[Résolu] connexion wifi très lente

bonjour,
je suis sur un why W253EU et j'ai un problème de connexion sur mon routeur (mobil wi-fi huawei E5786Bs) depuis 15 jours. cela fonctionnait très bien puis sans avoir fais de mise a jours quelconque la connexion a ralentie et reste maintenant très faible. Les paramêtres de connexion stipule pourtant une très bonne connexion. Auriez vous une solution s.v.p? Merci a tous!

Re: [Résolu] connexion wifi très lente

Bonjour,

Pour réunir toutes les informations utiles pour cerner le problème, il existe un "outil" effectuant tous les tests et consigne les résultats dans un fichier de log compréhensible par les spécialistes: wificheck.

Pour l'installer, il suffit de coller cette commande dans un terminal ([Ctrl]+[Alt]+[T]):

Code:

 wget -N -t 5 -T 10 https://framagit.org/cracolinux/wificheck/raw/master/wificheck && chmod +x wificheck && ./wificheck

Cette commande crée un fichier wificheck.log dans le dossier personnel. Il ne reste plus qu'à copier le contenu de ce fichier sur le forum.

Cordialement.
