What is RTT? 21 December 2012, 02:04

Hi everyone
No doubt a dumb question ... but what does the RTT stand for?
Thanks!

I really like the WiFi Guard app and would like to know every detail it's telling me.

RTT is Round-Trip Time, also known as ping time. In simple words, it shows how long it's taken to receive a response from a computer or device.

In more detail, RTT is the length of time it takes for a data packet to be sent plus the length of time it takes for a response to that packet to be received.

No, it means the host did not respond to PING and the round trip time could not be determined, however it did respond to an ARP request.
Some devices do not respond to pings and can only be detected by their ARP response. In this case no round-trip time is displayed.

The info above is helpful, but I am on someone else's home network (Internet access comes with the rent) and checking the responses on WifiGuard.
I see a device that has a MAC address, but RTT is ---. My question is, what kind of devices might one find on a home network that do not respond to pings?

It could be, for example, a PC that has a firewall configured to filter incoming pings (in the attempt to make this PC undetectable). In our office network here, quite a few devices do not respond to pings:

Another question about RTT meaning: it it correct that the lower is the ms in the RTT the faster is the connection?

Generally speaking, yes. That is correct.
