This got closed on AskUbuntu because it wasn't Ubuntu enough for them.

I don't have any WLAN connections set up, and I always connect via Ethernet cable. However my computer has a small light on it that flashes to indicate network activity. For some reason this light keeps flashing, at extended random intervals, which is very annoying. I remember that I disabled it somehow on my old partition (Ubuntu, Mate), but I'm not seeing an option for it now.

Added: since asking I found an answer to the LED problem here: "Wireless indicator light flashing for activity on laptop keyboard" but I would feel slightly better knowing that I solved the source of the problem and not just the symptom.

Then I tried sudo rfkill block all. Will that solve it permanently? Is there a better way?

Remove the firmware and/or blacklist the relevant module... – jasonwryan Mar 2 '13 at 20:37
I don't know how to do that. – Wutaz Mar 3 '13 at 0:05
It depends on your hardware (a vital detail you omitted from your question). See the Arch Wiki Wireless page. – jasonwryan Mar 3 '13 at 0:36

I believe Mint is running NetworkManager, and that's what connects your wireless network.

Edit your wireless connection profile, there's an option called Automatically connection, disable that.

Yes, I have NetworkManager. The documentation for it is a huge mess. Does <code>sudo nmcli nm wifi off</code> do what I want? Because nothing in /etc/NetworkManager changed when I ran it. – Wutaz Mar 3 '13 at 19:05
Nevermind, I found the config in /var. Just when I think I'm starting to figure Linux out, it turns out to be even more screwed up than I thought. Thanks anyway. – Wutaz Mar 3 '13 at 19:08
@Wutaz no need to run nmcli, just open nm-connection-editor to edit that – warl0ck Mar 3 '13 at 23:58
