To clarify (fix):
Check your rtl module with "modinfo 8*****" and you'll see it's still using stock.
On linux if you run "make modules_install"
and copy the /lib/modules/4.4.2-* folder (ignore the symlinks errors) to RemixOS /lib/modules - they should work.
Alternatively (pretty sure it would work) - run "modinfo *" on your module to check for dependencies - then find/copy/replace the relevent .kos (i.e. drivers/net/wireless/realtek/...)

I think stock/lwfinger might report different author/version
I'm compiling a version with lwfinger's rtlwifi_new on RemixOS via Ubuntu chroot at the minute, will post when done...
