What switch do you have? Is it a managed switch?
unmanaged
With the DSP plugged in, can you go to http://192.168.0.60? What comes up?
just factory reseted them
Does the DSP perform normally when on?
yes, when router is up it just get it's own IP and work like nothing happened.
But I have a problem, I connect to DSP, go to 192.168.0.60, login with Admin and PIN from sticker, and all I have is some information about device but no option to upload firmware.
