Linux – Arch Linux – DHCP – Can someone diagnose this

Arch Linux Wifi Connection Issues

I am currently in the process of trying to install Arch i686 on an Acer Aspire One 532h (32 bit).

At this point I am still in the LiveCD environment and setting up the wireless connection. However, I am running into a problem with connectivity.

I guess I should say that I have already verified the compatibility for my network adapter.
Atheros AR9285
http://www.linuxquestions.org/hcl/showproduct.php/product/4446/cat/160

Also verified it from the Arch command line:

#lspci -k

02:00.0 Network controller: Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) (rev 01)
...
Kernel driver in use: ath9k
Kernel modules: ath9k


# iw dev

says my interface is wlp2s0 (it's the only interface available)

when i try to use:

# wifi-menu

I can select my SSID and enter my password and save the profile

# ip link show wlp2s0

3: wlp2s0: <NO CARRIER, BROADCAST, MULTICAST, UP> mtu 1500.......

# dhcpcd wlp2s0

dhcpcd[2191] version 6.4.2 starting
...   [2198] wlp2s0: starting wpa_supplicant
...   [2201] wlp2s0: failed to start wpa_supplicant
Line 1144: unknown EAP method 'SIM'
...
...
dhcpcd[2520]: wlp2s0: waiting for carrier
dhcpcd[2520]: timed out
dhcpcd[2520]: exited

I also created a file at /etc/wpa_supplicant/test.conf very simple consisting of basically the SSID and password not mentioning an EAP, WPA, WEP or any protocol.

 # wpa_supplicant -B -i wlp2s0 -c <(wpa_supplicant/test.conf)

Successfully initialized wpa_supplicant

 # dhcpcd wlp2s0

(I get the same error message as earlier.)

Not sure what I can do at this point. I verified the .sig on the ISO, verified that my network card is supported. Used the simple interface (wifi-menu), used the CLI to create a .conf and execute the wpa_supplicant manually. I am getting a hangup at the dhcp somewhere but not sure where I need to look to diagnose this problem.

Any suggestions?
