Kortet fungerer sådan set ok ud af æsken, men jeg har oplevet nogle gange at blive hældt af netværket ud af det blå. Jeg synes ikke jeg laver noget bestemt når det sker. Det sker ikke særlig ofte. Jeg ved ikke endnu om det er med en bestemt frekvens men så er det i hvert fald over 10 minutter. Det er i øvrigt en Lenovo t60 som jeg købte brugt for en uges tid siden.
Her er lidt sys-info:

(Min wlan0 ser ikke altid sådan ud. Det er bare fordi jeg ikke lige kan komme på nu).
Sidst det skete skyndte jeg mig ind for at lure i kernel-loggen og ganske rigtigt - den var proppet med fejl. I det øjeblik den hoppede af forbindelsen så den således ud:

Osv, osv...
Herefter er der en anden fejl tilstede konstant som genskabes præcist hver andet minut:

(Det er et udsnit)
Jeg har ikke testet om det også sker jævnligt (nok) i windows. Men jeg dual-booter med windows så jeg skal nok kikke senere. Jeg er i hvert fald blevet smidt af wifi på windows også men jeg har ikke brugt det så meget at jeg tør konkludere at det skulle være konstant nok til at ligne situationen på ubuntu.
Giv mig endelig inspiration til fejlfinding. Jeg er ikke den store netværkshaj.
