Problem with rtl8821ae not finding any networks

I recently installed arch on a Lenovo All-in-One (B50) which has a rtl8821ae wireless card. I cannot seem to scan any networks, but everything else appears to be working fine. Here are some relevant bits:

wpa_supplicant-wlp5s0.conf:

ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel

network={
        key_mgmt=WPA-PSK
        ssid="MY SSID"
        psk=1234567889...
}

wpa_supplicant -iwlp5s0 -c /etc/wpa_supplicant/wpa_supplicant-wlp5s0.conf -d:

I feel like I'm either missing something simple or this module is whack. I've fiddled with various modinfo params, to no avail.

Any ideas?

Re: Problem with rtl8821ae not finding any networks

As a sanity check, did you run a scan by hand?  Try sudo iw wlp5s0 scan

Edit:  BTW -- Welcome to Arch Linux smile

Re: Problem with rtl8821ae not finding any networks

Yep, it returns nothing. Debug output seems to be largely irrelevant except this oddity:

-- Debug: Received Message:
--------------------------   BEGIN NETLINK MESSAGE ---------------------------
  [NETLINK HEADER] 16 octets
    .nlmsg_len = 36
    .type = 2 <ERROR>
    .flags = 0 <>
    .seq = 1421583995
    .port = 1853883468
  [ERRORMSG] 20 octets
    .error = 0 "Success"
  [ORIGINAL MESSAGE] 16 octets
    .nlmsg_len = 16
    .type = 16 <0x10>
    .flags = 5 <REQUEST,ACK>
    .seq = 1421583995
    .port = 1853883468
---------------------------  END NETLINK MESSAGE   ---------------------------

Message type = "error" with a message = "success"? Not sure if this is normal or not

Re: Problem with rtl8821ae not finding any networks

Are there any other diagnostics I can do? I'm at a loss.
