Subject: issues with RTL8188CE device and rtl8192ce driver

I have been having consistent issues with certain networks with my
RTL8188CE device and the rtl8192ce driver (using kernel 3.8.13). I am
running Gentoo linux and use NetworkManager to manage connections. I
can utilize many networks fine, but some networks enter a
connect/reconnect cycle where the device connects (and gets an IP/DNS
info), but as soon as I try to actually transmit anything it
immediately disconnects.

When I look at /var/log/messages, I see this pattern happening a lot
around the time the connection fails:
wlan0: disassociated from 00:18:0a:36:83:36 (Reason: 2)
cfg80211: Calling CRDA to update world regulatory domain
wlan0: deauthenticating from 00:18:0a:36:83:36 by local choice (reason=3)

(sometimes it says "Calling CRDA for country: US" instead)
