Hi fellows,
After going through pretty much all forum posts on various wifi issues, I've landed here as none of the suggestions helped in sorting out my problem.
Yesterday I unpacked my new duet 3 mini 5+ and since then I haven't been able to generate an IP address that makes sense to access DWC. After a whirlwind of working around relevant suggestions on the forum, the closest I got to any success is having generated IP address 255.255.255.255 on Serial Tools (using Macbook Air) and clearly this is no success. Learning from prior posts, I'll try to save time by sharing as much info as possible.
First of all, I'm using my previous SD card with all the updated firmware 3.4.6 and system files cause guess what, the wifi on my previous duet mini 5+ stopped working out of nowhere a week ago not responding to any of the M552 prompts, hence the brand new duet I received yesterday and started playing around with. Anyways, below are a set of details and commands on Serial Tools hoping that it will help someone see something I'm not able to:
Everything is running at 9.4V FYI

- I'm connected to 2.4Ghz router at home
- I tried all of these steps with 3 other routers at work before coming home as last resort
- I flashed the wifi firmware a good 5 times using M997 S1 and each time with 100% upload success at 115200 baud rate.
- I went through the M552 S-1, S0 and S1 cycles multiple times. The wifi led (green) responds to the commands which is good I guess.
- However each time the IP address is generated as 255.255.255.255 after hundreds of:
WiFi module is idle
Error: WiFi module reported: network scan failed
WiFi module is idle
Error: WiFi module reported: network scan failed

So, I ran M122:

- Wifi version is up to date as can be seen above: WiFi firmware version 1.26
- WiFi IP address shows as bogus 255.255.255.255.
I also ran M111 but not sure what to make out of it?
M111

Then I decided to run the M587:
M587
Remembered networks:
TNCAPF2FD81 IP=192.168.1.14 GW=0.0.0.0 NM=0.0.0.0
ok
...which also doesn't seem right at all. This is definitely not the IP of any network I connected to. Seems bogus to me as I've seen several posts with similar "remembered networks".
Now the weirdest part comes. I took its word and assumed that there was a remembered network, so I tried sending the M588 S"*" absolutely using correct straight quotations (not curved). This is what I get:
M588 S"*"
.. yeah, so, nothing. And M587 still gives me:
M587
Remembered networks:
TNCAPF2FD81 IP=192.168.1.14 GW=0.0.0.0 NM=0.0.0.0
ok
So, as the last step, I reflashed with M997 S1, then got the wifi in idle mode with m552 s0, and confirmed with M552. Finally I tried adding the SSID and Password of my 2.4Ghz home network, which I do not have any non-alphanumerical characters in either.
M587 S”mynetworkssid" P”mypassword”
And I got no response to this either, after a long long wait.
I ran M552 S1, and M552:
M552 S1
ok
M552
WiFi module is connected to access point , IP address 255.255.255.255
ok
FINAL NOTES:
- Seeing other users having issues with their SDs and replacing the SD helping solve their issue in a few instances, I also tested with two other SD cards from my colleagues' duet mini 5+ which work perfectly on their machine, unfortunately results are similar.
- My final thought was the 802.11w Management Frame Protection settings on my macbook air (since it's a fairly new computer and I've also read people having issues with their macs due to to some network/firewall settings). However I couldn't find anything on my system related to this so this is still an open question.
- I tried replicating errors on Windows, other macs but all in all, no luck with all the debugging across various hardware.
I find it hard to say but perhaps I had a bad seed off the package? I purchased my duet mini 5+ from Filastruder. And sad to say that a lot of other posts mentioned the same vendor. I am still hoping for some north star to come and suggest another approach but otherwise perhaps I'm looking at a replacement?
Thanks for reading my lengthy post & any help is much appreciated!
