ar barzh paour

non résolu en 16.04
1/12/2018 installation 18.04 qui en final résout le problème ..... (post #23 et suivant)
bonjour à tous
si ça parle à quelqu'un

voilà ce que je n'arrive pas à résoudre
je viens d'installer 16.04 sur une machine
la liaison WIFI tient 5 mn et se coupe
sur la même machine j'ai 14.04 et pas de soucis
(pour palier à ça j'ai tiré en provisoire un cable , maintenant je suis connecté en filaire)
je poste les deux résultats de wificheck

NB :

2-je n'ai pas accès à la gestion de la box , modifier les paramètres me parait délicat (pas impossible ...mais)

Bit Rate=1 Mb/s et pour ton interface Wifi : wlp2s7.

Voir la Doc > wifi#connexion_lente :

§ 6.5 a écritSi vous voyez Bit Rate=1Mb/s alors tapez :

sudo ifdown wlp2s7
sudo iwconfig wlp2s7 rate 54M
sudo ifup wlp2s7

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 wlp2s7 up

Recherche documentaire du 25/05/2017 > wifi-too-much-invalid-misc-how-to-fix-it

Wifi "Invalid misc", comment le réparer?
Voici quelques résultats:
root@debian:/home/love# iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:"SITI_Broadband-06E6-G"  
      ...
          Tx excessive retries:0  Invalid misc:202   Missed beacon:0
J'ai remarqué que la valeur augmente avec le temps et que mon wifi reste connecté, mais Internet arrête de fonctionner.

Cela ressemble à un problème typique d'interférence wifi. Essayez de localiser l'appareil causant le problème et, lorsque vous le faites, supprimez cette question car elle serait hors sujet. Il suffit simplement de désactiver la plupart des équipements électroniques et de faire attention à ce qui change lorsque les problèmes commencent, peut généralement résoudre 90% de ceux-ci.

Recherche documentaire du 09/03/2018 - Dans > linux.die.net/man/8/iwconfig

Tx excessive retries
Number of packets that the hardware failed to deliver. Most MAC protocols will retry the packet a number of times before giving up.
Nombre de paquets que le matériel n' a pas pu livrer. La plupart des protocoles MAC vont réessayer le paquet plusieurs fois avant d'abandonner.

Invalid misc
Other packets lost in relation with specific wireless operations.
Autres paquets perdus en relation avec des opérations sans fil spécifiques.

enfin merci de toutes ces infos
sur la première installation en 4.4.0-116 j'ai toujours des déconnexions wifi (je suis dessus pour ce post , j'ai été obligé de réactiver la liason deux fois)

ce qui n'est pas facile à comprendre c'est
pourquoi ça fonctionne sur une version et pas sur l'autre
pourquoi ça fonctionne sur une machine et pas sur l'autre ( là je peux comprendre à cause de la différence de matériel)
