Lenovo IdeaPad Z570-1024D9U - Laptop (Wireless Help)

[divamvak]

basic display modes:
-mm produce machine-readable output (single -m for an obsolete format)
-t show bus tree

display options:
-v be verbose (-vv for very verbose)
-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

i also understood that i have this probem only in wep wifi

You've made a typing error. Please try again:

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:

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:

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.

[hrvooje]

Please try this:

sudo modprobe -r acer-wmi
sudo rfkill unblock all
rfkill list all

Any improvement? If so,we'll tweak one file to make it permanent.

after those commands phy0 is still hard blocked:

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.

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

	Hard blocked: no
2: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN

then i pressed it once more and only phy0 hard blocked stays

sudo modprobe iwlwifi 11n_disable=1

yes it seems to be a bit faster

[chili555]

yes it seems to be a bit faster

Let's make it permanent. Please open a terminal and do:

sudo gedit /etc/modprobe.d/iwlwifi.conf

A new empty file will open. Add just one line:

options iwlwifi 11n_disable=1

Proofread, save and close gedit. Now unload and reload the driver:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

Is the wireless now working as expected?
