Duet 2 Wifi No Known network found

CptCulp

So i have an older (2018) Duet 2 Wifi board, i just recently updated firmware to 3.2.2 (FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2.2 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-02-11)
However as the title suggests i cant get it to find my network
(WiFi reported error: no known networks found
WiFi module is idle)
Im only about 10 feet away from my router, and it is set to 2.4ghz. Ive also made sure the new wireless sid has been update (with m587, Asus Beta is the one im trying to connect to)
Remembered networks:
TNCAP2FCC19 IP=192.168.1.14 GW=0.0.0.0 NM=0.0.0.0
MY2525 IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0
ASUS BETA IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

Right now Im inclined to believe that because of order it is still trying to connect to my2525 which is no longer on the network. Or that my wifi on the duet board has failed.

With the wifi on the duet failed im unsure how to really check it, ive read some posts and some mention a blue light. When i connect solely with USB i dont see a blue light on the board, but when i connect with the PSU i do see a blue light, however im unsure if that blue light is wifi or if it something else.

Im completely lost and would like some assistance, im sure its something simple that im overlooking but im frustrated and im sure cooler heads and a fresh pair of eyes could help me. Im just trying to be able to connect to the Duet Web Control.

Try it without the space?

The use of special characters in the SSID cannot be guaranteed to work. In general it's best to avoid most special characters. Spaces, periods, dashes, underscores, and other punctuation is likely ok, but special characters on the number keys likely are not safe. (@#$%^&*). If you are having troubles adding your SSID, try a simplified version with only letters and numbers.

You can also clear all saved networks with M588 S"*" as it will try and connect to the network with the strongest signal.

Also send M122 and check your wifi server version at the end of the report. For firmware 3.2.2 it should be v1.25

@cptculp I have an UPS on my printer. Recently we had a power failure while I was working on it and I started getting this "no known network found" message, over and over. Had to clear it to type any commands, then I only had a few seconds before it came back. I wish I knew how to disabled it. It was accurate, because my normal WiFi connection was not up because the router was unpowered.

I also note that a half dozen or so messages appear in quick succession on the screen, but don't show in the log, when I turn the machine on. I can't catch what they say, but at least one looks like an error of some kind. Don't know how to look at them more slowly. They disappear fast.

You can send M98 P"config.g" to execute the config as a macro and you'll see any warnings or errors that might get missed at startup.

@phaedrux Ah, it's obvious now that you said that! Thanks!

Ok, so i cleared the saved networks, and had tried one with my current sid as the only one, then another sid with my current sid but no space ie;

Remembered networks:
Asus Beta IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

and

Remembered networks:
AsusBeta IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

Both of which gave me a no known networks found. As for the firmware version of the wifi using m122, I get this; WiFi firmware version 1.25.

Any ways i can troubleshoot to see if my wifi card on the duet maybe has failed?

then another sid with my current sid but no space

And you changed the SSID on the router too?

@phaedrux I did not, ill try that tonight when i get off work.

From memory, I am fairly sure that a SSID with an embedded space worked last time I tried it; but I haven't tried it recently.

Another possible reason for failing to connect it that the router is set to hide its SSID. If that's the case, you need to include the SSID name in the M552 command like this:

M552 S1 P"Asus Beta"

@dc42 Huzzah! the space in my ssid as well as connecting straight to it as suggested finally granted me access, WiFi module is connected to access point ASUS2g

Thank you all for the help, now i just nope no other little hiccups along the way as i get this thing up and running again. Thank you all again!
