DUET 3 mini 5 wifi unstable

JabawokJayUK

I have found a problem where the wireless module will not reconnect to the wireless network, after a restart or power off / on cycle. The console throws a continuous loop of:

Error: WiFi module reported: network scan failed

I have tried reinstalling the firmware multiple times and am on the latest firmware. This is an error report rather than a request for help as I have bought the wired version to replace it with.

@JabawokJayUK what do you class as the latest firmware?
please post an output of M122

If you send M552 S0 and then M552 S1 from the PanelDue does it manage to connect?

JabawokJayUK

@Phaedrux Unfortunately, this does not fix it. Today, I booted the machine after being off all night. It came up and connected to the SSID, acquired its IP without issue and I successfully connected to the web GUI. Within 30s it dropped the wifi and was unable to connect again with the panelDue showing it no longer had a connection to the wifi:

I ran M552 S0/1 as requested from the Panel Due and that leaves it in the following state:

ERROR: WiFi module reported Unexpected WiFi state 'idle' while trying to connect

As you can see from the image below, the ariel is in plenty of space and the closest access point is <1m away offering coverage for a/c/b/g/n/ specifications.

Phaedrux

Can you show some photos of the antenna connection at the duet? Can you try reseating the connection?

Do you have a dedicated 2.4ghz SSID to connect to?

JabawokJayUK

@Phaedrux I have previously tried all of those options. Dedicated 2.4ghz SSID, and multiple tails / multiple antennas (2-10 dBi) both directly connected or with extensions to locate the antenna in better air. Its not a physical issue.

Its either a bad board or a firmware issue, and the solution to both is to move to wired. I didn't want it to be connected over wifi initially, as I intended to use it in SBC mode, so it wasn't an issue, and I had this wifi version spare. Still, now I intend not to use the SBC so replacing it with a wired version is the logical option.
