I lost my netgear modem come router when moving my apartment. Does it a concern in terms of security? Does the device might store any of my devices like laoptop, phone, tablets or smart devices IP or Mac address? If so, what should I do to protect myself from all vulnerabilities? Also please let me know If I can disable the lost device in anyway. Thanks in advance for any ideas here.

       Model?  "modem" or modem+router?

       I wouldn't expect a modem to remember anything significant. A
    modem+router could remember a few (more) things, but I don't know what
    anyone could do with some old IP or MAC address.  Choose different
    wireless SSIDs and passwords for your replacement device(s), if any.

       I doubt it.  Although someone else might have a hard time using it if
    your old ISP thinks that it's still yours.


       Computers (including phones, tablets, and the like) have signifcant
    on-board storage (hard disks, solid-state disks, flash EEPROM, ...).
    It's a much smaller problem for a router, and still smaller for a modem.
