Trådløst netværk virker pludselig ikke

[swoop]

Godaften folkens

Pludselig kan jeg ikke længere tilgå mit trådløse netværk fra min Ubuntu 8.10. I går aftes var der intet problem og har intet ændret hverken på maskinen eller i netværksopsætningen.

Hvis jeg kobler direkte kabel til etableres forbindelsen straks og kan i øvrigt fra andre maskiner godt koble trådløst op. Router er forsøgt genstartet.

Ved ikke lige hvilke oplysninger, der er nødvendig i fejlsøgning, men /var/log/daemon.log viser:

Hvad kan være galt? På forhånd tak for hjælpen.

Edit: Pokkers ser først nu indlægget skulle lægges under hardware.

For overskueligheds skyld, flyttes denne lige til Netværk.

Googlede lige på den sidste linie i din log-fil og fik denne liste af muligheder:

Umiddelbart virker det til at være en bug i network manager.

Kan der måske være tale om et trådløst problem af anden karakter?
Jeg oplevede her til aften at min trådløse forbindelse pludselig døde bedst som jeg surfede. Genstart af router uden effekt. Og diverse kommandoer som burde virke havde heller ingen effekt.
Det viste sig at problemet sad på den bærbares forside: der er en lille skyder som kan aktivere/deaktivere den trådløse forbindelse, og den er åbenbart lige så stille blevet skubbet over så kortet var deaktiveret ad mekanisk vej. Men det var først da mit blik faldt på de små blå lamper på pc at jeg kunne se at det var det der var galt.
Jeg siger ikke at det er dit problem, men den der knap skal man altså også lige huske på, når den trådløse falder ud.
