<p style="margin: 0px 0px 1.2em !important;">Si la perte du réseau
est liée à une montée de version, il y a des chances que cela
soit un problème de pilote de la carte wifi lié à la version du
kernel ou de l’absence du firmware propriétaire Intel.</p>
<p style="margin: 0px 0px 1.2em !important;">Puisque cela
fonctionne sous Mint, le plus simple est de comparer les 2 OS
(Ubuntu et Mint). </p>
<p style="margin: 0px 0px 1.2em !important;">Dans un premier
temps, il suffit de comparer le retour de la commande :</p>
<pre style="font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">
lspci -v | grep -A7 Network
</code></pre>
<p style="margin: 0px 0px 1.2em !important;">Les lignes “<em>Kernel
driver in use</em>“ et “<em>Kernel modules:</em>“ devraient te
renseigner sur le pilote et s’il est chargé dans les 2 cas.</p>
<p style="margin: 0px 0px 1.2em !important;">Il semble que le wifi
de l’<strong>Elitebook 8460p</strong> soit un “<em>Intel(R)
Centrino(R) Advanced-N 6205</em>“ et cela devrait être le
module noyau iwlwifi.</p>
<p style="margin: 0px 0px 1.2em !important;">Si le module est
correctement chargé dans les 2 cas, il se peut que tu n’aies pas
la bonne version du firmware. Pour vérifier, tu peux comparer le
retour de la commande :</p>
<pre style="font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">
sudo journalctl -b | grep iwlwifi
</code></pre>
<p style="margin: 0px 0px 1.2em !important;">Note : A la demande
du prompt, tu doit taper ton mot de passe en “<em>aveugle</em>“.</p>
<p style="margin: 0px 0px 1.2em !important;">Tu devrais y trouver
la ligne définissant le firmware trouvé, puis celle de son
chargement (loaded), enfin le nom de l’interface réseau qui a
été choisi.</p>
<p style="margin: 0px 0px 1.2em !important;">Par exemple, dans mon
cas :</p>
<pre style="font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">
journalctl -b | grep iwlwifi

</code></pre>
<p style="margin: 0px 0px 1.2em !important;">Si tu ne vois pas
apparaître ces lignes, il faut vérifier que le paquet
firmware-iwlwifi est bien installé et sa version, avec la
commande :</p>
<pre style="font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; font-weight: 550; background-color: rgba(119, 119, 119, 0.3); border-radius: 3px; display: inline;white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">
