Is my DuetWifiServer.bin properly updated?

@phoenix the WiFi server version isn’t aligned to the RRF/DWC version. 3.5.0-rc3 was released with DuetWifiServer 2.1beta6, but as @jay_s_uk points out, there is a newer 2.1beta7 version that’s resolves some connection issues. I’ve been using this and haven’t had a connection failure (apart from poor WiFi signal, but that’s my WiFi location’s problem). So please try that, and report back if your connection problem persists.

@droftarts Thank you for the pointer - I have updated it but can't see a difference.

Can't see a difference in the version number, or can't see a difference in operation i.e. you're still getting the error messages?

@droftarts Version is now showing 2.1beta7.
No change in the behavior. It's mostly annoying when doing config work, as randomly the interfaces loses connection (and reconnects within a second), but it closes the edited config file wihtout saving obviously. -

Signal strength -44dBm, channel 1, mode 802.11n, reconnections 0
I notice it says it's on channel 1. This can cause problems if you're using a Duet 2 WiFi with an aerial that's built into the WiFi module PCB rather than an external one. From https://docs.duet3d.com/en/User_manual/Troubleshooting/WiFi_troubleshooting
Try changing the channel on your WiFi router. Most routers default to Auto, but can be set to use a fixed channel instead. The channels overlap, so it is common to use channel 1, 6 or 11. This may also help if another device is causing interference.
Particularly if using channel 1, change the router WiFi channel. Duets with onboard WiFi antennas may be more susceptible to interference from the Duet itself at this frequency. Try channel 6 or 11.Ian

Can you try the older 1.27 release to see if the behaviour remains?

@Phaedrux Version 1.27 does not bring any relief unfortunately.
I understand @droftarts point - I'll change the channel to 6 or 11 on the home wifi. Crossing my fingers !
-
@Phaedrux @droftarts on Channel 13 now (Europe, and much less congested than 11 or 6).
I believe it's gotten slightly better, but I still see disconnects at random (frequent) intervals. If i understand you right, this is caused by EMF? Is my last resort an external antenna?

@phoenix Interference can certainly be an issue. Microwave ovens, cordless phones, baby monitors, or noisy electric motors (eg old fridge), so have a look a look around the immediate area to see if there's anything that could be causing it.
It's also worth looking at the LED on (or next to, depending on Duet 2 version) the WiFi module when it disconnects, to see if it is actually disconnecting; the LED should be on constantly when connected, but will flash when it loses connection and tries to reconnect. If it is staying on constantly while you have the error, then it may be a firmware issue.
To test the Duet's WiFi itself, change it to AP (Access Point) mode. You can connect directly via WiFi, and see if you get dropouts then. See https://docs.duet3d.com/en/User_manual/Machine_configuration/Networking#configuring-duet-in-wifi-access-point-mode
Lastly, have a look at the router. Do any other devices drop out? Some routers try and move the Duet WiFi to 5GHz, rather than 2.4GHZ, but then fall back to 2.4GHz, which might cause a disconnection/reconnection. There may be an option in the router to fix the Duet to 2.4GHz.
