    -k show kernel drivers handling each device
    -x show hex-dump of the standard part of the config space
    -xxx show hex-dump of the whole config space (dangerous; root only)
    -xxxx show hex-dump of the 4096-byte extended config space (root only)
    -b bus-centric view (addresses and irq's as seen by the bus)
    -d always show domain numbers

    resolving of device id's to names:
    -n show numeric id's
    -nn show both textual and numeric id's (names & numbers)
    -q query the pci id database for unknown id's via dns
    -qq as above, but re-query locally cached entries
    -q query the pci id database for all id's via dns

    selection of devices:
    -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] show only devices in selected slots
    -d [<vendor>]:[<device>] show only devices with specified id's

    other options:
    -i <file> use specified id database instead of /usr/share/misc/pci.ids.gz
    -p <file> look up kernel modules in a given file instead of default modules.pcimap
    -m enable `bus mapping' mode (dangerous; root only)

    pci access options:
    -a <method> use the specified pci access method (see `-a help' for a list)
    -o <par>=<val> set pci access parameter (see `-o help' for a list)
    -g enable pci access debugging
    -h <mode> use direct hardware access (<mode> = 1 or 2)
    -f <file> read pci configuration dump from a given file

    You've made a typing error. Please try again:
    Code:
    lspci -nn | grep 0280
    That's lower-case for LSPCI and then a space -NN then the pipe symbol | which is on the right side of my US keyboard on the same key with \; followed by 0280. It should give a description of your exact wireless device, like this:
    Code:
    chili@LAPTOP60:~$ lspci -nn | grep 0280
    03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6200 [8086:4239] (rev 35)
    Of course, your device is probably different.

    Please try again.

    Please try this:
    Code:
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1
    Is it a bit faster now? If so, we'll write one quick file and make it permanent.

    after those commands phy0 is still hard blocked:

    Code:
    0: ideapad_wlan: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    1: ideapad_bluetooth: Bluetooth
    	Soft blocked: no
    	Hard blocked: no
    2: hci0: Bluetooth
    	Soft blocked: no
    	Hard blocked: no
    3: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    the switch on the front side of the laptop is on. after i pressed Fn+F5, only wlan and phy0 is soft blocked.

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

    	Soft blocked: no
    	Hard blocked: no
    3: phy0: Wireless LAN
    	Soft blocked: yes
    	Hard blocked: yes
    then i pressed it once more and only phy0 hard blocked stays

    Code:
    0: ideapad_wlan: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    1: ideapad_bluetooth: Bluetooth
    	Soft blocked: no

    Let's make it permanent. Please open a terminal and do:
    Code:
    sudo gedit /etc/modprobe.d/iwlwifi.conf
    A new empty file will open. Add just one line:
    Code:
    options iwlwifi 11n_disable=1
    Proofread, save and close gedit. Now unload and reload the driver:
    Code:
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi
    Is the wireless now working as expected?
