Well, your research should have shown that the 8187 chip is an 802.11g version, 
while the 8188 works with 802.11n. That should have given you a clue that the 
driver would be VERY different.

What kernel are you using? If you want the latest version of wireless code, you 
should be running the version found in the git repo at
git://git.infradead.org/users/linville/wireless-next.git. Your next-best option 
would be to get the bleeding-edge version of compat-wireless and build it for 
your current kernel.

There is a bug in rtlwifi that affects monitor mode in rtl8192cu, rtl8192ce, 
rtl8192se, and rtl8192de. I think it is fixed by the attached patch. At least 
monitor mode works here after the patch is applied. Please let me know if it 
works for you.

Larry
