Wireless showing but fails to up/dhcpcd – Arch Linux

After my installation of Arch Linux I had some trouble using my wifi card which was working while I was running the live CD. What was strange was that the card would show up in iwconfig and ifconfig -a but not ifconfig It turns out I needed to install the wireless drivers and here’s how I did it:

Error:

ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory

dhcpcd wlan0
dhcpcd: version .2.2 starting
dhcpcd: wlan0: up_interface: No such file or directory
dhcpcd: wlan0: waiting for carrier
dhcpcd: timed out

Find out what card you are using:

lspci | grep Network
04:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Install: iwlwifi-3945-ucode-15.32.2.9-2-any.pkg.tar.gz

If you don’t have access to a wired connection, check out this guide to installing packages from the Arch Linux cd.

Once you get it up and running, updating via pacman (-Syu) will probably replace these drivers for newer ones which continue to work.

    Sorry men, but, what if my driver is already installed but the same message appears:
    dhcpcd: wlan0: waiting for carrier
    dhcpcd: timed out
    What should I do?
