Wow! It’s taken me over a week to find just the right combo of advice from a number of really helpful blogs to help me setup raspberryfai with mt TP-Link TL-WN721N USB WiFi adapter. I tried so many different steps that I couldn’t remember what I’d done. I thought that the wicd-curses utility would work like a charm but it hung my RasPi a few times.
Now that it’s setup, I shall call it raspberrywifai.
The blog which was most helpful was this post written almost 2 years ago. Just follow the steps especially on how to get the firmware for the TP-Link USB adapter. The only exception was that the following command didn’t work in my case,
pre-up wpa_supplicant -Dwext -i wlan0 -c /etc/wpa_supplicant.conf -B
Instead I just have to change it to the simpler form of (my wpa_supplicant.conf file is kept in its own folder):
In order to get the psk value, you can’t just type in your WPA2 passphrase, you need to run the following command:
sudo wpa_passphrase ssid passphrase
To be sure that it is indeed connected and seen as a USB device on my RasPi, I run lsusb, a command I learned from this post.
Now that raspberryfai has become raspberrywifai, I can bring it out for a spin this weekend.
