Please tell us more. What does your wireless do or not do? When you click the Network Manager icon, do you see networks? Can you click on yours and try to connect? Please open a terminal and run and post:

rfkill list all
iwconfig

Thanks.

You have every right to be upset if your new laptop doesn't work properly. I would be, too. Let's work together and fix it.

i have read about acer_wmi module and i see it, it is loaded but it shuoldnt be.

acer_wmi               23612  0 
sparse_keymap          13658  2 ideapad_laptop,acer_wmi
wmi                    18744  2 acer_wmi,mxm_wmi

another problem is that in my network settings i cant turn off the airplane mode.

i have found on the internet that someone had to install windows to activate the wifi card?! another say that the driver iwlwifi should be downgraded?

*i am now on mint, but it's the same problem i had on ubuntu. please help me!

Code:

acer_wmi 23612 0
sparse_keymap 13658 2 ideapad_laptop,acer_wmi
wmi 18744 2 acer_wmi,mxm_wmi

another problem is that in my network settings i cant turn off the airplane mode.

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.

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
