Skončila podpora WinXP, které byly na počítači, který jsem si tehdy koupil. Po prozkoumání možností jsem se rozhodl vyměnit je za LinuxMint, hodnocený jako uživatelsky nejpřívětivější volně dostupný OS. S Linuxem nemám zkušenost a počítačově jsem negramotný. Zato mám ženu, počítačově stejně zdatnou jako já, která...

Posledního května jsem stáhl a vedle stávajících WinXP nainstaloval LM 17 Cinnamon 32-bit. Vše v pořádku, až na:
Kód: Vybrat vše
mint@mint ~ $ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
Když nebootuju do WinXP, vše běží, jak má. Když následně restartuju s bootem do LM, opět wifi běží. Když ale počítač úplně vypnu a nabootuju přímo do LM, wifi zůstane vypnutá s výše uvedeným výpisem rfkill a nelze zapnout.
Zkoušel jsem fyzicky wifi zapnout/vypnout tlačítkem i Fn + F10 – ani jedno nelze. Nastavení wifi v BIOS je defaultně enabled.
Pročítal jsem fóra mimo jiné na linuxmint.com, askubuntu.com, ubuntuforums.org i to Vaše...
