After performing a clean install of Ubuntu 16.04, my WiFi is trying to connect when disabled. My router WiFi is disabled so my system is hard wired via the ethernet connection. So I don't need the WiFi unless I'm out and about. Both the WiFi and the ethernet operate and connect just fine so there is no problem with the actual connectivity. The hardware works.

However, with the wired ethernet connected, I disable the WiFi via the network indicator in the panel. After the Upgrade, while disabled the WiFi still continues to seek a connection, which because of the router and my location, it can barely detect. So I get constant notifications that I don't have a connection, then I do, then don't, etc.

What could be happening such that with 14.04 the WiFi was disabled when disabled but now with 16.04 disabled is not disabled although it says it's disabled. There's no hardware switch to enable or disable the WiFi and the keyboard function toggle has never worked. It's just permanently "on" and does nothing which is fine with me.

I have an HP ENVY 17 Laptop and the wireless device is an Intel Dual-Band Wireless 3160 (rev 83).

My networking info is are as follows:

If "fn+f12" isnt working it might be worth asking HP how you can fix that? Might be a simpler process?

Other wise you might need to use a work around, I found the answers and links here to be helpful:

How to switch off wifi on startup or from the console

The only issue here is you'll need to undo it when you want to use the Wifi again... good luck!

  • Thanks Dreadlocked Sp4rtn. It's a work around but not really getting to the heart of the issue. I know how to turn it on and off. It's still seeking WHEN it's turned OFF. Which means that no matter what I do I can't seem to actually turn it off. That's a different issue. However it seems to have stopped after the last update. SO who knows what it was. Thanks anyway. – Exomancer Aug 19 '16 at 5:01
