ath9k

Comparing my results to the Wireless Network Configuration wiki I'm surprised I'm connected wirelessly. When I run lspci -v I see my wireless adapter as ath9k. However, when I dmesg | grep ath9k I don't get a result at all. When I dmesg | grep ieee80211 I do see my wireless, but as a ieee80211 phy0.

What am I missing? Thanks.

I'm not sure what you are missing - but I see we are missing all the output of the relevant commands - even the ones you mention running.

How about the following to start:

lspci -vnn | grep -i net
ip a
lsmod

I appreciate the reply. I did use -i and -A to grep earlier. But, per your request here it is:

Just to make sure it's clear, I'm up on wireless - which is how I'm online right now. Just don't understand why dmesg is different from the wiki.

Your wifi is wlp3s0, and your kernel module is ath9k, etc. So it looks like to me it's there. You could iwconfig wlp3s0 to find out how fast it is operating at, and that it is in fact associated with the AP.

It's all associate. I just don't understand why my result differs from what the wiki says I should get.

What do you expect to see from dmesg? Which wiki page says you should see output?

Under "Check the driver status" section lspci outputs the driver, and then the second dmesg has you using grep with the driver name. When I grep my driver name I don't show any output via dmesg. Is that an issue with my system, did something recently change, or does the wiki need to be updated, or is this specific to my driver?

My adapter uses the same driver and there is nothing related to ath9k in my dmesg. Yet everything has been working just fine for over 3 years now since I've bought this laptop. No reason to worry.

The message in dmesg shows up as Atheros ARxxxx, which is the message produced by ath9k modules.

Which wiki page? The wireless networking configuration page?

If so, the suggestion to use dmesg is only if there is a problem with bringing the interface up. If you get an error in bringing up the interface, more information may be available via dmesg. There has been no error, there is no need to seek further messages.
