The out put of ifup:
ifup wlan0
Determining IP information for wlan0... failed; no link present. Check
cable?
I have installed rfkill and unblocked all interfaces. now rfkill list shows
1: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
2: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
3: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no
4: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
9: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
now dmesg output have a last line like
ADDRCONF(NETDEV_UP): wlan0: link is not ready
Now iwconfig shows
iwconfig
lo no wireless extensions.
p8p1 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=17 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
vboxnet0 no wireless extensions.
virbr0 no wireless extensions.
ppp0 no wireless extensions.
It seems that it is trying to enable wlan0 but doesn't succeed.
I have already turned on the wireless on another laptop. But still it
doesn't make any progress
Thanks,
