Wifi/DWC Disconnecting with RRF3.5.2 on Duet2 Wifi Hardware
-
@droftarts I didn't read all of the original posts, but it sounds like what I've been seeing. WiFi suddenly disconnects unexpectedly. It usually reconnects about 15 seconds later, but I've been dumped out of whatever macro folder I was looking at, and if I was editing, I'm dumped out of the editor. Everything functions fine until the next time it happens. M122 is below. I have replaced the SD card recently and this problem predates it (it's been happening for months). I also occasionally get WiFi failures at power on, but not frequently. Cycling the power fixes that.
When this happens I sometimes wish I had a wired ethernet connection to fall back on (or just use most of the time, but still have WiFi available). I've been considering replacing the Duet2 WiFi with a pair of Duet3 Minis, and I was wondering if one can have WiFi and the other ethernet and thus give me the choice.

So at this point, I guess I will stay on RRF3.4.6 and WF1.27 for now.

Hi, I've been looking into some improvements to the WiFi firmware in terms of connection stability. Below is my initial build with those changes. If possible, please do try it out and let me know if you still encounter issues.
Note: After firmware update, please confirm M122 outputs wifi firmware version as 2.1.1beta1.
-
@rechrtb I'll try it! Just installed RRF 3.6 alpha 2, which seems to work fine.
-
@rechrtb I have it installed. I'll let you know if I have any disconnects.
-
@DonStauffer Thank you!
-
@DonStauffer By the way, is the disconnect something you can sort of 'induce'? Because, if you can, please do try it on this new firmware.
-
@rechrtb I haven't seen any way to make it happen. It may be my imagination, but I think it happens more in the afternoons than mornings, if that makes any sense.
No trouble since last night's update to RFF & WiFi.
-
@DonStauffer @trd87t Hi, I just wanted to ask if you encountered issues with the beta firmware build so far...
-
@rechrtb The WiFi still disconnects unpredictably. Alpha firmware and beta WiFi didn't make it better or worse. I don't see any pattern except it seems more in the afternoon. I was assuming it was an interference problem, although other houses are at least 100 feet away here, and the Duet is about 10 feet from my router. But with increasing bandwidth use for WiFi I figured interference.
The biggest problem is if I'm editing a macro or something it drops me out and unsaved changes are lost. If I had the ethernet board I'd just have gone with a wired connection.
-
@DonStauffer I see. Sorry to hear you're still encountering issues. When the issue occurs, is DWC open in multiple tabs (same or different device). Or perhaps a transfer is going on? Also, this doesn't happen on 1.27x wifi firmware?
-
@rechrtb Nothing is necessarily happening, and no, not multiple tabs. Sometimes I even go out of the room briefly and come back and I see in the console log it disconnected then reconnected. Sometimes I see it happen. Usually it's out for anywhere from 20 seconds to a minute or so.
I don't remember the firmware version for sure but I'm pretty sure I was on the latest released version, and now 2.1.1beta1.
-
console log it disconnected then reconnected.
Oh, do you have what that log says? Also, do you happen to have a mesh/multi-AP setup, and the router you mentioned just happened to be the closest one?
-
@rechrtb said in Wifi/DWC Disconnecting with RRF3.5.2 on Duet2 Wifi Hardware:
mesh/multi-AP
Only one router in my house. I think the log entry just said it lost connection. Next time it happens I'll copy the log entry and post it here.
-
@DonStauffer Thank you! I initially thought that it's only the DWC reloading, but in your case the module itself seems to be disconnecting from the access point).
In the meantime, there I have another beta build. This also contain more fixes compared to the last one. If you're still inclined to try it out, it would be highly appreciated!
-
@rechrtb I'll install and test it and report back. Thanks!
-
@DonStauffer Have you had the chance to take the new beta for a spin?
Also, do you have other protocols enabled? Ftp, Mqtt, etc?(Sorry, I just remembered I can look at the M122 output to have the answer to this question) -
@rechrtb Sorry for the delay. COVID-19. I'll try to figure this out today.
-
@DonStauffer Oh no, no rush! Hope you get well soon.
-
@rechrtb It hasn't been too horrible. Just horrible enough...
Here's the console log, RRF 3.6.0 alpha 4 with the WiFi firmware you posted here; the " Incompatible software" error message is just from having the alpha RFF:
