WiFi driver is not installed on Asus PCE AC68?

Solution 1:

Sorry that I have to add this as an answer, as I don't have rep to comment yet. Thanks to chili555 reply and racar comment I now have the PCE-AC68 working on my system, Ubuntu 15.04 on mobo ASUS A88XM-A by

sudo apt-get install bcmwl-kernel-source
sudo modprobe wl
sudo reboot

I wanted the card as I've upgraded my cable modem + wifi router to Telstra Gateway Max (rebadged Netgear) which supports dual band wifi. Link speeds specified as 216/292 Mbps. It's probably not ideally set up yet as I'm only getting about 30 Mbps - I note that it's 802.11abg connection from iwconfig:

wlan1     IEEE 802.11abg  ESSID:"Telstra226B"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 40:5D:82:47:F4:66   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

But at least it is working now, and faster than my old Netgear WN111 usb plugin :) So thank you again.

Solution 2:

Please run the command:

lspci -nn

Is your device this?

Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter (rev 03)

If so, it uses the driver bcmwl-kernel-source. If you still have the install DVD or USB, then you can find it and its prerequisite there. Navigate to pool > restricted > b > bcmwl and drag and drop the deb file to your desktop. Now navigate to pool > main > d > dkms and drag and drop dkms to your desktop. Now install both with:

cd ~/Desktop
sudo dpkg -i *.deb

Load the driver:

sudo modprobe wl

Your wireless should now be working. If it not as I described, please post your finding and I will edit my answer to propose a different solution.

Solution 3:

I used this method:

Go to Settings > Software & Updates > Additional Drivers

It loads for a few minutes and then shows your wifi device (Broadcast name) and then you can enable it.

Then you can sudo apt-get update. It works for me.
