Dotaz: Wifi problem lenovo

[masak]

Zdravím,
Moje lenovo ma HW přepínač k zapínání wifi. Pokud systém (linux mint - lmde) nabootuju s vypnutým hw přepínačem a zapnu ho už v nabootovaném systému, nedaří se mi rozfungovat wifi.

zkousel jsem:

modprobe -r iwlwifi
modprobe r iwlwifi

dmesg zahlasi:

Vyzerá to tak, že pri vypnutom wifi to system detekuje inak a preto už nemôžeš wifi znovu aktivovať.

Možno v linuxe nie je rutina, ktorá vie dynamický detekovať danú wifi z vypnutého stavu.

rfkill lunblock all je len softvérové odblokovanie.

Ako sa zmení dmesg,keď nabootuje systém s zapnutým wifi ?

[masak]

Díky za reakci, přikládám dmesg po startu.

"Možno v linuxe nie je rutina, ktorá vie dynamický detekovať danú wifi z vypnutého stavu..."

ale je, viz muj vypis dmesg. Po detekci zapnuti nahraje firmware a jede (rozdil ve vypisech pred a po zapnuti je jen v posledni radce)... Mam Lenovo R60 s Debianem.

Nicmene, k autorovi: mas nejaky prakticky duvod HW vypinat wifi? Ja mam svuj notebook asi 6 let a jeste jsem to nepotreboval. Naopak, kdyz jsem si s tim hral a zapomel ho ve vypnutem stavu, nekdy jsem pak (vetsinou kdyz se to nejmin hodilo) dlouze zkoumal proc mi nejde wifi a hledal vselijaka nastaveni..:))

[masak]

No mě se právě ten vypínač sám vypnul (asi jsem moc házel batohem). A on je docela fail, když máš pak někde vytáhnout notebook a ona ta wifi jako naschvál nejede...

[Petr]

Vterinove lepidlo nebo lepici paska Tvuj problem jiste spolehlive poresi...:)

[masak]

dobrý nápad, ale stejně bych rád věděl v čem je zakopaný pes...
