Tim,
I did the live test with the Dec. 14 build of 12.04 (64 bit). It
connected with my WNDR3300 with no difficulty. I tested all 4 modes
supported by the AP. All worked.
I assume that an installation would work the same as the live version,
but that is easy for you to test.

Here are the 3 modes I was able to successfully test on my WNDR3300 as
an open AP:
* Up to 270Mbps at 2.4Ghz
11N Channel: 03/2.422Ghz
in this mode only the 11N SSID is beaconed.
iperf: 11.2 Mbps average over 120 seconds, high of 26.2 Mbps, low of 6.71
* Up to 270Mbps at 5Ghz & 54Mbps at 2.4Ghz
11N Channel: 36 / 5.180Ghz
11G Channel: auto
in this mode only the G beacon can be seen (which makes sense)
iperf: 14.3 Mbps average over 120 seconds, high of 28.5 Mbps, low of 8.97
* Up to 130Mbps at 2.4Ghz
11N Channel: 03/2.422Ghz
in this mode only the 11N SSID is beaconed.
iperf: 16.0 Mbps average over 120 seconds, high of 28.9 Mbps, low of 7.44
This mode would not acquire a beacon using the rtl8192ce:
* Up to 130Mbps at 5Ghz & 54Mbps at 2.4Ghz
11N Channel: 36 / 5.180Ghz
11G Channel: auto
in this mode no beacon can be seen.
I verified using a MacBook Air under OS/X that the N SSID was
appearing on the 5
Ghz channel, but couldn't see the G beacon. Maybe its a bug in the
WNDR3300.
I had never used the "auto" channel setting before. When I set my AP to
the same configuration as yours (130/54 and 36/auto), it sent the
802.11n beacon in the 2.4GHz channel. The 11G SSID was not seen;
however, I could connect to the AP on channel 1. When I switched to 11G
channel 1, rather than auto, then I saw the 11G SSID in the beacon. I
then tested the 5G band using a Dell DW1450 (p54usb) dual-band device.
The 11N SSID was present on channel 36 using auto or channel 1.
There may be a bug in the WNDR3300 firmware. Sometimes when I switched
from channel 1 to auto for the 2G band, that band would beacon the 11G
SSID, and other times, it would beacon the 11N SSID. I have not
determined a pattern. The 11N SSID is always shown on the selected 5G
channel. I could, however, connect the RTL8188CE to whatever SSID the AP
was sending on the 2.4GHz band.
Curiouser and curiouser,
Larry
Yep - specifying a _fixed_ channel for 'Up to 130Mbps at 5Ghz & 54Mbps
at 2.4Ghz' allowed a connection using the G beacon. I have not verified
using a 5Ghz capable adapter that its also beaconing on channel 36.
