@dc42 got it thank you

@jay_s_uk Hey Hey! The USB hub solved it! A new BOSSA COM port open in YAT.
Continue in YAT as per usual set up for a new wireless network?

Hello all,

I have a Duet 2 WiFi V1.04 (no erase button), unknown firmware on an Ender 3 [V1] Pro.
It ran great until I moved and tried to connect to a new wireless network.

I followed:
https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond#Section_Check_the_voltage_indication_LEDs

I tried to connect via YAT under USB power only. No luck.
I checked Device Manager on two Windows laptops and the board did not appear anywhere
I found/followed the above link
The lights on board were: 5v, 3.3v, & red light b/t rest button and USB. The DIAG light lit up ~0.5sec then remained off
I jumpered the erase pins (no erase button), applied USB power (few sec, per the link) then removed USB power & jumper
I applied USB power lights are same, plus DIAG light now remains on
USB inserted I checked Device Manager and got "device descriptor request failed" (code 43)
Board still unresponsive, I even tried with/out SD card inserted. I bought through Filastruder two years ago so I am likely outside my warranty.

How can I save her?
Thanks! *smiles in noob

Thanks, I will try that as soon as I get back home. I appreciate the help!

Hi, thanks for letting me be part of this community.
Problem:
HTTP request has timed out, occurs only on my Macbook. Works fine from smartphones and tablets. I'm not sure how to proceed and I would appreciate any help, thanks!

@dc42 I am not using a filament monitor of any kind. But I suspect that I have improperly wired the board.

I can get all 3 axes to home properly.
Nozzle and bed get to proper temp.

Any print stops within 2 min and "Extruder 0 reports too little movement"

New install on Ender 3, obvious under extrusion on the bed. Tried keeping extrusion clip very loose on the extruder thinking it was a failure to feed filament.

If it's a firmware tuning issue then I'm not sure where to start?
