Router and laptop periodically showing as Cimsys device

Hi there -- at various times my router has appeared in the device list as a Cimsys device with the same IP address (10.0.0.1) but the MAC address 00:11:22:AB:CD:EE. Most recently my router was displaying my laptop IP and the same Cimsys MAC address. Is this something I should be concerned about? Thanks in advance for your insight!

    Can you give us a little background on how your network is setup? For example, the type of equipment your using, aka router model, if you have any range extenders etc...

    Hi @CZPatterson as your MAC address is the same in the examples you quote it is likely that Fing is misidentifying the device (the hardware mac address doesn’t change). The next time it happens type the IP Address (10.0.0.1)in a web browser and see if you actually access your router or a different device this should give you a pretty good idea what’s happening & if it proves to be misidentification you can edit & correct the name for future reference.
    The other alternative is to block the device and see what you lose access to, I would only recommend this approach as a last resort as, if it’s your router, you may need to reset it to regain access.
    Back up everything before you start.
    As always, check your AV software is current before doing your investigation.

    GOOD LUCK.

    Thank you both, and hi, Daphnee! I have the Technicolor CGM4140 and three Shaw WIFI pod range extenders.

    I should clarify -- the MAC address is the same in both of the images I posted but it is not the MAC address of the router.

    I'll take your advice to check the admin console when it happens next and see if anything jumps out. Appreciate the input.

    Here is an example of what Fing desktop displays on my network re: above. The Devices report shows the correct MAC address for my router (with an incorrect one and the OS of the device I'm accessing it from directly above), but the Home network report shows the incorrect one as active -- at the same time. 

    I'm curious -- Should I take Fing results at face value or are they just “best guess” and kind of just for fun? They are always so all over the place that I don’t trust the information at all, but it's not a particularly expensive tool and maybe I'm expecting too much from it. Any thoughts on this?

    I have the same router as the poster above and just noticed this as well. The technicolor. Running on Cox. This router still has xfinity coding all over it and I think it’s a bug of some kind
