Wifi Realtek RTL 8101 alimentation?

lo1405 · Le 05/12/2009, à 09:21

Bonjour,
J'ai un problème depuis que j'ai réussis à installer le driver pour le wifi. (environ septembre)
Si je suis sur batterie, je démarre, network manager ne cherche pas de wifi.
J'éteins et je rallume assez rapidement (pas après quelques heures), j'ai le wifi, network manager se connecte automatiquement.
Si je suis sur secteur ça marche pas à tous les coups.
Maintenant, j'enlève ma batterie et je mets le portable sur secteur. Quand je le fais déjà allumé, la "voyant" batterie (haut à droite) m'indique qu'elle charge ou qu'elle est à 0, bref il ne comprend pas vraiment que je l'ai enlevée mais ça marche. J'ai le wifi si je l'avais avant d'enlever la batterie, je ne l'ai pas si je ne l'avais pas.
Maintenant si je démarre avec la batterie déjà enlevée et donc le secteur branché, en haut à droite, le symbole est transformé en grosse prise blanche et j'ai d'office le wifi.
J'ai donc l'impression qu'il y a un lien entre alimentation et "lancement" du wifi.
Je précise pour certains que mon bouton wifi on/off est toujours allumé.
Mon portable: Toshiba Satellite U500 11E.
Ma version: 9.04 (tant que ça fonctionne 1/2 je préfère pas tenter le diable)
Mon carte wifi: realtek 9172.
Merci d'avance à celui qui trouvera la solution de mon problème.

bonjour,

lorsque tu est sur baterie, ton portable doit certainement passer en mode "économie d'energie" et donc il désactive ton wifi malgré le fait que le bouton du wifi soit sur "on"
Essaye donc quand tu allume ton portable sur batterie, de manipuler le bouton un coup sur "off" puis à nouveau sur "on" pour voir si cela ne regle pas le probleme.

Autre piste, voir dans le bios si tu n'as pas une option pour activer systematiquement les wifi au démarrage ou si il n'y a pas une option pour désactiver ce mode "économie d'energie" (oui, je sais pas top pour un portable, mais bon le temps de tester et tu sera fixé..)

Le problème c'est que je n'y connais pas grand chose.
Toucher un bouton wifi on/off, j'ai déjà essayé.
Pour le reste, il faudrait me donner plus d'explications.
