Cannot set wireless up

I'm trying to install arch using the wireless connection on a laptop, but I can't set the wireless up.
The kernel module is ath9k which is activated and the connection wlp2s0 is still state DOWN after running the ip link set wlp2s0 up command.
The odd thing is that it shows me as connected to the wireless network (no security), but when running dhcpcd I get timed out.

Re: Cannot set wireless up

Check dmesg for relevant messages - specifically, any message posted during/after the 'ip link ...' command.

Also, post whatever output is showing you as connected.

Re: Cannot set wireless up

Sorry for the late response.
The only thing related to wireless is renaming the interface to wlp2s0 and ipv6 addrconf netdev up wlp2s0 link is not ready.
It seems that it doesn't give any error but it won't respond to any command either.

Re: Cannot set wireless up

I'll try to be more direct here, since you ignored my previous request.

it shows me as connected to the wireless network

What is 'it'?

Re: Cannot set wireless up

the connection wlp2s0 is still state DOWN after running the ip link set wlp2s0 up command.

Actual output is useful.  I suspect there is an "UP" inside the angled brakets in the output from `ip link` but the DOWN is for the state, right?

Setting the interface up is not sufficient, you need to connect to a network.  What have you done to connect to a network?  If you don't know what you should do, be sure to see the wireless page on the wiki.

Re: Cannot set wireless up

I'm having a similar problem, except I can't connect to my wireless network.  I installed the ipw2100 firmware for my chipset...dmesg showed "ipw2100: fatal interrupt.  Scheduling firmware restart", but after rebooting it doesn't show that message anymore.

When I try to use wifi-menu to connect to my network, it gives me a "failed to connect" error when I try to connect...But with netctl-auto enabled, it just tells me that my interface is controlled by netctl-auto and does nothing.  When I try to scan with "iw dev wlp2s2 scan | grep SSID", is shows "Operation not suppored (-95)", which apparently has something to do with the firmware not being loaded properly.

ip addr shows <NO-CARRIER,BROADCASE,MULTICAST,UP>, but the state remains DOWN.

I'm on a Thinkpad T41...The wireless indicator blinks...Any idea what's going on here?

Re: Cannot set wireless up

@rzrscm,
I would suggest starting your own thread. Although you have a not entirely dissimilar issue, it isn't at all clear that the issue is the same as for the OP. We don't even know what hardware the OP is using etc. Plus I'm assuming you've installed whereas I take it the OP is in the live environment.

I would say that you need to ensure one thing and only one thing is trying to manage your wireless connection. Otherwise they will fight over the interface. It sounds like you might be trying a bunch of different tools and probably not ensuring that the one is fully disabled before trying the next. If that's not it, though, start a new thread.

Re: Cannot set wireless up

It eventually worked after trying a few times. It's still pretty unstable, but I could at least get the installation running.

Re: Cannot set wireless up

I'm back again with a wireless issue, but this time with an HP laptop and rt2800 module.
I have no issue using wireless with preconfigured distributions (openSUSE, Fedora etc) OR with wifi-link from the Arch live image, but once I reboot into the system I cannot set the wireless connection up.
So using a wired connection, I installed gnome, networkmanager, the applet, wpa_supplicant and basically followed this tutorial:

http://evilshit.wordpress.com/2012/09/1 … th-gnome3/

Also installed rfkill and found out that the wireless chip is not blocked.
But when I try to connect using the gnome applet, it tells me that the wifi is unavailable.

If I do the same thing but with KDE and plasma-nm, it works.

Any ideas?
