Bonjour communauté,
Voici mon problème :
Installation de ubuntu 16.04 sur une nouvelle machine ( ACER ASPIRE V3-574TG-58LC )
lorsque je me connecte à un wifi quel qu’il soit, mon débit max est de 1mb/s.
mon signal est bon j'effectue les test près de ma box
voici ci-dessous les opération effectuées && les résultats du log wificheck
Merci
J'ai essayé quelques manips tel que :
sudo iwconfig wlp3s0 rate " auto et 54M"
; pas d'erreures visibles
sudo ifdown wlp3s0
réponse : périphérique inconnu ; j'avoue ne pas comprendre
sudo ifdown -a
sudo ifup -a
résltat : malheureusement toujours à 1mbps
wificheck :
