Ubuntu – “Wireless disabled by hardware switch” after suspend and other hardware buttons ineffective – how can I solve this

keyboardshortcut-keyswireless

I have recently purchased a Novatech nFinity N1410 laptop and am having problems with the wireless, which

sudo lshw -C network

tells me is Centrino Wireless-N 2230 and using the iwlwifi driver.

The problem is that after the device has been suspended, I am not able to get the wireless working again without a restart. The network indicator states that the wireless disabled by hardware switch.

Though Fn+F2 is meant to be the wireless switch,

xev

tells me that the system doesn't see it as anything at all when I press this hardware combination. Also, though the brightness up/down buttons work fine, the volume up/down buttons do not work either.

What can I do to fix this? I am running Ubuntu 12.10 with all available updates installed.

I've been looking into buying one of these and have been looking for potential problems, looks like your solution can be found in the novatech forums:

Simply created a new file called brcm.sh

Inserted the below code and save:

#!/bin/bash
# Simple bash script to fix resume from suspend issues...
# Place this script in /etc/pm/sleep.d/
# then chmod +x /etc/pm/sleep.d/brcm.sh

case $1 in
  hibernate)
    /sbin/modprobe -r brcm80211
  ;;
  suspend)
    /sbin/modprobe -r brcm80211
  ;;
  resume)
    /sbin/modprobe brcm80211
  ;;
  thaw)
    /sbin/modprobe brcm80211
  ;;
esac

Placed it in /etc/pm/sleep.d/
Made it executable:
```
sudo chmod +x /etc/pm/sleep.d/brcm.sh
```

Is the module asus_nb_wmi loaded? Check:

lsmod | grep asus

If so, please try a driver parameter:

sudo -i
echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
exit

Reboot and see if the Fn+F2 behavior is changed.

If the above does not work, redo it again but replace asus_nb_wmi wapf=0 with asus_nb_wmi wapf=1, and if that does not work, replace it with asus_nb_wmi wapf=4 instead.

Ubuntu – Hardware wireless switch has no effect after suspend and 13.10 upgrade

Well, I had installed Ubuntu 13.10 on a new machine but messed my network setting up.

I installed gksu
I ran
```
gksu gedit /etc/network/interfaces
```

Edit the file with:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
# auto eth1

# iface eth1 inet dhcp

then just save it.

Just to make sure everything is ok

please check your dhcpd.conf file found in /etc/dhcp/dhcpd.conf to make sure

option domain-name "example.org";
option domain-name-server ns1.example.org, ns2.example.org;

default-lease-time 600;
max-lease-time 7200;

do not have # before them.

Now restart your system and I hope it works just like mine did.
