Please note: use of this driver on Lenovo systems results in unpredictable fatal crashes on some systems! It's is *not* advised to choose this chipset.
Known problems:
* Connections randomly drop out after a few minutes (seems to be fixed in version 015) This problem has been observed with version 015 too. Realtek has been contacted about the problem. * When using WPA Enterprise, entire system will freeze after a few minutes, requiring reboot * Freezes also happen with Ad-Hoc mode from time to time
