[solved]WiFi problem on Lenovo Ideapad

Hey!

I've recently bought an Lenovo Ideapad (specs: i7 2670qm, 6gb ram ddr3 @ 1333mhz, nvidia geforce 540M with optimus enabled and 500gb hdd). I have arch installed and running for a week or two so far. I've encounter many problems (like no microphone or no sound control using keyboard (Fn + appropraite button)) and have solved the majority of them. But the main problem remains unsolved: WiFi connections. At first, WIndows 7 was installed and I could connect to my WPA2 WLAN smoothly but now wicd cannot even search for wifi networks.

Outut of lspci | grep -i net is

03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)

I read some topics and tried to mess with rfkill.

So rfkill list all shows me:

0: ideapad_wlan: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
when i press fn+button for wifi rfkill list all is like:

0: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

I've tried also to use rfkill unblock all and get this:

0: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: ideapad_bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes


I guess that the hardblock is the problem, but i cant do anything. If you want the output of any command let me know, and thanks for your time!

Re: [solved]WiFi problem on Lenovo Ideapad

Hardblocks are either physical switches on the device (a toggle switch on the side), a key pairing such as Fn-F3 or some such, or a bios setting.

Hopefully you will not have the issue of freezing when you try to use wireless after removing the hardblock.  If you do we can work through that, but step one is to find out which of the three options is blocking and reenable it.

Well, here I upload photos of my bios sections (seems fine to me).

Also, laptop has a switch (http://i.imgur.com/cNDnU.gif) , which look like the photo below. When the "thing" is on the right (the side with the computers surrounding by wireless waves) rfkill list all gives:


0: ideapad_wlan: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
and when i move it to the other side the same command gives:


0: ideapad_wlan: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: yes
2: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes.

Re: [solved]WiFi problem on Lenovo Ideapad

Hi,

I am not sure if this will help you, but on a Lenovo Z570 I had to do the following:

rc.d stop network
rmmod acer_wmi
modprobe acer_wmi

rc.d start network
rmmod -f acer_wmi

echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf

Ok, so maybe this script is a bit outdated (havent blacklisted modules on Arch for a while), but you get the idea: blacklist the module acer_wmi.

Also, the switch would sometimes give me problems (even after blacklisting) but I could always fix it by restoring the BIOS to default configurations.

I rebooted , set bios settings to deafult and logged in. Then Wifi worked! (I have already blocklisted acer_wmi but nothing has happened).

Thanks you two for helping.
