connections to my network

I just had to redo all connections to my network due to someone else logging into it. I know I only have 8 devices on now but my list shows 9. One of them listed is from Arcadyan Technology Corporation. Does anyone know what this is?

Thanks in advanced for any help I can get.

They make all kinds of networking equipment like wifi extenders, routers, adapters, networking chipsets etc.  It could be anything you have in the house that uses their chips, even one of your computers adapters, wifi extender, bridges, blu-ray, streaming device, thermostat.

You can check and see if the indicated MAC address matches something you actually own.

I checked the MAC address and it came back as Arcadyan Technology Corp. Which is a company that makes routers. My cable modem/router is Arris. I went through all that I own and have connected and this seems to be extra item and in the devices it's listed as computer. Can I just block or delete it?
