New test firmware 1.19+4 and DuetWiFiServer 1.19+1
-
If the WiFi module has disconnected from your router then it should write a message to USB saying so and giving progress information about the reconnection attempt. This was new in 1.19.2.
Doing a mesh bed calibration it disconnects mid way through. No output or messages on MacPronterface which was connected via serial at the time. I get no messages via serial at all unless I type a command to get a response.
On the MacPronterface if I do a M122 I get the following Wifi section:
Network state is running
WiFi module is connected to access point
WiFi firmware version 1.19.2
WiFi MAC address 5c:cf:7f:a4:a1:64
WiFi Vcc 3.13, reset reason Turned on by main processor
WiFi flash size 4194304, free heap 39840
WiFi IP address 192.168.2.54
WiFi signal strength -38dBm
Reconnections 0
HTTP sessions: 1 of 8
Socket states: 0 0 0 0 0 0 0 0
Responder states: HTTP(0) HTTP(0) HTTP(0) HTTP(0) FTP(0) Telnet(0)Trying to reconnect via browser that was open previously is " Error, Could not establish a connection to the Duet firmware! Please check your settings and try again" repeatedly, unable to reconnect.
Opening a new browser, to check Router (Asus AC3100) I see its connected and assigned an IP. Clicking on IP within router browser its unable to open a new window, it just times out.

That sounds like a different failure mode (connection stable but messages not getting through). Try enabling Webserver and Network debugging using M111, then see whether the failed attempts to open a session in a browser give rise to any debug messages in Pronterface.

heres whats the serial connection reports after after a disconnect :
HTTP connection accepted

HTTP req, command words { GET /rr_status HTTP/1.1 }, parameters { type=3 }
New conn on socket 0 for local port 80

According to that, the Duet appears to be behaving correctly. Can you get a Wireshark trace of the network traffic?
-
That is beyond my current level of network troubleshooting ability…
Once it disconnects, My web browser just repeatedly states it cannot connect, and the serial output is :

Sounds like the WiFi module has stopped responding. Sending M552 S-1 to reset it followed by M552 S1 to reconnect may get it working again, but that doesn't solve the problem.

Noticed that my PanelDue 7 flashes now every second or so. didnt do this before.. not sure whats causing it.
-
If you mean the backlight flashes on and off, or isn't a steady brightness, that's common if you try to power a 7" PanelDue from USB power only. A standard 500mA USB port can't provide enough current for the 7" display.

This helps occasionally.
After initial power on, once connected it seems to remain connected until I print. I have yet to have a print go beyond 15-20 min and stay connected since the update from 1.18I have a macro that disconnects wifi and reactivates so after it loses connection I can attempt to reacquire. I have maybe 50-50 success rate. Many times, doing this still I am unable to require web browser. The only sure fire way is to power completely off, unplug serial if connected, and power back up. Even if i do reacquire connection mid print using this method (macro not reboot) it disconnects again after a period of time.
My router shows ip assigned the entire time.
Safari, chrome, etc, browser has no change.

If you run M122 after a print, what MaxReps value does it give?
-
Tested during a print last night.
Disconnected 5 or 6 times I believe. Near the end of the print after I reconnected (by using M552 S-1, M552 S1) it stated MaxReps 5.
After print completed when I connect and do a M122 it says MaxReps 4. -
That value is nice and low, so it looks like excessive step pulse rate isn't a factor.
