"No known networks found" error

I'm guess the radio is okay then, hopefully its doable to sort out what is wrong with the firmware.

Three possible reasons for "No known networks found":

You have hidden the SSID in your router configuration. If you do that then you must specify the SSID you want to connect to in the M552 S1 command.
You have mistyped the SSID in the M587 command. Run M587 to list known networks and check that the one in the remembered list matches exactly the one that the router is transmitting on 2.4GHz.
The chosen network signal is too weak where the printer is. Move the printer into the same room as the router and try again. If that works, see https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors.

I read the thread as it having another Duet working under the same conditions; was I mistaken?

I did have a clone board working from the same location previously. It went into another machine, and I bought a genuine Duet to replace it. My SSID is not hidden. I've tried quite a few times to connect, however I'll try moving closer temporarily.

Here is M587:

Thats what I thought; could you just make sure there isn't a difference in the rrf or wifi firmware between the two boards before/after making the swap?

Here is my M115

M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-02-09b1

How can I check the wifi version? I have ran M997 S1 on version 1.23, I saw the whole install progression without any issues.

its part of the M122output, way down at the bottom.

Okay, I suppose it errored out in the M112 i ran earlier.
Now that i'm in AP mode, I can see my wifi version is 1.23

=== Network ===
Slowest loop: 8446.02ms; fastest: 0.00ms
Responder states: HTTP(0) HTTP(0) HTTP(0) HTTP(0) FTP(0) Telnet(0) Telnet(0)

WiFi -
Network state is running
WiFi module is providing access point
Failed messages: pending 0, notready 0, noresp 1
WiFi firmware version 1.23
WiFi MAC address 86:0d:8e:b3:b4:93

WiFi IP address 192.168.0.1
Connected clients 0

So now that I know I'm on 1.23 & 2.05.1, what else can I do? I did a speed test from my phone where my printer is located and I am getting 108 mbps/18 ms, i'm positive it's not connection strength.

Just figured it out. Nothing wrong with the board.

I had to reset my routing and AP configurations on my Ubiquiti network hardware due to a corruption or something, just recently. I didn't realize I had specified this time to separate my 2.4 and 5Ghz SSIDs. Now my 2.4Ghz SSID became named Matt Damon_IoT by default, while I was asking the board to try to connect to the 5Ghz exclusive SSID.

Specifying "Matt Damon_IoT" allowed me to connect with M552 S1.

I apologize to you guys for framing this as a duet issue, but at least this can perhaps be a new part of the questionnaire if guys pop up with this problem again, haha.

it would have been it you'd said you changed any thing other than the Duet; anyways this probably why the Duet replacement is "difficult" - rarely anything wrong with the board;) All that ends well and all that jazz:)
