Hello
Again thanx for your help!

I am not sure what I did differently but after uploading 2.05 firmware and dwc board start working. Now works every other FW too.

Strange, but I am happy

Thanx for answer!
I am definitely doing something wrong.
Now page says
"Your Duet rejected the HTTP request: page not found"

I unzipped file to www folder on the card - and the browser says that
Tried to type M997 S1 - same answer from browser
I unzipped all the .gz files - same
tha again M997 S1 - same

before this i tried to return to other versions of firmware and always did M997 S1 and M997 S0.

never got connected to board
im startin to think that board is bad

Now, after countless reload .

1. Button in the left top corner changed color to green, but next to red buttonon the left si Gray rectangle with text Disconnected.
2. Menu items are clickable, but Configuration file tab says loading.
3. In the middle next to My Duet is yellow rectangle with "some axes are not homed"

After next page reload same unresponsive UI

Hello, I just upgraded firmware to latest 3.11 and every browser returns disconnected, inresponsive UI.

YAT says:
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-19b2

WiFi module is connected to access point and have IP address

Installation process:
I copied files from Duet2and3Firmware-3.1.1.zip to sys on SD card from my computer.
Reinserted SD card to board.
Connect with YAT.
Connect to wifi M552 S1
Run M997 S0
Reset

Really strange thing is that twice it randomly was get conncted

Any suggestions?
