Dotaz: instalace wifi

[Karel100]

Ahoj, jsem začátečník a mám problem zprovoznit wifi na ntb OS ubuntu 20.04?

V lspci by mělo být vidět co přesně je to za zařízení.

A jinak první krok je podívat se do dmesg, jestli jenom nechybí firmware. Bohužel poslední dobou tu bylo několik dotazů na realkeky, které vyžadovaly out-of-tree driver.

Jsem zagůglil Realtek Semiconductor Co., Ltd. Device c82f a hned v prvním výsledku někdo píše, že bylo potřeba stávajícímu driver vnutit to PCI ID změnou ve zdrojáku. Rozhodně bych ale nepostupoval tím způsobem co tam předvádí (stažení vanilkového trunku (!)), ale (pozor, tohle jsem zkopíroval z rok staré bash_history kdy jsem upravoval driver pro CH341, možná bude lepší zagooglit něco jako "ubuntu/debian compile changed module linux-source")

• Nainstaloval bych rozumně nový kernel (Ubuntu na to má asi HWE nebo se to jmenuje backports nebo bude PPA, kdo ví).
• Nainstaloval bych k němu balíček linux-source a vlezl do /usr/src/... (viz dpkg -L na ten balíček)
• pak tam mám

  make oldconfig
  make menuconfig
  make prepare
  make -j 4 modules_prepare
  make SUBDIRS=scripts/mod
  make -j 4 SUBDIRS=drivers/usb/serial/ch341 modules
  make -j 4 SUBDIRS=drivers/usb/serial modules
  ls -l drivers/usb/serial/ch341.ko
  insmod drivers/usb/serial/ch341.ko
  

  kdo ví v jakém pořadí se to má spouštět a co z toho bylo potřeba
• Ještě pro úplnost dodávám tuhle změnu (z git log -p na ten soubor v gitu kernelu), takže možná chceš trochu jiný driver:

btw: kdyz vkladas vystup, tak ho pred odeslanim oznac a tukni na tlacitk <pre> aby se zachovalo formatovani, to jak to bude vypadat po odeslani poznas kdyz musis tuknout na "Nahled komentare", porovnej sam rozdil v prehlednosti toho co si poslal neformatovane, a to same formatovane pres <pre>

Tak to je přesně to, co se píše v tom příspěvku na askubuntu.

[Karel100]

Jóo perfektní, funguje to. Ještě mi prosím pomozte rozchodit touchpad, děkuji moc

[k3dAR]

nevidim tu info co za touchpad, co za stroj, takze spis zaloz nove tema kde v nazvu rovnou uvedes jakej stroj :)
