WiFi Unreliable

Did you try sending M552 S2 after that? That should enable the module in AP mode.
-
@phaedrux I'm trying this now, but the second I send
M589the duet goes offline and is unreachable. I'll have to try via USB. -
@dessiverse This may not be your problem. On a previous firmware for my ASUS RT-AX56U, I had to reboot the router once in a while to get back my wifi connections to my printers. Duet 3 6HC with a PI 4 and Mini 5+.
-
@stephen6309 That's, concerning.
-
@phaedrux Hello, finally got to test it, and using the Duet in AP mode there were 0 speed issues. Any ideas as to the causality of the original problem?
-
So AP mode the speed is great, but when connecting through your router the speed is poor?
That would tell me there might be something going on with your router settings maybe. What kind of wifi router are you using?
-
@phaedrux It's the Xfinity Modem / Router combo. I don't think it's an issue with the router only because no devices on my network have any speed issues. Even 2.4GHz devices. I have a Pi 3 that runs on 2.4GHz mode that I was using with SBC and it had no issues with speed.
EDIT: Is there any diagnosing things I can do to confirm if that is the case somehow?
-
I'm not saying the router has a problem in and of itself, other than it might not be playing nicely with the duet wifi module. Though any time there have been issues like this it's been with ISP provided gear. Off the shelf stuff usually works without issue.
You mentioned a wifi repeater as well. What is it and how is it configured? Is the Duet using the repeater or direct to the router?
-
@phaedrux The repeater is like a pod Xfinity offers? I'm not really sure how it is configured. The Duet is using the repeater as well
-
@phaedrux Question, is it possible to view the dashboard via OctoPrint or another way? I'm trying to see if I can bridge the connection to mitigate the WiFi issue

Maybe try tracert (win) or traceroute (linux) to the Duet from other machines may give some clues. If there are repeaters involved the results may (or not
) point to some differences.
Also - is the repeater a bridge (same ip subnet on either side of the repeater) or is there a different subnet to the router? If the latter - what happens when everything is on the router side with the repeater turned off (just for luck
) ? -
@stuartofmt I tried SSHing into the duet but it wasn't letting me connect? It kept saying connection refused so I couldn't diagnose most things at its end
-
@dessiverse, here is how you can test whether it is the WiFi or the SD card writing that is slowing down the upload speed in standalone mode:
-
To test the upload speed, rename a large GCode file (or any other file) to a name ending in ".dummy", then try to upload it on the Jobs page. You will need to set the file filter to "all files" to allow you to select that file. This will upload the file without writing it to SD card.
-
To test the SD card write speed, send M122 P104.

@dc42 It's not the SD Card because when using the duet in AP mode the upload speed was perfectly fine. So that loops it back to, how do I narrow down what's causing the WiFi on the duet to be slow when it isn't a problem with other devices on the network?

I'm not aware that Duet supports SSH so that error makes sense
What I had in mind was from some other machine (like the one that you are trying to upload from) to the Duet. e.g. tracert Ip-address-of-duet.
What you want to see is a direct connection - something like this (from my win machine to my Duet (at 192.168.1.150:C:\Users\stuar>tracert 192.168.86.235 Tracing route to 192.168.86.235 over a maximum of 30 hops 1 164 ms 7 ms 9 ms 192.168.1.150 Trace complete.Thinking about this - better commands may be pathping (win) or tracepath (linux). They basically combine tracert and ping in one command. For example - my equivalent of the above is:
C:\Users\stuar>pathping 192.168.86.235 Tracing route to 192.168.1.150 over a maximum of 30 hops 0 Stuart [192.168.1.5] 1 192.168.1.150 Computing statistics for 25 seconds... Source to Here This Node/Link Hop RTT Lost/Sent = Pct Lost/Sent = Pct Address 0 Stuart [192.168.1.5] 0/ 100 = 0% | 1 9ms 0/ 100 = 0% 0/ 100 = 0% 192.168.1.150 Trace complete.and throw in the results of ping for good measure.
Basically just trying to rule out any strange network routing.

Don't like the timeouts on a LAN ... What happens when you ping the router ? Do you see time out's occurring there ?

Do you have access to any xfinity router config pages?
Can you contact the ISP for some support?
Do you have a separate router you can setup as an access point to test with?
