Hello,

my 4 unit system has been working great for well over a year, with only the odd reset required ( TP - Link AV1200 Gigabit (TL-PA8030P))

Over the last 2 days the system has been extremely erratic.

I updated the TP PLC Utility Software and then started firmware updates on the devices.

This morning the Utility is showing a 5th 'Unknown Device' - DEVICE-E035 - with no bandwidth details

I changed the default Network Name under security.

Now it shows as connecting at 56 Mbps and it's not device I know of in my house!

After about 10 mins it's disappeared again.

How do I find out what this device is?

Is is safe to just delete it if it re-appears?

Is this a neighbours device that's on the same electrical circuitry as my house?
