Broadcom BCM4313[14e4:4727] Wireless LAN rfkill phy0 hardblock[SOLVED]

I am having serious issues with my Broadcom BCM4313 and I am at the end of my rope with trying to get my wireless to work.  I have read many many posts on this issue but have yet to find a solution to my problem.

I have a lenovo S10-3t and the wireless used to work but at some point it stopped working.  I have tried both the wl drivers and the brcm80211 drivers and it still won't work, have made sure to blacklist and/or removed any irrelevant drivers.  I also made sure to update all the drivers and the b43 firmware.

Anyways here goes the relevant information.

Arch version running

uname -r
3.7.4-1-ARCH

Wireless NIC card info:

lspci -vnn | grep 14e4
05:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe [14e4:1692] (rev 01)
07:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
	Subsystem: Broadcom Corporation Device [14e4:0510]

At first glance everything seems OK...

iwconfig
wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off

          Power Management:on
          
lo        no wireless extensions.

eth0      no wireless extensions.

Don't think I have any conflicting drivers...

As far as I can tell driver is loading correctly...

dmesg | grep bcma

So I then try iwlist scan...

sudo iwlist scan
wlan0     Interface doesn't support scanning : Network is down

lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

Ok so if I try and put it up by saying sudo ip link set wlan0 up it says can not due to rfkill

So rfkill says...

rfkill list
0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

If I try and sudo rfkill unblock all nothing happens, if I try and turn the modem switch on and off, nothing happens...
basically at this point I am about to buy a usb dongle but if someone can help me out that would be great. 

Also, I don't know if this relevant but if I rfkill list before trying ip link set wlan0 up it says that there is no hard block.

Re: Broadcom BCM4313[14e4:4727] Wireless LAN rfkill phy0 hardblock[SOLVED]

Same problem here.  I can log on to my wireless network, but can't access the internet.  Have you made any progress?  MJ

Re: Broadcom BCM4313[14e4:4727] Wireless LAN rfkill phy0 hardblock[SOLVED]

I've encountered this problem on my broadcom device several times.  Maybe we have the same problem?
Try this:

# sudo rfkill all

Then, shutdown, unplug the power, and pull out the battery.  Hold the power button down for 20 seconds (not sure if this helps, but I did it anyways).  Plug the battery and power back in, boot, and hopefully your hard block will be gone.

Good luck.

Re: Broadcom BCM4313[14e4:4727] Wireless LAN rfkill phy0 hardblock[SOLVED]

I might have a slightly different problem actually.  rfkill list all shows Wireless LAN both soft and hard unblocked.  Also, Wicd sees the network, and I'm able to connect, but can't get any internet traffic.  How could I see internet, connect to my wireless network, but not be able to get any data?

PS:  ethernet does the same thing.  I can connect, but can't get any data from the web.

I've tried toggling wlan0 using "ip link set wlan0" down, then back up. Drivers look to be in order.

It started after the update this weekend.

Any ideas?

As you can see, no broadcom here, and I am writing from this machine connected to a wireless network.

Re: Broadcom BCM4313[14e4:4727] Wireless LAN rfkill phy0 hardblock[SOLVED]

Ok so I fixed my problem!!!!!!!  Finally after almost giving up hope I figured out what the problem was.  I tried both SpyChicken and sano's tips to no avail but I found this blog right here, that gave me the solution.  To quote the blog:
"
SIOCSIFFLAGS: Operation not possible due to RF-kill
The solution is a reboot. Hit F2 to enter bios, then F9 to reset, then F10 to save and exit. Your wireless should be working at that point.
"

Then at that point I just did sudo ip link set iwlan0 up and I fixed my wifi, for me broadcom module was not the problem but it seems there are some very strange quirks to broadcom nics and linux.

Actually the "quirks" are in Lenovo's bios.  I (and many other S10-3 not -t owners) had to completely disassemble my netbook to remove to bios battery to force a reset for a problem Lenovo is well aware of ... they just don't care because it only affects linux - the hardware toggle switch becomes a one way kill switch.  I have now glued mine in the on position.

EDIT: this is not a "flame" against Lenovo as overall I love their computers.  If I had to buy a new computer today it'd definitely be a Lenovo.  But on this one issue I think they have really 'mucked' up.
