Latitude E6400 (carte Intel Corporation Wireless WiFi Link 5100)
Bonjour,
Je suis l'heureux possesseur d'un DELL LATITUDE E6400 sur lequel je viens d'installer une Ubuntu 8.10. Tout s'est très bien passé avec le wifi reconnu du premier coup (carte Intel Corporation Wireless WiFi Link 5100)
Mais je m'aperçois que mon débit habituellement aux alentours de 500 ko/s a chuté vers 80 ko/s. J'ai vérifié les débits des autres ordinateurs ..... tous sont vers 500 ko/s ...... même celui de mon E6400 sous Win*
Le module utilisé est un iwlagn et j'ai tenté ndiswrapper sans succès 
Voici toutes les caractéristiques :

Re : Latitude E6400 (carte Intel Corporation Wireless WiFi Link 5100)
Pour moi, j'ai résolu le problème : ma box était bridée à 11 MB/s ..... en auto ou 54 MB/s ça marche beaucoup mieux 
Je ne mets pas "résolu" car il semble que d'autres personnes aient des soucis
