USB Wifi Adapter for the Raspberry Pi

No problems, worked first time and had not problems with insufficient power on USB port like some others. Very happy.

Brilliant

Small and effective. Works well in the house. Delivered within a couple of days. So all good.

I have a optical fiber internet internet + phone + TV connection. This USB Wifi Adapter for the Raspberry Pi doesn't work with 2019-07-10-raspbian-buster-full, whatever trick you may try, but it does perfectly with 2019-09-26-raspbian-buster-full, out of the box, no need of the driver CD included. (You can get these OS on https://www.raspberrypi.org/downloads/raspbian/). At the first boot with 2019-09-26-raspbian-buster-full, the raspberry dislays the nearby SSIDs and you've just to choose the right SSID and input the password of your internet connection device. If you look into the /etc folder, you can see that the wpa_supplicant.conf file has been entirely rewritten this way :

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=FR

network={
ssid="name-of-your-ssid"
psk="the-very-long-at-least-in-my-country-password-of-your-ssid"
key_mgmt=WPA-PSK
}

(The country=FR line must be twisted as to match your own country following the two-letter code https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements, for instance you should write country=DE if you live in Germany.)

I haven't noticed any other change in /etc.

So perhaps if you can't connect, you may alternatively try sudo nano /etc/wpa_supplicant/wpa_supplicant.conf, replace the whole text inside with ctrl_interface=DIR and so on down to }, type ctrl-X, y (for yes), return, and reboot the raspberry.

1. Plugged in ethernet.
2. ssh-ed into the pi.
3. Plugged in the WiFi adapter
4. Ran sudo raspi-config to configure the PI to use the WiFi adapter.
5. sudo reboot for good measure
6. Unplugged ethernet.
7. Confirmed, can ssh into PI over WiFi.
