@Phaedrux one of my posts to you last night seems to be deleted or at least it's grayed out and I don't know if you saw it so I'm going to reshare the link I had in the post. Here it is...M115

@GBusy24 can you post a photo of the board?

GBusy24

@jay_s_uk unfortunately, I'm at work right now

GBusy24

@jay_s_uk may I ask what you would be looking for on the board and maybe I can help her memory. It is one of the newer boards with the external Wi-Fi antenna

jay_s_uk

@GBusy24 just checking that everything looks ok. as the wifi module appears to be working, the antenna is either not connected correctly or is not functioning.
I've seen cases of antennas not working correctly

GBusy24

@jay_s_uk I'm really confident that the antenna is connected correctly but I will mention that it is not mounted it is just laying near the board

jay_s_uk

@GBusy24 just laying around is fine. In that case, I would suggest changing the antenna

GBusy24

@jay_s_uk okay, but who will sell me just the antenna? I have two because I have two new boards. Maybe I should try the other antenna off of The Other Board

GBusy24

@jay_s_uk I will say that when working with the other board the green light on the Wi-Fi module would blink constantly where I get nothing out of this current board I'm working with

jay_s_uk

@GBusy24 yea, try the other one.
you can get antennas off amazon easily enough. search for a U.FL Antenna for wifi

GBusy24

@jay_s_uk okay thanks

GBusy24

@jay_s_uk I've now switched out the antennas, but still in same condition. No connection. Scratching my head. Here's a pic of the board. Is it a mistake to wire everything up before connecting? I know I've done this before successfully.20250415_191452.jpg

GBusy24

@jay_s_uk I set my network ...........it remembers it and M587 confirms. I send M552 S1 and get 'No known networks found".

M587 S"Greg's WIFI" P"**********"

Phaedrux

Just to confirm the situation.... Is this correct?

you have two old Duet 2 wifi boards that worked with the wifi network in question previously.
you have two new Duet 2 wifi boards with external antenna that both show No known networks found?

The network in question is a 2.4Ghz network?

Can you test in access point mode to remove your network from the equation?

https://docs.duet3d.com/User_manual/Reference/Gcodes#m589-configure-access-point-parameters

GBusy24

@Phaedrux The answer is yes to all 3 of your questions. It's morning here and I'll try that when I get home from work.

droftarts

@GBusy24 Does your WiFi network name actually have an apostrophe in it? You're sending:

M587 S"Greg's WIFI" P"**********"

But the remembered network has no apostrophe:
Remembered networks:
Gregs WIFI IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

If you need an apostrophe, put two apostrophes in, because it's used to signify a lower case letter in the M587 command. As it says in the M587 notes:

Use two single quote characters to represent one actual single quote character in the password or in the SSID. For example, if your SSID is "Pete's network" then enter "Pete''s network".

If that doesn't work, you can get the Duet to scan for networks, which will also check if the WiFi is working. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m5871-start-network-scan

From the YAT terminal, send:

M587.1

Wait for a few moments (30 seconds should be fine), then send:

M587.2

This should show any WiFi networks it has found.

@droftarts Aha! Good to know. Thanks,
