[SOLVED] No wifi working after switching to systemd

Hello there! Not sure if this is the place to post this question, but here it goes.

I've recently switched from openrc to systemd (204). Aside from being amazed for its speed, I've managed to get all working except wifi card. It doesn't even turn on.

I'm running Gentoo under a HP Pavilion DV2000 with a Broadcom BCM4311 wifi card. If I switch back to openrc, it works fine. But with systemd even iwconfig / ifconfig recognizes it (as if my kernel had not support for it).

I'm pretty noob to systemd, I would be glad if someone could throw me a clue about this. Thanks!

i have a similar setup, similar wifi card... on my laptop that is. i had systemd and ran into your problem. i resolved your problem by using gdm rather than startx. im sure lightdm would do the trick also.

https://wiki.gentoo.org/wiki/LightDM

give it a try.... if it fixes it, shout back and ill append systemd wikis suggesting lightdm. i also ran into not being able to use menus to load programs, and it resolved that also.

edit to note that i was talking about networkmanager.

With a little help of the journal I found this:

@acidDrum, I don't travel around, but only connect to two alternating wifis at home, which I got working with only dhcpcd and wpa_supplicant. That's another story NetworkManager ....

Hello,
with Fedora who use Systemd by default, NetworkManager was connecting me correctly to the Internet when I was using Gdm has display manager. Systemd use /dev/tty1 has the virtual terminal for display managers.

Than, I stop and disable the Gdm service with systemctl. I startx from /dev/tty6 after openning a session in that terminal. I had the experience of not being able to connect to Internet with NetworkManager because of insufficient privileges.

I logout and startx from /dev/tty1. I was able to connect to internet with NetworkManager. I read somewhere that Xorg must use the first virtual terminal /dev/tty1 with Systemd.

The Broadcom wireless cards are not too easy to support in Linux. Even if Systemd do not want to make your card work, you should be able to see it with lspci or lsusb depending on the port on which it is connected.

You can also load manually the appropriate Broadcom module and check with dmesg if the kernel complain about something, like firmware. If everething is ok, you should see your card with ifconfig -a and ip link show. Than wpa_supplicant and a dhcp client should be able to connect you to the Internet.

I always assure myself I can connect to Internet manually if something goes wrong with the network scripts. Than I can find more easily how to make the network support fo the distribution work.

You have several ways to connect automatically. The wpa_supplicant plus dhcpcd scripts, net.lo link to your network card and configure in /etc/conf.d/net, NetworkManager, Wicd, etc.

Removing dhcpcd and uninstalling net-misc/dhcp from systemd sysvinit solved problems for me, but do not know if it is the same problem as yours.

Mine was just that it was "reseting IP" all the time when using DHCP on wifi or wired.

Thank you so much to all of you, gentlemen, for your kindly help. Turns out that, as @Logicien said, I hadn't had enabled the b43 kernel module. So I did, and wifi worked.

I trusted on @ulenrich about his command to activate wpa_supplicant at boot, but it didn't worked and my wifi spot was refusing to connect. I figured out after many hours googling that I had to do
