WiFi Unreliable

[DessiVerse]

I do want to note that I have two pi's really close to the duet that never experiences any network issues. One is a Pi 3, one is a Pi 4. When I ran the Duet in SBC mode connectivity was fine, so it's likely an issue with the WiFi on the duet.

EDIT: I also do already have a WiFi repeater to ensure all my devices on the network run smoothly.

[DessiVerse]

Reading the M122 result signal strength is good at -39dBm so I'm not sure why I'm getting the problems I am. I was having upload speeds as slow as 3.5 KIB/s after posting the result.

[SIam]

@dessiverse your signal strength looks not bad (mine is worse and have no problem ). If your WLAN connection is slow again can you post again the result of M122. Perhaps is an Update to RRF 3.3 B3 a solution

[DessiVerse]

@siam how would I go about updating?

[SIam]

@dessiverse Here is the documentation https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware

The latest firmware you find here: https://forum.duet3d.com/topic/22878/software-package-3-3beta3-released

[DessiVerse]

@siam I updated the firmware and confirmed the update.
Console is still getting spammed with the below messages:

[SIam]

@dessiverse have you updated the DuetWiFiServer.bin ?

[DessiVerse]

@siam I’ve been trying to but it keeps saying the file doesn’t exist even though it’s in the sys directory.

[DessiVerse]

@siam

[jay_s_uk]

@dessiverse it needs to be in a folder called firmware with 3.3 rather than in the sys folder

[DessiVerse]

@jay_s_uk just got it installed. Doesn't appear to be improved though.

[SIam]

@dessiverse this looks good so far now the Wi-Fi has a software version and now test if this problem persists

[DessiVerse]

@SIam, I'm trying to upload a gcode to test the speed and it seems like it keeps slowing down. So the same issue I was having previously. I'd like to note I don't have this issue in SBC mode.

EDIT: It now slowed down to 1.8 KIB/s. Here is the current M122:

[jay_s_uk]

@dessiverse what sd card are you using? Brand and model?

[DessiVerse]

@jay_s_uk san disk edge, 8gb

[DessiVerse]

@jay_s_uk I just tried using my SanDisk Extreme Pro to see if it was an issue with that and it doesn't seem to be the case. I use that micro sd with my high fps camera so read and writes are never an issue.

[jay_s_uk]

@dessiverse the 8gb one appears to only be a class 4. A class 10 may be better. I suggest trying another as card if you have one.

[jay_s_uk]

@dessiverse what speeds were you seeing with the extreme?

[DessiVerse]

@jay_s_uk
same as before, and dropping since i took that screenshot. it's now down to 6 KIB/s.
