Pete Whittaker Posted December 8, 2019 CID Share Posted December 8, 2019 Hello! 'They' say for an accurate test to connect the ethernet cable to the modem, but when I do that I lose connection altogether, with or without Wifi on. Strange.

CA3LE Posted December 8, 2019 CID Share Posted December 8, 2019 You may have to unplug your modem for like 10 seconds and plug it back in to get it to assign to the MAC address of the newly connected device. Once it pairs to the new device you'll have to do it again if you want to switch it back or try a different directly connected device.

nanobot Posted December 15, 2019 CID Share Posted December 15, 2019 Are you connecting directly to your modem / router (whatever they call these silly boxes these days)? If not, are you connecting to a different switch? How long do you wait when you plug in? If it's less than 30 seconds, give it a good minute or two after plugging in to see if the situation changes (whatever the device is, it's entirely possible it's running Spanning Tree which typically takes 30 seconds to validate that you didn't just create a switch loop in your network). If you're waiting longer than that, the suggestion by @CA3LE is the next place I'd look. After that, perhaps test the cable and device port you are using (I see cables go bad every day).
