Hi all, new to Arch Linux, but relatively experienced with Linux in general.
I recently did a fresh install of Arch on a desktop machine, and the primary way for this machine to connect is via a wireless PCI card.
I followed the instructions in the Wireless Setup wiki page and installed NetworkManager, and everything seemed to work just fine for about a day; I was able to connect to my office's wireless network on boot. However, our wireless router occasionally flips out and will drop all connections for a minute or so. The first time this happened, I couldn't re-connect to the wireless network, but rebooting solved the problem. The second time it happened, however, I was unable to re-connect, even after a reboot. All the other computers in the office can still connect just fine.
I've tried multiple different networking setups, including NetworkManager, wicd, netcfg, and manually connecting using wpa_supplicant. In all cases, when I try to connect to the network, I receive the following in /var/log/everything.log:
Jul 21 16:29:31 localhost kernel: [ 4300.253663] wlan0: authenticate with 00:02:6f:88:f0:14 (try 1)

Jul 21 16:29:36 localhost kernel: [ 4305.234866] cfg80211: Calling CRDA to update world regulatory domain
This repeats 3-4 times until whatever networking tool I'm using gives up and tells me that the password is incorrect (I know it's correct, of course).
If I try to connect manually with wpa_supplicant, I receive the following output in a loop:
Trying to associate with 00:02:6f:88:f0:14 (SSID='tig' freq=2462 MHz)
Associated with 00:02:6f:88:f0:14
WPA: 4-Way Handshake failed - pre-shared key may be incorrect
CTRL-EVENT-DISCONNECTED bssid=00:02:6f:88:f0:14 reason=0
My wpa_supplicant.conf was generated using wpa_passphrase, following the instructions on the WPA Supplicant wiki page. It looks like this:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
network={
ssid="myssid"
#psk="MyPSK"
psk=4d301fd204fc0e46d69ceb1c842af7321e5989823f0a56d73e9d72de814791ee
}
It seems to me this may be a driver problem since the issue is so consistent, but I don't know much about troubleshooting hardware issues in Linux. Any help would be appreciated.

Update: I came in to work this morning, and it connected to the wireless network perfectly. The only change from my previous post is that the computer was powered off overnight. Could the card be overheating?

...Could the card be overheating?
I'm not sure what is happening, but I would venture that overheating is probably not the issue. In my experience, thermal issues have not a problem for wireless cards.
