Probleme de stabilité en WIFI. Intrepid sur un aspire 5610z
Bonjour
Depuis environ 2 semaines le wifi n est plus stable.
Il y a des sortes de déco. le wifi reste en connecté mais plus d accès a internet.
je trouve ca dans le journal mais je ne sais pas si cela a un rapport :
Feb 24 00:29:13 lilo-laptop kernel: [ 8555.476890] wifi0: rx FIFO overrun; resettingparfois, internet revient tout seul. Sinon je dois desactiver le WIFI puis le réactiver.
Enfin, le réseau est composé d une freebox branchée sur un WRT54Gs avec le DD WRT
Ca a l air de beaucoup plus se produire quand j utilise skype en vocal mais ce n est peut etre qu un effet
pour ce qui est demande dans le A LIRE, voila les resultats :
