This is maybe a disk or filesystem issue. Are other commands executed properly? Any errors on dmesg?

The device is a RT-AC3100 router. It has been working flawlessly for over 2 years. My other devices using wireless do not have any proplems connecting/

I don't know anything about the error message, but you could try power cycling, or rebooting, the router.

Done that before posting. Driving me crazy. Google search doesn't help.

You could start with explaining where you see this message, what you do before this message appears. Are you using wicked or NetworkManager or something else.

Educated guess is that to bring the wireless interface up it has to be associated with the access point which means this message is probably the consequence of a failed association. Also the subject of your post says "discovery failed" but there is absolutely nothing about "discovery" of any kind in your message.

yes the discovery failed. I have 8 other devices that do nothave any trouble accessibng it with the sames Network Name (ESSID) and mode/password. Thanks, -- Boyd Gerber 801 849-0213 ZENEZ 1042 East Fort Union #135, Midvale Utah 84047

I was wrong. It is possible (and likely necessary) to set device up before doing anything else. So it sounds like device issue. Reboot, and post full output of "journalctl -b" (upload to https://susepaste.org).

Also the subject of your post

yes the discovery failed.

It does not even attempt discovery, so discovery most certainly cannot fail when it is not even started.
