[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.

Re: [SOLVED] Latest full system upgrade DHCPCD problem

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.

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

Roy Marples wrote:

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
