I tried covering the WIFI adapter with Aluminium foil but it was too sensitive for me and I only managed to get from -61db to -79db. So had to switch off router. to change access point. (I think part of problem might have been having too many access points with the same SSID - I am no longer doing that).
ps I went from a v old Duet - second production batch to this and it has been great - I actually just get on with printing.

Another in the heffalump trap!

I had loaded the Web Interface first. Fix was like procedure 1.

• Power down and extracted the uSD card

• Copy and rename the latest set of files

• Reinserted card and powered on

• Send the command on the web interface M997 S0 this upgraded the firmware

• Then upgraded the WIFI server using the web server

Looking better - so back to rebuild the Ormerod 1. Such quiet motors - lovely.,
