+I finally got around to installing Void GNU/Linux on my main
+computer. Rolling release, non-systemd, need I say more?
+
+As with all GNU/Linux distributions, wireless networks had
+me in a fix. If you can see this post, it means I've managed
+to get online. It turns out, `wpa_supplicant` was detecting the
+wrong interface by default (does it ever select the right
+one?). Let us fix that:
+
+```
+$ sudo rm -r /var/service/wpa_supplicant
+$ sudo killall dhcpcd
+```
+
+What is the right interface though?
+
+```
+$ iw dev
+   ...
+   Interface wlp2s0
+   ...
+```
+
+Aha! Let us run `wpa_supplicant` on that interface, as a
+background process:
+
+```
+$ sudo wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf
+$ sudo dhcpcd -B wlp2s0
+$ ping google.com
+PING ...
+```
+
+Yay! Make those changes perpetual by enabling the service:
+
+```
+------------------------------------------------------
+# Add these to /etc/wpa_supplicant/wpa_supplicant.conf
+OPTS="-B"
+WPA_INTERFACE="wlp2s0"
+------------------------------------------------------
+$ sudo ln -s /etc/sv/wpa_supplicant /var/service/
+$ sudo ln -s /etc/sv/dhcpcd /var/service/
+$ sudo sv restart wpa_supplicant
+$ sudo sv restart dhcpcd
+```
