In this notebook clevo W150HRM (with a reatek card: rtl8192ce : Realtek Semiconductor Co., Ltd.|RTL8188CE 802.11b/g/n WiFi Adapter [NETWORK_OTHER] (vendor:10ec device:8176 subv:10ec subd:9196) (rev: 01) ), runing kernel-3.3.4 with compat-wireless currently NetworkManager is not detecting any wifi network. And in notebook clevo M761SU (with a Realtek card 8187B), running Windows 7 Ultimate, it detects 6 wifi networks. Now if i run in clevo W150HRM the kernel-3.3.1 it will detect the same 6 wifi networks that are detected in clevo M761SU running Windows 7. Is the fix http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=eb641120479de7ee703fabb5e6ee0ec7947474ba an improvement? Or would it need some more tweaks, since i have turned the notebook clevo W150HRM it started by detecting 6 wifi networks, than passed to 3, then passed to 1, and now is detecting none. I know i have been insisting on this but its because i cant see here an improvement with last fix (just not to mention the problem with keyboard and mouse where i had to turn off power management), i just hope that my interventions can be seen as a try to improve things and not as criticizing anyone work. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
