Wireless on USB key - wpa_supplicant fails pre-shared key, not on ISO

Hello.  First post here.

I've installed Arch on a USB key--not the ISO live-cd, but a full, bootable OS install, as per the Wiki "Installing Arch Linux on a USB key".  It boots just fine on a desktop, a laptop, and a Chromebook in dev-mode; however, when I try to activate wireless on the laptops via wpa_supplicant, it fails with error:
"wlpXs0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect".

I tired to activate wireless thusly, as root:
ip link set DEVICENAME up
ip link (shows as "up")
wpa_supplicant -i DEVICENAME -c <(wpa_passphrase MY_SSID MY_KEY)

And then I get the error I described.

But when I boot my laptop(s) from an ISO "live" image.  I can issue the above commands with success, then use dhcpcd to obtain full wireless connectivity.  I am issuing my wifi key/passphrase correctly every time.

Is there some other package or configuration item I need?

Thanks!

Ok, nevermind; I got it working.  I wasn't having luck with wpa_supplicant, but I tried NetworkManager:
nmcli dev wifi connect MY_SSID password MY_KEY ifname MY_INTERFACE

And it worked just fine.
