LUBUNTU :débit wifi très faible avec box à proximité
Bonsoir la communauté,
J'avais posé il y a longtemps un topic qui ressemblait très fortement à mon problème sauf que j'avais installé ubuntu et non lubuntu(mon os actuel).
Je pensais que faire:
gksudo gedit /etc/modprobe.d/blacklist.conf
blacklist bcma
blacklist brcmsmac
marcherait car ça avait résolu mon problème à l'époque, mais avec Lubuntu ça me désactive carrément le wifi.
Quelqu'un aurait une solution car j'aimerai bien resté sur cette os qui est extrêmement léger et rapide
Voici mes informations réseaux :

Re : LUBUNTU :débit wifi très faible avec box à proximité
Bonjour taimpus,
essaies :
sudo iwconfig wlan0 rate 54M
puis postes le résultat de
sudo iwlist scan
ensuite redémarres le PC
et re-postes le résultat de
sudo iwlist scan
Le débit est-il meilleur ?
