        I have a Linksys model EA7300 router for my home system. I have the guest network turned on. Occasionally I find listings for “unknown device” in the guest network. It lists the MAC and IP addresses but no manufacturer or device name. I’ve tried searches on both addresses but have not found much. I am not the sharpest knife in the drawer concerning networking. I just want to be sure I don’t have a problem. I live in a very rural area with the nearest neighbor or road 1/4 mile away, so I doubt someone is using wifi to hack. If it helps, the IP addresses for these two items are:

        192.168.3.xxx

        Looking that up shows they are reserved addresses, but I’m too ignorant to know what that means.

        TIA for your help

        Could be printers, phones, TVs etc.

        The printer and phones show up in the “My Network” section. These show up in “Guest”. It is password protected, but not a long password.

          Change the password to one that is more secure!
          If one of your devices is locked out, you will know to change it’s password too.

        Most routers assign a different IP range to guest networks.

        Another thing you can do is isolate your Guest Network from you normal network in the Router settings so the Guest cannot access any of your working PCs.

        I’ll try that. Thanks.

        The guest network is isolated from my network. I just wondered what would be trying to connect to it.

        Could be leftover connections when someone connected to it. Try flushing/refreshing connected devices in the router.

        One can do a lookup for the manufacturer of a device. The first 3 sections of a MAC identify the maker.

        Do a Search for [ mac address manufacturer code ]. The hit that I used is
        https://aruljohn.com/mac/3C2AF4 , but I’m sure that any of them will help.

        It’s possible that an unidentified device is from a Wi-Fi connection that was established once-upon-a-time and overlooked.

        In your Linksys Device List, if the background for the device is greyed, just ‘x’ it out and see if it reappears.

        I think a couple answers may have hit on it. My son and DIL were here last evening and both had phones connected to the guest network. I cleared the network map, but they didn’t disappear for a few minutes. When I looked later, they were gone. Logic tells me it shouldn’t be (can’t be?) a hacked connection with my distance to any houses or roads, but with all of the things going on today, it spooked me a little to see 2 unidentified devices connected. I’ll monitor it for now. Thanks again to all who responded.
