Really Invisible WiFi (not just hidden)

I want my WiFi to be invisible to anyone, and I don't mean hidden. I know about the hidden SSID method, but in this method the network is visible like "hidden network". I would like to create a really hidden network, visible only to me in someway. Is it possible?

Hi WiFi network as it names says is wireless, you can't hide it.

There is few options you can do like disable beacon frame broadcast.

Than you won't be able to discovery network SSID. But packets will be still sent and simple WiFi scan would find your network SSID.

You can decrease TX/RC power to make it range shorter just to cover chosen area.

Modification of frequency spectrum that WiFi client and AP is working on different than assigned frequencies (2.4, 5) but it would be more likely illegal to use different range. It as well not hiding your network but moving it to different frequency and with proper tools you would be able to see packets flowing.

  • What you're trying to accomplish is not really feasible. As Wi-Fi uses radio waves, they will propagate to the environment. Really, the only way to prevent others from seeing your Wi-Fi is an RF-insulated room (implemented using a Faraday cage -- you need to take into account the wavelength of Wi-Fi signals if using a net instead of using solid metal). Such rooms are very common in companies that do radio wave related work. Oh, and your mobile phone will not work in such a room.

    May I suggest a wired network instead? You can hide your wired network extremely well: in theory, there may be some emissions from twisted pair cables, but in practice nobody with an ordinary computer will see that you have a wired network. If your enemy is an intelligence agency, then you should consider reading the Wikipedia article on TEMPEST.

  • I guess there are a couple of ways to go about this.

    1.Buy some Japaneese equipment and use channel 14 at low power - you

    may bleed onto ch. 11 a little bit, but they will have to be very

    close. -- not legal of course

    Get some 4.8 GHz Public Safety WiFi equipment. -- not legal of course

    Go find some old FHSS adapters. -- 1 Mb/s isn't that bad.

    Use Bluetooth. Hardly anyone looks for that.

    Totally re-write the wifi-driver software to change the checksum method and everyone else will drop your packets.
