No luck here. With wpa_supplicant and dhcpcd in runlevel boot the interface would not come up. I only get | Code: | $ su -c "/etc/init.d/dhcpcd start && /etc/init.d/wpa_supplicant start"

Some notes:
- I think you don't need to start wpa_supplicant manually, dhcpcd should take care of that
Try stopping both services, kill any leftover wpa_supplicant instances (should there be any) and restart just dhcpcd.
- /etc/conf.d/net is not used (or needed) by dhcpcd or wpa_supplicant |

| No chance. Removed wpa_supplicant from the runlevels, but still no interface. Even the wireless LED stays dark. Should I recompile opnerc with USE=-netifrc? |

I have USE=-netifrc set, but I don't know if you actually have to do that.
Does wpa_supplicant start at all? |

No, you just need to have /lib/dhcpcd/dhcpcd-hooks/10-wpa_supplicant which comes with the default installation.
What does say? |

Seems to be equivalent to what I already had in this file, except DIR | Code: | $ cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
# ctrl_interface=/var/run/wpa_supplicant
# ctrl_interface_group=wheel
update_config=1
network={ |
But this alone didn't make it work. I also had to uncomment the last line in /etc/conf.d/wpa_supplicant which was not needed for the old setup. | Code: | # conf.d file for wpa_supplicant
#
# Please check man 8 wpa_supplicant for more information about the options
# wpa_supplicant accepts.
#
wpa_supplicant_args="-Dnl80211" |
Finally putting wpa_supplicant again into default runlevel made it work. At least for wireless.

After the above mentioned changes, it seems top run well and I get | Code: | $ ps -A | grep wpa
2242 ? 00:00:00 wpa_supplicant |
My question now is, should wpa_supplicant automatically be started by dhcpcd or be in runlevel itself? |

Somehow it seems to not be triggered. How could I make sure it works? If possible I'd like to go without having wpa_supplicant in the runlevel. |

The last line shows that dhcpcd doesn't think this is a wireless interface.
Here's the code that dhcpcd uses to work it out on Linux : link
Maybe a driver bug?

I am too far from understanding the program code in link.
Could you guide me how to check about a possible driver bug? What informations do you need? |

Take a look at dmesg: is the wireless interface well initialized? does it need a missing firmware? is the rfkill switch OK?

which version of dhcpcd do you have ? wpa support is starting from version 6.

I had not, but after recompiling the kernel with CONFIG_CFG80211_WEXT=y it finally works.
May I propose this should be mentioned at the beginning of this guide because the old setup using net-misc/netifrc does not need wext compatibility. |
