Paramétrage WIfi
Bonjour,
J’ai une Freebox V6 - Bande Wifi 2.4 Ghz – Normes 802.11b,g,n et un PC Asus – Wifi 802.11n – DualBoot Xubuntu 18.04 - Windows Vista.
J’habite un appartement assez récent (10 ans). J’ai de gros problème pour capter le Wifi sous Xubuntu quand le PC est dans une pièces éloignée de la Freebox (environ 17m). Ca semble mieux fonctionner sous Vista. J’ai essayé avec un répétiteur mais ce n’est pas vraiment mieux.
Pour différentes raisons je ne souhaite pas déplacer la Freebox.
J’ai exécuté le script wificheck préconisé par cracolinux en me plaçant à côté de la Freebox, car je n’arrive pas à l’éxécuter dans la pièce éloignée. Message « Résolution de framagit.org (framagit.org)… échec : Connexion terminée par expiration du délai d'attente. ».
Par contre lors de l'éxécution normale du script j'ai le messag suivant : ligne 74: nm-tool : commande introuvable
Pouvez vous m’indiquer s’il y a des paramètres à modifier, sur la Freebox ou sur le PC, pour améliorer la liaison Wifi.
Résultat de l'éxécution du script - SSID de ma box : MGFreebox

Re : Paramétrage WIfi
Bonjour,
Tu as testé un canal 6 ou un canal 11 ?
> quel-canal-wi-fi-choisir-pour-optimiser-son-debit
_ _ _
Conseils habituels :
> les-dix-ennemis-des-reseaux-wi-fi-
> Wi-Fi-connexion-amelioration,
_ _ _
Pour les réglages de bitrate et txpower :
Doc : wifi_optimisation#regler_les_parametres_reseaux
Dans le manuel : man pages
rate/bit[rate]
Pour les cartes supportant plusieurs débits, positionne le débit
en b/s. Le débit est la vitesse à laquelle les bits sont
transmis sur le médium, la vitesse du lien pour l'utilisateur
est inférieure à cause du partage du médium et des diverses
entêtes.
Vous pouvez ajouter le suffixe k, M ou G à la valeur
(multiplicateur décimal : 10^3, 10^6 et 10^9 b/s), ou ajouter
suffisamment de '0'. Les valeurs en-dessous de 1 000 sont
spécifiques à la carte, habituellement un index de la liste des
débit supportés. Utilisez auto pour sélectionner le mode débit
automatique (repli à un débit moindre pour les canaux bruités),
ce qui est le mode par défaut pour la plupart des cartes, et
fixed pour revenir à des paramètres fixes. Si vous spécifiez une
valeur de débit et ajoutez auto, le driver utilisera tous les
débits inférieurs et égaux à cette valeur.
Exemples :
iwconfig eth0 rate 11M iwconfig eth0 rate auto iwconfig eth0 rate 5.5M autotxpower
Pour les cartes supportant plusieurs puissances de transmission,
règle la puissance de transmission en dBm. Si W est la puissance
en Watt, la puissance en dBm est P = 30 + 10.log(W). Si la
valeur est post-fixée par mW, elle sera automatiquement
convertie en dBm.
De plus, on et off active et désactive la radio, et auto et
fixed active et désactive le contrôle de puissance (si ces
fonctions sont disponibles).
Exemples :
iwconfig eth0 txpower 15 iwconfig eth0 txpower 30mW iwconfig eth0 txpower auto iwconfig eth0 txpower off

[Résolu] Xubuntu 16.04 + Atheros AR9285 : wifi KO au (re)boot et cette réponse :
jdt37b a écrit :
xubu1957,
Pour info, dans un environnement encombré (bluetooth, téléphone DECT, murs, parties métalliques, autres réseaux wifi, ...) et à 6m de distance d'une box à 8000 kbps maxi, après moult tests et plusieurs semaines d'utilisation :
Ce qui a fait nettement la différence pour obtenir une connexion correcte en temps et en débit, c'est de baisser le tx-power et le bitrate de la carte Wifi comme ça :
Dans le fichier /etc/rc.local :ifconfig wls1 up iwconfig wls1 txpower 5mW iwconfig wls1 rate 11.0M autoSi ça peut être utile !
