Cannot get wireless network after suspend

Question

I've been working on an issue of calculation for months, but I can't get my wireless card to work. It always shows to me : Device not ready.

My laptop is Acer 4750g with Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) and the Ethernet controller is Broadcom Corporation Netlink BCM57785 Gigabit Ethernet PCIe.

I've tried

sudo service network-manager restart

but nothing changed.

After that, I've updated my wireless card diver from http://www.broadcom.com/support/license.php?file=570x/linux-3.118k.zip

And I got :

Settings for eth0:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Half 1000baseT/Full

                   drv probe link timer ifdown ifup rx_err tx_err

Does anyone knows how to fix the problem?

Try this (Problems with networking after suspend) or this (How to restart the networking service?), there should be something in all the solutions what can help you.

No, I've tried bash and restart network-manager already. It does not work for me. Thank you for the reply. – Laurent Dec 17 '13 at 11:48

I have the same problem and it's solved by removing and immediately reinserting the modules for the wireless.

sudo rmmod rt2800usb && sleep 3s && sudo modprobe rt2800usb

or

sudo rmmod ath9k && sleep 3 && sudo modprobe ath9k

Notice that this are the commands I use in my laptop and in my desktop. You'll need to find out which modules your wireless uses. I think by your post you're using a Qualcom Atheros like mine, so try the second command first.

Good luck!

Thank you for your reply. I choosed the second command, and nothing seems changed. I've already add in /etc/modprobe.d/ath9.conf to close the wake on lan by echo > – Laurent Dec 18 '13 at 12:56
