Re: disable software blocking of wifi?

[znavko@disroot.org]

Thank you, Gábor Boskovits, for being awesome! I've tried this again and helped. Previously it was strange for me not to see wlp2s0. But I do it again and I have Internet automatically after boot.

I did exactly this: blacklisted ideapad_laptop, reconfigured, rebooted. And have Internet.

# gedit /etc/config.scm
...
(operating-system
...
 (kernel-arguments '("modprobe.blacklist=pcspkr,snd_pcsp,wmi,bluetooth,pata_acpi,ideapad_laptop"))
)

# guix system reconfigure
# reboot

After reboot I see

$ rfkill list all
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

$ ping gnu.org
PING gnu.org (209.51.188.148): 56 data bytes

Do I need to rewrite my config with phy0 interface instead of wlp2s0?

(wpa-supplicant-service-type config =>
                       (wpa-supplicant-configuration
                         (interface "wlp2s0")
                         (config-file "/etc/wpa_supplicant/wpa_supplicant.conf")))

Also do I need blacklist wmi and pata_acpi?

Why I have not ethernet interface now?
