    WiFi 802.11 overhead

    A point of curiosity about Wifi 802.11 ac overhead. I have a wired Ethernet Internet link which tests at around 500 megs download. Using a Wifi 802.11 connection, the download speed tests around 285 megs download. Am I correct in assuming the difference in download speeds is typical of WiFi overhead?

    There is no 'typical' ac Wireless overhead. Hardware varies as to the number of channels used and some other factors.

    You also have to consider the hardware each end of the wireless link, it will run at the slowest of the two bits of hardware. There are also more errors in using Wireless than wired so data has to be resent.

    Too many variables as Helmut noted. But the best one I got was 550/867 Mbps throughput

    There are all kinds of things that can limit the speed of a WIFi connection. Many of these things cause errors which force the data to be resent. A chain is only as strong as the weakest link. Speed will be limited to the capabilities of the slowest link in the signal path. Nominal speed is obtainable only with quality equipment under ideal conditions which are typically not present.
