Changing MAC addresses?

[DIY3dguy]

I have a DuetWifi and have set a reserved IP address in my DHCP client settings to keep the web interface as a pinned tab in my browser.

Half of the time when I reset the duet, it reconnects to my router with a difference MAC address and takes the next available client address instead of associating with the permanent, reserved IP.

I figure that's likely an error in the WiFi module? If not, is there a setting for this that I am missing somewhere?

Thanks in advance

That does sound like a problem with the WiFi module. It's possible in theory to set the Mac address in firmware, but we don't use that facility because each WiFi module is supposed to have a unique default address.
