Issues with Wifi - Duet 2 Wifi 1.04c

[petriheino]

Hi,

I've been experiencing several issues with Duet Wifi in different conditions.
Usually those may be related to router connected to but there is others also. Always with latest stable DWC and RRF versions (now 3.3).

Wifi Access point keeps collapsing on uploading large files via DWC
With laptop, connected in same room, filesize 20-100MB.

Macro for making access point:

M552 S0 ; Turn network to idle
M589 S"DuetSSID" P"password" I192.168.0.1 C1 ;Configure access point
M500 ; Save settings

In config.g

M552 S2 ; Enable access point

upload may work on second or third attempt.

DWC file upload collapses router
With some 4G/5G routers (Huawei and others) DWC upload may result in completely freezing LAN (or making a very high network-wide latency to all users)

Very slow upload speeds on special routers
With some Cisco and others mesh-type routers DWC upload speed may be only 10kbp/s or not able to connect to DWC.

What would be recommended method to start troubleshooting these types of errors? If enabling Wifi debugging features, which data to look for?
