I have two units which had been working quite happily on my local home network. Neither unit will now talk to the network despite resetting them as per the normal reset button process. Invoking their IP addresses via my browser just results in ‘time out’ reports with no contact established.
One unit has a firm blue light against the power marking on the front and the other has a red light in the same position. In both cases the lights against the disks show firm blue.
Is there another way I can persuade them to communicate again?
