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)
