Salut salut !
J'ai un petit souci de connexion et je n'arrive pas à trouver l'origine ... je débute sur ubuntu 🙂
Je suis en dual boot avec windows 10 et je vois clairement une différence de connexion entre les 2 :
- Ubuntu : wifi 2 barres de réseau / 3 m de la box sans obstacle / coupure de temps en temps.
- Windows 10 : wifi au taquet / 2 étage entre l'ordi et la box / sans soucis.
En zonant sur le fofo j'ai bien compris que mon bit rate était a 1Mb/s et que c'est sans doute ça qui posait problème mais je ne peut pas changer la valeurs car mon wireless s'appelle wlp2s0 et quand je veux changer la valeur il me met que le périphérique est non reconnu ...
Je remercie d'avance la personne qui pourra m'aider
