Wifi problem 20% pakketab

[scifo]

Hej Folkens.

Så er den gal med mig igen.

Efter geninstallationen af Ibex har jeg nogle sære problemer, systemet har godt nok fundet mit netkort, og jeg er forbundet til internettet, men oplever at jeg har stort pakketab, ex. kan det være meget besværligt at hente nye pakker ned da jeg periodisk mister forbindelsen.
Jeg kan dog ikke se på wifi ikonet at forbindelsen er væk, den viser normalt forbindelse.

Det viser sig ved i synaptic at den siger at den ikke kunne hente fejlen, i FF får jeg siden kan ikke vises.

Det skal lige siges at Ibex selv fandt kortet.

Ret frustrerende, nogle forslag?

Her er lige en lspci:

Hej,

Hvordan har du installeret din driver til wireless?

Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

Fra release notes

Atheros ath5k wireless driver not enabled by default

The version of the ath5k driver for Atheros wireless devices included in Linux 2.6.27 interferes with the use of the madwifi driver for some wireless devices and as a result has been disabled by default. Many Atheros chipsets will work correctly with the madwifi driver, but some newer chipsets may not, and the madwifi driver may not work with WPA authentication. If you have an Atheros device that does not work with madwifi, you will want to install the linux-backports-modules-intrepid-generic package, which includes an updated version of the ath5k driver. While not installed by default, this linux-backports-modules-intrepid-generic package is included on the Ubuntu 8.10 CD and DVD images for ease of installation.

Du har alt for lav hastighed

Bit Rate=1 Mb/s Tx-Power=27 dBm

Burde være 54 Mb/s

-> Skal jeg så prøve at installere linux-backports-modules-intrepid-generic?

-> Griner, har jeg fundet ud af men både mit kort og routeren kan køre N, så "burde" jeg ikke kunne køre 300?

Sorry... er vist lidt tungnem...

Har installeret pakken, og genstartet, uden held

samme iwconfig som sidst.

Hej,

Giver det ikke mulighed for at installere driveren under System -> Administration -> Hardware drivers?

[scifo]

Hej igen,

Nej, der er kun mine restricted nvidia drivere.

Hej

Jeg havde et problem der ligner dit, på min asus eee.
Jeg installerede windows driveren og så kørte det bare fint: https://help.ubuntu.com/community/EeePC/Fixes under overskriften:"Workaround: Ndiswrapper"

Efter jeg havde kørt denne (Med en driveren fra min cdrom til netkortet (win)) kører det, jeg kører dog kun 54 mb/s, er der ikke N understøttelse i ubuntu?

Skulle det ske at der kommer flere folk ind og læser dette, kan jeg oplyser at fejlen lå i min router, den er defekt og smider forbindelsen et par gange i timen i ca. 10 sekunder.

Løsningen var at kontakte producenten og få den byttet!
