Kan simpelthen ikke få trådløst netværk til at virke i 10.04

[tmntmn]

Hej Alle

Jeg har en ASUS UL30A hvor trådløst netværk virker i WINDOWS 7 og det virkede også rimeligt i før jeg opgraderede til 10.04.

Det er simpelthen ustabilt og mister forbindelsen jævnligt og kører meget langsomt. Hvis jeg starter en torrent, kører det kun ganske kort hvorefter al aktivitet går ned på 0, hvorefter netværksforbindelse falder af.

Jeg har læst div. tråde og forsøgt mig med compat-wireless, desværre uden det store held.

Dette er mit eneste problem med ubuntu, ellers er alt perfekt.

Jeg har pastet følgene fra terminal:

På forhånd tak.

Hej

Jeg flytter lige tråden til Netværk, så kan dem som er gode på det område hjælpe dig videre.

Du kunne prøve at sætte det op med openDNS

Det kan være det hjælper.

Jeg har på en enkelt af husets pc'er oplevet et lignende problem.
Det hang på en eller anden måde sammen med kombinationen af WPA-kryptering og skjult neværk.
Med skjult netværk og WEP kørte det uden problemer
Med WPA og skjult netværk meget problematisk
Med WPA og netværk som broadcaster ingen problemer.
Så hvis du er koblet til skjult netværk kan det være der problemet ligger.
Jeg fandt ikke ud af den præcise årsag, men formentlig er den hardwarerelateret, for den pc som havde problemet kører 10.04 - det samme gør en anden pc uden problemer, en anden kører 9.10 - en tredje kører win XP - en fjerde windows vista -og en femte Mac Leopard - også alle uden problemer.

Det korte af det lange er: hvis du kobler op til et netværk, som ikke broadcaster, så prøv at ændre det i routerens indstillinger og se om det ikke hjælper.
