Yes you are right, I have M587 in config.g

; Network
M550 PMy_Printer ; Set machine name
M552 S1 ; Enable network
M587 S"########" P"######" ; Configure access point. You can delete this line once connected
M586 P0 S1 ; Enable HTTP
M586 P1 S0 ; Disable FTP
M586 P2 S1 ; Enable Telnet

Today I had another round of issue with the wifi connectivity. As suggested, here are the M122 dumps

I had upgraded to Firmware 1.21, however not sure if the wifi issues started prior to the upgrade or after....

=========::details from web interface:===========
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 1.21 (2018-03-21)
WiFi Server Version: 1.21
Web Interface Version: 1.21

==========================

Few other points: once the wifi is connected I do not have any issues with disconnections / timeouts. the web interface responds for whole duration of print, even after 12+ hours

Is there any reason for the wifi led on the board to glow solid blue directly before blinking a few times, after powering on

undefined

I am having issues with my duet board connecting to wifi router. Over past several day I have tried several things but the issue keeps recurring to the points that I am frustrated with the board.

Tried to recycle power, use on-board reset button, set specific channels on the router, moving the router just next to the board, Telnet to the board and update the wifi firmware

Few of things that I noticed:

after flashing the wifi the board most likely connects.
In between the power cycles the wifi connects when the on-board wifi LED blinks and then turns solid. Mostly, the blue wifi led glows directly without blinking and in such cases the board is never connected to the router.

Pls advice.
