I am worried that there is not really a benefit of doing that, just more noise and energy consumption.

    That was an amazing read. Thank you.

    What do you say is the use case for separating guest Wi-Fi with the more “private” stuff on your network?

    As far as I understand… Basically all communications, even inside a network, are encrypted… So I guess you do that to avoid someone trying to exploit some vulnerability?

      LOL, oh no.

      Even internet traffic isn’t encrypted by default.

      Sadly TCP/IP isn’t encrypted.

        If you don’t trust the person, why give them access to your WiFi in the first place?

          You can trust the person, without trusting their technical skills, such that they haven’t inadvertently installed malware on their own devices.

      Remember that once you give the password out, they likely have the password from now on. They will always have access until you change the password.

      No, a lot of local traffic is not encrypted, especially residential. No, residential probably doesn’t use much authentication or separation of privileges.

      I don’t want my guests to be able to access my home server or Omada controller for example, or spread malware (their phone may have malware without them even knowing). Also, I give the guest wifi to people other than friends, like contractors. Phone reception is horrible at my house so I give them the wifi so they can use wifi calling.

      if you know the wPA key, you know as much as the router. most connections now are ssl, but not all. and of course, you can’t go checking doors and windows if you’re locked out of the gated community.
