I don't have your NIC, but in a laptop I post this in I get: |

========================================= |

So in my card I have: "parm: power_save:enable WiFi power management" which |
| 68 |
is by default disabled. If I wanted to enable this parameter I would need to |
| 69 |
use a boolean term, e.g. 'true', or 'on', or '1', or 'enable'. Yours would be |
| 70 |
similar, but the exact parameter would be revealed when you run 'modinfo |
| 71 |
<your_module_name>' |
| 72 |
|
| 73 |
Then call this parameter when you modprobe the module. For example: |
| 74 |
|
| 75 |
modprobe -r <your_module_name> |
| 76 |
modprobe -v <your_module_name> power_level=0 |
| 77 |
|
| 78 |
Look at dmesg or syslog to see the result of your incantantion. |
| 79 |
|
| 80 |
If this solves your problem you can permanently define such a parameter in |
| 81 |
your /etc/conf.d/modules. |
