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:

Is there anything else I can provide?
