WiFi disconnect errors
-
I had to revert to 1.20beta6 for now because starting from 1.20beta7 it resets every now and then and I have lots of failed prints because of that. I'm still running the latest 1.20beta9 WiFi firmware though.
-
Please can anyone else who is still getting WiFi disconnections even though the RSSI is good do the following:
1. Upgrade to the just-released DuetWiFiFirmware 1.20beta8 and DuetWiFiServer 1.20beta9…
I'll upgrade tomorrow morning (US Central time) and start testing.

OK - Firmware updated, WiFi debugging turned on. We'll see what happens. Here's the startup debug so far:

Ok - just finished a two hour print without disconnects. I am seeing many of the WiFi: p->ref == 1 messages. I also added an M122 diagnostic at the end.
Here's the full log so far. I'll keep the machine on.

The printer has been sitting idle since the last post (about 43 minutes).

I just had a disconnect.
-
I was not able to re-connect from DWC.
-
I am not able to ping the printer

Router is an ASUS RT-N66R running the Asus-Merlin firmware 380_68.4

Thanks for that. The p->ref==1 definitely indicates an error. I've spotted a patch that someone made to lwip 1.4 for the ESP8266, and that patch isn't in any of the official sources, so I'm beginning to suspect it. It's strange that I never see those messages.
The latest log entry you posted indicates the WiFi connection was lost but the auto reconnection done by the WiFi SDK succeeded. That's the first time I've seen evidence of that working.

I don't have any log data for you but I have some interesting other data.
I had been having numerous Ajax time outs and most of the time I couldn't reconnect but occasionally I could. I had a strong signal with RSSI values from -38 to -40. My network was made up of two Apple Airport Extreme (the latest version) access points. One as my router and the 2nd extending the network to my basement where my printer is. Sometimes the printer would connect to the access point two floors away instead of the one 6 feet from the printer. Also, since the Airport Extremes don't have a dedicated radio to extend the network the performance wasn't as good as it could be with some of the new tri-band routers.
Yesterday, I replaced the Airport Extremes with a 3 node Netgear Orbi setup. The Orbi remote closest to the printer is in the same location as that the 2nd Airport Express was. There is also an additional Orbi remote one floor up and the primary Orbi Router is two floors up from where the printer is. The connection has been rock solid with this setup for about 24 hours now. I've had a few disconnects related to the laptop going to sleep or such, but that is to be expected. I can always immediately reconnect when I need to. I have had no disconnects when I wouldn't expect them.
I'm also finding the my wireless performance better overall.
I think at least one other person has mentioned that they use an Apple router. It would be interesting to see if there is any correlation between what routers people use and the disconnects.
Of course, if this patch you just found fixes it, I guess it won't matter.

I have good WiFi connectivity, RSSI -43dBm, Broadcom chipset based router. Have upgraded to latest firmware and beta9 server, could do two small prints of 30 minutes without issue, this morning I could not reconnect. Unfortunately i accidentally turned off the pc i used for usb logging, will retry tonight.

I've had various problems with Duets and WiFi for a long time, and I'm also using an AirPort Extreme. It mostly works fine nowadays, but I'm still having problems from time to time. I recently updated to 1.20b, but it's too early to determine whether that has made a difference.
-
I've replaced my Apple router with Google WiFi today, and it still disconnects, so I don't think it is related to particular router model.

If it is router related I wouldn't necessarily expect it be limited to a single brand but it could be related to a particular WiFi chipset or chipset family. It's hard to say without a fair bit of data.

I haven't updated to the newer firmwares yet b/c this current setup has been working so well for me compared to really horrible results previously. BUT over the past few days I have started getting some disconnects an also getting locked out. It is still really good compared the past, with only probably 4-5 disconnects over the past 3 days. Here is my latest M122 immediately following a disconnect. I will upgrade the firmwares after this current print.

I've now been on my new WiFi network for 3 days and I have had no unexpected disconnects. I can reconnect immediately after any expected disconnects (laptop goes to sleep or I close my iPad) and the response is very quick.

Been following this thread for a while now.
What is the current consensus for stable WiFi ?
I have updated to the latest stable firmware and server releases. My printer is 300mm from the WiFi router and there are no other WiFi networks available and yet the network connection is currently dropping within seconds of starting the printer up.
I have managed to start one print in the last 2 days before the WiFi connection dropped and that ran to completion so it can only be an issue with the WiFi module.
Really beginning to wish I had paid the extra for an ethernet electronics board

I have managed to start one print in the last 2 days before the WiFi connection dropped and that ran to completion so it can only be an issue with the WiFi module.
Please work through https://duet3d.com/wiki/WiFi_disconnections_and_AJAX_timeout_errors first, in particular check the signal strength.
If the problem isn't signal strength, then the reports I have are that RepRapFirmware 1.20beta11 with DuetWiFiServer 1.20beta10 are more stable than the 1.19 versions in the stable release folder. So please try them. We have further work under way on DuetWiFiServer which we hope will resolve a remaining issue that some users experience.

Okay I have the recommended Beta's installed -
Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20beta11 (2017-11-28)
WiFi Server Version: 1.20b10
Web Interface Version: 1.19And I have MacPronterface, connected via a USB cable, monitoring the WiFi debugging messages - fingers crossed.

Thanks, let us know how it goes.
