@Phaedrux same thing happens on access from phone

@phaedrux

also, if I simultaneously try to open DWC from my laptop, while I am on DWC from my PC, there is conflict, laptop cannot access to DWC.

let me know your thoughts

@phaedrux

No change at all. For example, I connected to dwc via my laptop. I shut the laptop down, DUET stays on, then I try to connect to DWC via my PC.
This happens every time I shut my explorer window down. Now, I used my laptop browser, shut it down, then re-opened it from my PC. There is a conflict somehow and I don't know if it is Duet hardware or router wifi related

Connection error.
Should I just change the connection type of duet to broadcast?? I mean, no need to connect to router, be independent network.

Would that act as a solution??

@phaedrux

I installed the newest firmware as you suggested.
The motherboard performed a restart upon finish.

I cannot connect to DWC after the restart, although motherboard is connected to wifi ( blue light is on, NOT flashing ).

Seems that this issue is not over yet. Don't know where to start from, router or duet??

@phaedrux I am using duet to connect to wifi modem. I experience the abovementioned issues.

This is my 122 command

@tecno so, this is the solution???

Hello,

I have a duet wifi 2, configured on Wifi host mode.

Whenever I close my Explorer window, or my pc goes to sleep mode, I cannot access to DWC. So, when I start printing and my pc goes to sleep mode some hours later, I am not able to do anything during the print, besides wait to end.

On my previous, duet I did not have this issue. Where do I start??
Router configuration or config.g ???

PS, I did change m586 telnet and ftp command from disabled to enabled, but it didnt make any difference

I have plugged those two fans on the allways ON ports.
So, after reading your comments, I assume that they cannot be thermostatically controlled???
