Got a bookshelf system that has an Intel Wireless 3160 chip. My wifi is set up and works fine from 2 Macs, 1 Android and 1 Windows PC. The Linux machine won't detect it. This machine is an HTPC that runs a couple of web apps as well (for use on the local network).

This system is not new but these wireless issues made me think the previous install could be the problem so I did a fresh install of Ubuntu today. At the very least I'm running a very well supported flavor of Linux.

Things I have tried

$ lshw -C network
... ethernet interface up above
*-network
  description: Wireless interface
  product: Wireless 3160
  ... etc
  configuration:broadcast=yes driver=iwlwifi wireless=IEEE 802.11 [etc, don't know what's relevant]

I did download a driver from Intel and place it in /lib/firmware. I can't tell if iwlwifi is the new driver or the stock driver.

When I run nmcli dev wifi list I get:

$ nmcli dev wifi list
IN-USE BSSID SSID MODE CHAN RATE SIGNAL BARS SECURITY
$

So that tells me it's not seeing the wifi.

This answer suggested starting the supplicant service, but that didn't fix anything, still now wifi signals showing in nmcli list.

The wireless is not hard or soft blocked.

I installed ifconfig and ran it, it shows three interfaces: enp2s0, lo, wlp3s0. I was expecting a wlan0 in there from reading troubleshooting articles.

I've been knocking my head against this for hours now, I need help. I guess the easiest fix might be to just buy a wifi dongle. But it really seems like the onboard wifi should work and something is just not set up correctly.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
