For the most part my wifi chip stays soft blocked. The only time I can manage to get it unblocked is when the wlan0 interface is hard blocked. I am able to: - soft block the interface - hard block the interface - hard block and softblock the interface I am not able to: - soft unblock and hard unblock simultaneously. I needed to do a fresh install of Gentoo Linux on a new hard drive. I don't have access to the old hard drive at the moment, but wifi did work on this older install of gentoo linux.. I am using the iwlwifi driver and firmware that are part of Gentoo. After I couldn't get wifi working I installed Windows 7 and the wifi works fine when I boot into Windows 7. I have looked many places for a solution and other people have run accross this problem but none of their solutions work for me. Here are some of the things that I have tried that have resolved this problem for others, but not for me: - unload and reload the iwlwifi module - disable rfkill and bluetooth in the kernel - boot with the hardware wifi switch off - boot with the hardware wifi switch on I have these kernels installed and ready to run on the new harddrive they all exhibit this same behavior: linux-3.6.11-r2 linux-3.7.10 linux-3.7.10-r1 linux-3.8.5 linux-3.8.6 I started out with linux-3.8.5 on this new harddrive. Wifi was working fine with linux-3.7.10-r1 on the old harddrive (same machine). If anyone has any insight into how I might solve this problem I would really appreciate a push in the right direction. Thanks - Darwin Below I've given a record of some of the commands I've tried to use to unblock rfkill and some info about my system: # iwconfig wlan0 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off # ifconfig wlan0 up SIOCSIFFLAGS: Operation not possible due to RF-kill # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no # rfkill unblock all # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no PRESS HARDWARE WIFI BUTTON, LED CHANGES TO ORANGE-OFF # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes # rfkill unblock 0 # rfkill list all 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes PRESS HARDWARE WIFI BUTTON, LED CHANGES TO WHITE-ON # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no PRESS HARDWARE WIFI BUTTON, LED CHANGES TO ORANGE-OFF # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes PRESS HARDWARE WIFI BUTTON, LED CHANGES TO WHITE-ON # rfkill list all 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no portion of dmesg output [ 3.636945] iwlwifi 0000:25:00.0: loaded firmware version 9.221.4.1 build 25532 [ 3.666672] cfg80211: World regulatory domain updated: [ 3.666676] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 3.666680] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 3.666735] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 3.666738] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 3.666780] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 3.666784] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) ...
