[SOLVED] Another HP laptop 3160 wifi issue

Post by andrew66 » Tue Feb 06, 2018 10:16 pm

Hi Guy's,

Just a wireless networking question from a novice linux user.

I was given a 3 year old HP laptop with a dual band intel AC 3160 wireless chip. I have Linux Mint 18.1 Serena installed on it. Kernel 4.4.0-112-generic.
The unit has no wireless hardware on/off switch, just a software enable selector. It does have an airplane key but this makes no difference. There is no option in
the Bios to disable wireless. Every time I try to switch wireless on it instantly turns itself off. This seems to be a running theme with these chips. It is currently
connected by ethernet cable. I have tried a few solutions listed here and elsewhere over time all to no avail.

Then a few days ago while searching for something else I found a old 802.11bg USB wireless dongle. I thought I give this a go and plugged it in.
When I clicked on the network connection icon not only was the wireless dongle listed but the 3160 connection was also shown. I clicked on it and it connected
without issue. I could also remove the dongle once it was connected and it stayed connected. Once I disconnected the only way to get the 3160 connection
option to appear again was to insert the dongle. All the time the 3160 was connected the main wireless software on/off selector was showing off.

I'm wondering if this infomation offers any insight as to what might be happening
(why I cant select wireless on normally)

Thanks
Andrew

Re: Another HP laptop 3160 wifi issue

After doing some more searching on the forum I came across this advice which finally solved my problem.
Turn the kernel module acer_wmi off
1.7. A certain kernel module, called acer_wmi, causes problems on some laptops. Because it has been loaded when it shouldn't have been.

a. Launch a terminal window.
(You can launch a terminal window like this: *Click*)

b. Now check whether the module is loaded; copy/paste the following green command line into the terminal:

rfkill list all

Press Enter.

This command will tell you, how your wireless card is called. In many problem cases, it's called (among other things) like this:

1: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no

The clue is then, that it's called acer-wireless (which means that acer_wmi is loaded) and that it has a soft block.

In such a case, proceed like this:

c. Copy/paste the following blue command line into the terminal (you can copy/paste with the right mouse button, it's one line):

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

Press Enter and submit your password. Please note that the password will remain invisible, not even asterisks will show, which is normal.

d. Reboot your computer.
