unable to configure the wifi during the fresh install dhcpcd time out

hi I am doing the fresh arch installation.
But I am not able to assign the ip address to my wifi card during the installation, the dhcpcd is in waiting for the carrier and its timing out. [https://wiki.archlinux.org/index.php/Beginners'_Guide#Wireless]

My wifi card is Qualcomm Atheros AR9285

command "wifi-menu wlp2s0"   has detected my wifi network and connected. But "dhcpcd wlp2ss0" is keep on failing. i tried below command also but failed:

# echo 'ctrl_interface=DIR=/run/wpa_supplicant' > /etc/wpa_supplicant.conf
# wpa_passphrase <ssid> <passphrase> >> /etc/wpa_supplicant.conf
# ip link set <interface> up # May not be needed, but does no harm in any case
# wpa_supplicant -B -D nl80211 -c /foobar.conf -i <interface name>
# dhcpcd -A <interface name>

i have searched the forum but didnt find a usable solution. Please help me

Re: unable to configure the wifi during the fresh install dhcpcd time out

Is it a wpa(2) network?

You should not need to use the "-D nl80211" flag to wpa_supplicant.  I'm not sure if it would make a difference, but (if it is a wpa network) I'd suggest running it without that.

Thank you Trilby for the response.

I am not sure weather it is a wpa(2) network. How to check.

I tried your solution, but the issue is not yet resolved.

Who's network is it?  Whoever set up the network would know, or you can find out by checking the output of an iwlist scan (or posting it to a pastebin site and linking here).

EDIT: you describe using the <passphrase> in one of the steps.  Where did you get the passphrase?

Re: unable to configure the wifi during the fresh install dhcpcd time out

its my home network only. and it is wpa2 secured [sorry now only i got the meaning of wpa2]

<passphrase> is the password i configures inthe wifi router. the network is working fine with other windows systems and smart phones

also this "wifi-menu" is finding the network and it is connected after I gives the passphrase.

thanks again
