 |
|
Hello all, this is my first post here (actually my first post anywhere with a Gentoo box  )
I've been enjoying Gentoo for a few days now and after some tinkering I have wifi working on my laptop using wpa_supplicant and dhcpcd. After getting wifi working with wpa_supplicant, I did the following:
1) emerge wicd
2) remove all net.* initscripts from all runlevels
3) add rc_hotplug="!net.enp2s8 !net.wlan0" to rc.conf
4) add /etc/init.d/wicd to default runlevel
But when I boot wicd won't work and I have to connect with dhcpcd manually. I can scan using iw, but I can't scan using iwlist or find any networks in wicd. Also, none of the "${wireless_*}" variables work in my conky. I'm glad I can connect but I'm confused as to why things are working this way. Any clarification on this is greatly appreciated. Let me know what additional output you want to see.

Only thing that comes to my mind is that the binary "blob" for the wifi device is outdated / does not work well with your kernel.
Have you checked if any other linux distro has the same issue with your wifi card? (known issues)
when money is not an issue swap out the wifi card when its unfixable.
some cards can utilize the windows binary blob ... also worth a try.
use another version of the wifi tools and see if its there.
boot from a livecd and see if the problem is there too.
influence of systemd / openrc / eudev / ... anything else?
just my ideas / thoughts, |

Thank you both for your replies, after reconfiguring my kernel a couple times I managed to fix the problem. I built "cfg80211" and "mac80211" as modules instead of building them straight into the kernel and now things seem to be working  .
@charles17: I only installed wireless-tools out of frustration and curiosity, I've actually had a lot of trouble with this wlan card with every distro i've tried.
Anyway, I'm confused as to why it works when those two things are built as modules, but not when their built-in? For now though I can mark this as solved, thanks again for the input! |
