Connexion lente et instable
S'lut,
Depuis quelques temps maintenant, ma connexion internet (réseau Wifirst SmartCampus en résidence universitaire) subit sans cesse des baisses de régime. J'ai à de rares moments un bon débit mais le plus souvent la connexion se fait extrêmement lente.
Voilà pour les infos de base :

Re : Connexion lente et instable
Bonsoir,
Il sont toujours aussi rigole les gars des services tech .... un malware sous ubuntu .. ha ha ha ou un probleme matériel, re ha ha ha....
Il n'as pas grand chose a faire, tu eux essayer de remplacer ton module actuel (ath5k) par ndiswrapper et voir si le probleme continu ou pas.... mais dans ce type de reseau univesitaire en roaming, ce genre de probleme est frequent
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).
