|
|
Hi guys,
I updated my kernel to 3.7.9 and now I am having issues with my wireless card.
rfkill list
Code: |
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
|
which should indicate a physical switch. The only switch I have ever used is "fn+F11" and that didnt help.
rfkill unblock all didnt help either.
I went through the kernel configuration at http://en.gentoo-wiki.com/wiki/Iwlwifi (just in case), but that didnt help.
lspci -v
Code: |
02:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
Subsystem: Intel Corporation Device 1001

Memory at f4100000 (64-bit, non-prefetchable) [size=8K]

Any idea?

You seem to have done your research. I would suggest you double check if the ``wireless power management enabled by default`` option in the kernel is enabled ? Otherwise if rfkill is compiled in your kernel, i dont see why it should be locked like that.
If you dont mind a kernel compilation and unstable you could try bumping up the kernel version. |

Hi jpc22,
Thank you for the reply. I just tried kernel 3.9.10 and no luck. I think I must be missing something big....
Do you mean:
Network support -> wireless -> enable powersave by default ?
I tried with and without it, but no luck. |

you could try wavemon in command line to check if your card gets some signal. |

Update: after the udev-200 update my wireless card stopped working. I undid the changes suggested by DONAHUE and now it is working again. I had to reboot the box twice because after the first boot the system wouldnt stop scanning addresses; on the second boot all was good. |
