How to Use Tenda USB Wi-Fi Adapter

If you're looking for a cost-effective way to add wireless connectivity to your Raspberry Pi, consider using a cheap mini USB Wi-Fi adapter. In this article, we'll go over the process of setting up and configuring a Tenda USB Wi-Fi adapter on your Raspberry Pi.

The first step is to set up static IP reservations on your network router, so each Pi gets a permanent IP address. This ensures that you can easily identify which device corresponds to which IP address. Additionally, you may need to scan for a list of the WiFi networks your Pi can see by running `sudo iwlist wlan0 scan`.

After setting up the static IP reservation, reboot your Pi entirely using `$ sudo reboot` to make sure the configuration sticks and your Pi joins the network automatically. Then, run `ifconfig` to find your IP address in the `wlan0` section.

If your Pi doesn't connect automatically within 10-20 seconds, you can manually refresh the interface to connect and get an IP address using `$ sudo ifdown wlan0 & sudo ifup wlan0`.

Next, edit your `wpa_supplicant.conf` file (`/etc/wpa_supplicant/wpa_supplicant.conf`) and add your wireless network settings to the end of the file.

Make sure that your `/etc/network/interfaces` file has a `wlan0` configuration. If not, you can create one by adding a new section with the following details:

```

auto wlan0

iface wlan0 inet dhcp

wpa_supplicant /etc/wpa_supplicant/wpa_supplicant.conf

```

Before configuring your USB Wi-Fi adapter, ensure that the Raspberry Pi sees it on the USB bus by running `$ lsusb`. This will list all connected devices, including your USB Wi-Fi adapter.

Some popular and affordable options for USB Wi-Fi adapters include:

* Kootek 802.11b/g/n USB WiFi adapter with Realtek RTL8188CUS chipset (usually available for under $10 from Amazon)

* Tenda W311Mi 802.11b/g/n USB WiFi adapter (usually available for under $10 from Micro Center)

* Edimax EW-7811Un 802.11b/g/n USB WiFi adapter (usually available for under $10 from Amazon)

These adapters are all relatively inexpensive and offer decent connection speeds and reliability.

In conclusion, setting up a cheap mini USB Wi-Fi adapter on your Raspberry Pi is a straightforward process that requires minimal technical expertise. By following these steps, you can add wireless connectivity to your Raspberry Pi at an affordable price.
