    2 users - 1 wireless connection
    « on: December 29, 2018, 12:50:54 PM »
    Hello

    If 2 users in the same building (home not office) share the same wireless connection (same provider, same security/wi-fi key), can either of those users see the online activity of the other one?

    Thanks

    The simple answer is NO.

    The long answer depends on what security measures are in place.  Normally only input and output for a named used only goes to that user. In fact, you have to work at it to see what others are doing, unless have full administrative authority.

    Otherwise, one user One can peek in on others by a deliberate violation of security.

    Is this for a business?  Is this to monitor you children's activity?

    It's not particularly easy but there's definitely tricks that someone could do in order to intercept traffic from other users. Higher end enterprise systems tend to support client isolation features to avoid this but they aren't always enabled and generally aren't supposed by consumer networking equipment.

    Normally only input and output for a named used only goes to that user.
    The key word here is "normally" - if someone malicious wants to intercept traffic, it's still possible for them to do so.
