WPA Woes
</h1>
<div class="post-text">
<p>I finally got around to installing Void GNU/Linux on my main
computer. Rolling release, non-systemd, need I say more?</p>
<p>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, <code>wpa_supplicant</code> was detecting the wrong interface
by default (does it ever select the right one?). Let us fix that:</p>
<pre><code>$ sudo rm -r /var/service/wpa_supplicant
$ sudo killall dhcpcd</code></pre>
<p>What is the right interface though?</p>
<pre><code>$ iw dev
...
Interface wlp2s0
...</code></pre>
<p>Aha! Let us run <code>wpa_supplicant</code> on that interface, as a
background process:</p>
<pre><code>$ sudo wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf
$ sudo dhcpcd -B wlp2s0
$ ping google.com
PING ...</code></pre>
<p>Yay! Make those changes perpetual by enabling the service:</p>
<pre><code>------------------------------------------------------
# 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</code></pre>
