[Bug 902557] Re: 10ec:8176 Wireless not working in 12.04 for rtl8192ce (RTL8188CE)

$ md5sum /lib/firmware/rtlwifi/rtl8192cfw.bin
fd118c183ad9e11060a6e575b472280e  /lib/firmware/rtlwifi/rtl8192cfw.bin

Saw this and also noticed that I had another file (same name, but with
.bin.bak extension) that matched the md5sum @Larry posted, so I swapped
them around and ran

$ sudo rmmod rtl8192ce
$ sudo modprobe rtl8192ce

No noticeable difference, however. Here's the output from syslog,
filtered on the Reason 6 deassociations:

As you can see, the deauthentication still happens on a very regular
basis. The wireless connection is usable, but because of the packet loss
that results from the continual disconnects, it's incredibly slow. I'm
sitting here right next to the router and showing full signal strength.

Here's iwconfig:

Here's cat /etc/modprobe.d/rtl8192ce.conf:

options rtl8192ce ips=0 fwlps=0

Is there anything else I can provide?

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Precise:
  Confirmed

Bug description:
  Wireless no longer seems to work since I upgraded to Precise, it was working (albeit very flaky) ion 11.10, but it never seems to be able to connect to any access points since the upgrade.
  It can see all the available networks, but it can't seem to connect to any of them.
