Duet 2 WIFI network issues
-
Hello! I have really been struggling with the Duet 2 WIFI connectivity for a long time and I would like to fix it once and for all, even if that means buying a new board or something. The WIFI barely works and seems to be getting worse over time, now it won't even stay connected for more than a minute or two. This is with the board just on the bench in open air powered by USB. It is really frustrating as it makes the printer pretty hard to use. The WIFI signal is very low but it is not blocked by anything. Below this is the M122 info. Any help would be appreciated! I'm at the point where I am ready to just buy some other board, but love the Duet interface when it works. Thanks for any help!
p.s the whole M122 is not here because this post was getting flagged as spam, maybe too long?

Hi,
I've the same issue with my duet 2 wifi. The connection is unstablel and no working more than somes minutes long. I try to fix it as well. what type of antenna do you use ? -
@protoplant said in Duet 2 WIFI network issues:
WiFi signal strength -80dBm
this is too low. you want a value of -60 or less
your wifi firmware version is also super old (you're on 1.21 and the current is 1.27)
What main firmware version are you running?Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
@rodrigue-richalland Hello, it is just the stock antenna (on-board) that came with the duet 2 wifi
-
@jay_s_uk Thanks for the reply. Yeah -80 is super low but I'm not sure how to make it better, it is in the same location as my other devices that can stream video etc on the same network. It is also not in an enclosure or anything, I have not been able to upload a file for a long time.

@protoplant maybe changing the orientation of the baord might help. But really as @paolozampini1973 suggested, a repeater may be best. The esp8266 internal antenna isn't fantastic.
I would also suggest making the leap to RRF3 as a number of improvements have been made -
@jay_s_uk Thanks. I suppose a repeater could do something? Although it is only a few feet from the wireless router. Maybe the best solution is to just replace the board? Is there a way to add an antenna?
Also, will RRF3 run on this? I just sort of assumed that was only for Duet 3 boards...

@protoplant
I've ad a 2 meter antenna on my duet 2 wifi and the result is same that what you explain here. I will do somes others tests tomorrow morning. If i find something,
I'll let you know. -

the router How many meters is and from the Router there are walls or is it free to reach the board?
-
@paolozampini1973 Hello, thanks for the reply. The router is about 5m from the board, there are no walls or floors between.

@protoplant you can run RRF3 fine.
If you have the equipment you can always swap to an ESP-07, which has a connector for an external antenna -
WiFi signal strength -80dBm with the router in the same room makes me think there is an issue with the module/antenna, but updating the firmware would be something to try at least.
If you still have access to DWC. Upload these 4 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.3/Duet2and3Firmware-3.4.3.zipThat will get your firmware and DWC up to date.
You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.xFor your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/StartBackup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.
These documents will come in handy during the conversion.

@phaedrux Hey thank you so much for all the detailed information. I was able to get it running on 3.4.3 (not printing yet...) and the wifi signal seemed about the same. I've got a few of these so went ahead and added an antenna, that got me up to -49db. This will be nice to get it out of the housing when it goes back in. Hopefully this gets me there, and it doesn't take too long to get my config file back up and running... Thank you for the help!!
-
@protoplant Just a quick correction, the increase in connectivity was not as much (-80 to -49) as I first thought, it is very sensitive to position and with the board in exactly the same place as the other it is more like -80 to -75, which isn't a whole lot better. I have 2 boards so I can compare them in the same place. This will be a nice mod for in the case however, as it is a thick aluminum casting, we will see how that works out. I guess this module is just fairly sensitive to position/location of the router, I will see if I can get a better signal to it.
-
@protoplant you could swap out the ESP WiFi module for a version with external aerial. Search the forum for examples. Duet3D also sell Duets with external aerials!

@protoplant
Did you find a solution to fix your netwotk issue ?
I still working right here.
