssid="Your Router's SSID" psk="Your Router's Password" key_mgmt=WPA-PSK } ```

Step 3: Install the Wi-Fi Extender Software

Install the `hostapd` and `dnsmasq` packages on the Raspberry Pi to enable it to act as a Wi-Fi access point.

``` sudo apt-get install hostapd dnsmasq ```

Step 4: Configure the Wi-Fi Extender

Edit the `/etc/hostapd/hostapd.conf` file to configure the Wi-Fi extender's settings. Add the following lines to the file:

``` interface=wlan0 driver=nl80211 ssid=Your Wi-Fi Extender's SSID hw_mode=g channel=6 wpa=2 wpa_passphrase=Your Wi-Fi Extender's Password wpa_key_mgmt=WPA-PSK ```

Step 5: Start the Wi-Fi Extender

Start the `hostapd` service to enable the Wi-Fi extender.

``` sudo service hostapd start ```

Step 6: Connect to the Wi-Fi Extender

Use a computer or mobile device to connect to the Wi-Fi extender's network using the configured SSID and password.
