Connected Devices - Recently on your network (What are these connections?)

When using the Eero app on my iPhone, under NUMBER OF DEVICES CURRENTLY ON NETWORK, under RECENTLY ON YOUR NETWORK, I am seeing many connections that are not devices in my house. The following is a list of connections: ACER TECHNOLOGIES CORP, ANNAPOLIS MICRO SYSTEMS, ANRITSU CORPORATION, CAYMAN SYSTEMS INC, DENSAN CO LTD, ICANN/IANA DEPARTMENT, IMC NETWORKS CORP, INFOTRON, METIER MANAGEMENT SYSTEMS, NET & SYS CO LTD, OLIVETTI NORTH AMERICA, STAR GATE TECHNOLOGIES, TIMEPLEX INC, UPNOD AB, WESTERN DIGITAL CORPORATION, XEROX CORPORATION and about 25 other connections with NO HOSTNAME but they have MAC addresses. Have they really been connected to my Eero network? Really concerned!!!

  • Hi ad313tg

    Thanks for reaching out and sorry for this issue you are experiencing. That sounds strange, so we should definitely take a look.

    I wouldn't be able to look into your network from here, but if you contact tech support, we'd be more than happy to dive into what you are currently seeing in the recent device list.

    Feel free to give us a call at 1-877-659-2347 or email us at support@eero.com. We'll be happy to provide more information with regards to what is potentially happening.

  • Made call to Support, gave information contained in my original question and my call was attached to another case that is similar. Hope to see a fix soon to eliminate these annoying "attempted" connections.

  • I have seen these too and what I did was look at the MAC Address of the device in the eero app then check devices in my home that I don't have connected. Once I matched the MAC address to the device then I added a Nickname in the eero app.

    Example, I had a LITEON Technologies device showing up driving me crazy. Every 5 minutes it would connect for a few seconds then disconnect. That device happened to be my Sony Blu-ray device which I turned off WiFi within the device. Similar incident with a Samsung Electro-Mechanics(Thailand) device showing as Recently on your network. By matching the MAC Address I found that device to be my Samsung 40" - 4K UHDTV. That one I kept WiFi on within the device.

  • Apparently there is something causing random MAC addresses to appear on the recent devices list.

    I don't have any Xerox, Rockwell, or Lexmark devices, but apparently these manufacturers have certain known MAC address that start with the same alphanumerics (OUI?), thus it looks like these devices were recently on my network if the random MAC address matches a manufacturer's known OUI.

    These devices never made a DHCP request and I'm told security is definitely not compromised, so that's a relief.
