| 29 | <p>I finally got around to installing Void GNU/Linux on my main | ||
| 30 | computer. Rolling release, non-systemd, need I say more?</p> | ||
| 31 | |||
| 32 | <p>As with all GNU/Linux distributions, wireless networks had | ||
| 33 | me in a fix. If you can see this post, it means I’ve managed | ||
| 34 | to get online. It turns out, <code>wpa_supplicant</code> was detecting the | ||
| 35 | wrong interface by default (does it ever select the right | ||
| 36 | one?). Let us fix that:</p> | ||
| 37 | |||
| 38 | <pre><code>$ sudo rm -r /var/service/wpa_supplicant | ||
| 39 | $ sudo killall dhcpcd | ||
| 40 | </code></pre> | ||
| 41 | |||
| 42 | <p>What is the right interface though?</p> | ||
| 43 | |||
| 44 | <pre><code>$ iw dev | ||
| 45 | ... | ||
| 46 | Interface wlp2s0 | ||
| 47 | ... | ||
| 48 | </code></pre> | ||
| 49 | |||
| 50 | <p>Aha! Let us run <code>wpa_supplicant</code> on that interface, as a | ||
| 51 | background process:</p> | ||
| 52 | |||
| 53 | <pre><code>$ sudo wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf | ||
| 54 | $ sudo dhcpcd -B wlp2s0 | ||
| 55 | $ ping google.com | ||
| 56 | PING ... | ||
| 57 | </code></pre> | ||
| 58 | |||
| 59 | <p>Yay! Make those changes perpetual by enabling the service:</p> | ||
| 60 | |||
| 61 | <pre><code>------------------------------------------------------ | ||
| 62 | # Add these to /etc/wpa_supplicant/wpa_supplicant.conf | ||
| 63 | OPTS="-B" | ||
| 64 | WPA_INTERFACE="wlp2s0" | ||
| 65 | ------------------------------------------------------ | ||
| 66 | $ sudo ln -s /etc/sv/wpa_supplicant /var/service/ | ||
| 67 | $ sudo ln -s /etc/sv/dhcpcd /var/service/ | ||
| 68 | $ sudo sv restart wpa_supplicant | ||
| 69 | $ sudo sv restart dhcpcd | ||
