[SOLVED] Latest full system upgrade DHCPCD problem

I have done a full system ugrade this night and the latest dhcpcd package give me trouble.
I'm on a lenovo laptop and I was not able to connect to wireless interface.

ip link

Give me the error : NO CARRIER and was showing my 2 interface down

ip link set wlp7s0 up

was not working so downgrading to dhcpcd 6.9.4-1 solved my problem.

Indeed, I'm using wpa_supplicant to manage my wireless connection, so this is working for me too on dhcpcd 6-10.

Thanks, for the cue smile

-- mod note: this post was merged in from it's own thread.  Trilby --

Not really sure if this is the best place to go, but basically:

sudo dhcpcd wlp3s0

Used to work, but no longer.

sudo wpa_supplicant -Dnl80211 -iwlp3s0 -c/etc/wpa_supplicant.conf
sudo dhcpcd wlp3s0

Used to work, and still works. Why doesn't the previous one work anymore? I'm not sure what I did, maybe it was an updated to one of these two? But it started happening after a reboot 1 or 2 days ago. No there is nothing in /etc/wpa_supplicant/.

I'm on a MacBook Air 6,2, using broadcom-wl 248 dkms module from AUR, latest version of all software according to pacman.

And https://bbs.archlinux.org/viewtopic.php … 6#p1594446.  Also see the warning in the wiki https://wiki.archlinux.org/index.php/Dh … supplicant

EDIT: I've just merged two nearly identical threads.

I *highly* recommend to work with upstream on this issue. Open a ticket or send a message to their maillist and request clarification why the files were moved. This is better way to solve the issue than just copy files into the old location.

Re: [SOLVED] Latest full system upgrade DHCPCD problem

Anatolik, the link from the flag in the wiki provides upstreams reasons:

Grudgingly accede to the vocal minority that dhcpcd should not attempt to start wpa_supplicant by default on a wireless interface, even if a wpa_ctrl interface is configured for it and wpa_supplicant is not yet started.

http://roy.marples.name/projects/dhcpcd … ecd9a8b839

The dhcpcd documentation has been appropriately updated and it covers how to add the example hooks properly by copying/linking to them.  This was an intentional upstream change.  Of course if we're even more annoying than that vocal minority, perhaps we can get him to change it back wink
