This card has been persnickety. I keep trying different options. Stock drivers are hit or miss (See the ping code block). Best result so far has been compiling from realtek proper, although there are still stability issues.
If one does "modinfo rtl8192ce" you get a block of info called srcversion. I have found 4 different ones so far. Searching for "what does srcversion mean" hasn't led me to anything which would give any hints as to which is the latest(greatest).
old version----mint original driver 3.2.0-27/29

Firmware has no version info I can figure out so I "md5sum rtl8192cfw.bin" and found 2 different ones so far.
Mint stock version
748944fbffd3b08b5b1929bb6c7fc537 rtl8192cfw.bin
kevin@hp-pos ~/Documents/compatwireless/debianfirmware_rtl $ md5sum *.bin
d41d8cd98f00b204e9800998ecf8427e rtl8192cfw.bin
It appears some folks have found stability with this card, I too would like to find stability since the crooks at hp want $$$$ for an atheros one. Mint Maya 64 bit gnome. What I am trying to do, is not try things twice, but am not sure the srcversion and md5sum are the correct way. If anyone has any suggestions, pointers and other versions to try I'd appreciate it. I have also posted this in the Mint wireless forum.
Thanks!

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
