Wifi qui se coupe régulièrement

Bonjour,

depuis que je suis passé à Ubuntu 18.04 TLS (clean install), le connexion avec le routeur wifi de mon appartement est intermittent : régulièrement (> 3 fois / jours) je ne recois / n'emet plus rien (syndromes typique : chat qui s'interrompt, mails qui partent pas, vidéo qui ne chargent plus etc.)

J'éteint le wifi de mon ordi et rallume, me reconnecte au routeur et ca repart.
Précision:
- cela n'arrive pas sur le wifi de mon université
- ma collocataire qui est sous mac n'a pas ce problème.

Voici le résultat du wificheck

Re : Wifi qui se coupe régulièrement

Bonjour,
J'ai également ce genre de problèmes. Au bout d'un certain temps ça revient mais c'est vrai que c'est pénible. Si quelqu'un a la solution, il fera des heureux!

Re : Wifi qui se coupe régulièrement

Bonjour,

@Maïeul

Vu :

Il faudrait passer sur un chiffrement WPA2, comme indiqué au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

Et pour :

iwconfig

Bit Rate=1 Mb/s 

Tu peux tenter la procédure de la Doc > wifi#connexion_lente ?wifi#connexion_lente ?

§ 6.6 a écrit :

Si vous voyez Bit Rate=1Mb/s alors tapez :

sudo ifdown wlp58s0
sudo iwconfig wlp58s0 rate 54M
sudo ifup wlp58s0

Enfin, faites "iwconfig" pour vérifier qu'il vous met bien Bit Rate=54Mb/s . Voilà qui devrait aller mieux !

pour que ça reste permanent : Ajoutez dans /etc/rc.local (avant la ligne exit 0)

/etc/rc.local

 ifconfig wlp58s0 up
 iwconfig wlp58s0 rate 54M
