New Board Can't Connect to Wi-Fi.
-
First, THANK YOU for accepting me into this forum. It's greatly appreciated!
Second, please forgive me if this has been answered before, but I've searched and can't find the answer.
I just purchased a Wifi-Duet and got it yesterday. I used the supplied mini-USB to connect it to YAT on my computer. When I go through the steps to connect my board (M115 shows firmware 1.19.2, M552 shows "idle," M587 S"MY ACTUAL NETWORK NAME" P"MY ACTUAL PASSWORD") it goes well until the M587 S1 command. At that point I get "ok<lf>WiFi reported error: no known networks found<lf>Wifi module is idle<lf>"
Am I doing something wrong? Is the module malfunctioning? My router is 2.4MH and functioning with every other piece of equipment I have.
Thanks in advance for your help!</lf></lf></lf>

I presume you mean until the M582 S1 command, not M587 S1. I suggest the following:
1. Check that your router is configured to provide a network on the 2.4GHz WiFi band. The Duet WiFi does not support 5GHz.
2. Run
M577M587 with no parameters to list the configured WiFi networks, and check that the SSID shown is exactly the same as the one your WiFi network transmits on 2.4GHz, as shown on your smartphone if you scan for WiFi networks. SSIDs are case-sensitive.3. If the SSID is exactly correct then it is probably a signal strength issue. See https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors#Section_How_to_improve_RSSI.

Thanks for the help, DC42.
I ran the M577 command and got the following: "ok<lf>" Nothing else. I confirmed that my network is running at 2.4 GHz and that signal strength is excellent with a link speed of 1.44 Mbps on my cell phone. Any other thoughts on what I can do?
Thanks again.</lf>

I'm sorry. I meant M587.

This post is edited to add correct information:
Sadly, no joy.
When I use the 587 command, I get the following: "Remembered networks:<lf>TNCAP2FCC19<lf>My Network Name<lf>your=network-My Network Name Fa<lf>your-network-My Network Name Fa<lf>My Network Name <lf>My Network Name 2<lf>ok<lf>"
When I type the 552 S1 command, I still get: "ok<lf>WiFi reported error: no known networks found<lf>Wifi module is idle<lf>"
Hope I'm not being dense…</lf></lf></lf></lf></lf></lf></lf></lf></lf></lf></lf>
-
The latest: now an M587 command reports "M587: Failed to retrieve network list<lf>ok<lf>" This is after an M552 command that shows WiFi module idle. Seems like I have a defective board. Anyone else have any ideas before I return the board as defective?</lf></lf>

Please run M122 and check that the versions of main firmware (listed near the start of the response) and WiFi firmware (listed under the "Network" section) are compatible.

I had Firmware version 1.19.2 but upgraded to the latest 1.21 via SD card in the hopes that would help. When I run M122 I get the following:

I noticed that in my last post, I exceeded the number of bytes per line which truncated the command reply. Here is the full display with the M122 command:

Please put LF as line ending (<eol>) in YAT, this will give you proper printouts</eol>

You are running main firmware 1.21 but WiFi firmware 1.19.2. Please upgrade your wifi firmware to 1.21. As you can't connect via WiFi at present, you will need to move the SD card to a PC, copy the new DuetWiFiServer.bin file to /sys, eject or safely remove it, put the card back in the Duet, restart the Duet, and send M997 S1.
After that, if you run M122 it should report "WiFi firmware version 1.21" in the Network section.

Sadly, still no joy.
I updated both firmware and wifi drivers to 1.21.

My wifi network has an apostrophe in its name. Perhaps that could that be the problem? Any additional thoughts? At this point I'm close to stumped…

Never trust an apostrophe and anything to do with computer naming.
-
Apostrophe in a quoted string forces the following character to lowercase. So you need to use two apostrophes to represent one, in both SSIDs and passwords.
I suggest you send M588 "*" to delete all those dud remembered networks, then send the M587 command using two apostrophes in the SSID this time. Then send M587 without parameters to check it is remembered correctly.
-
Huzzah! That was the issue; a silly little apostrophe in the network name. My Duet Wifi is now connected to my network.
A big THANK YOU to all who helped, but especially to you dc42 for you patience and generosity with this issue!
-
No problem, it was you who suggested the apostrophe might be the problem and made the diagnosis easy. I've updated step 7 at https://duet3d.dozuki.com/Guide/1.%29+Getting+Connected+to+your+Duet/7?lang=en to cover the case of apostrophes in the SSID and password.
