Hello, I'm Y.ssk. An edit that you recently made to 802.11 Frame Types seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks!  Y.  ssk  08:30, 23 August 2021 (UTC)
