I want to make comments for the devices in the Wi-Fi registration table and I found that the only way is via CLI. The problem is that I don’t get how to save the text. Below in the window I see the shortcuts needed, but they do not seem to work in any combination with CTRL, ALT or simply entering “C” “o”. Screenshot attached.
/interface/wifi/registration-table> edit
number: 1
value-name: comment

Well, it looks like “C-o” means Ctrl+o, but it doesn’t save… While “C-u” works as intended.
I had the same problem, and realised that my telnet client was binding CTRL-O to “flushoutput”. Turning that off fixed the problem.
Steps:
- Press CTRL-] to get to the telnet prompt
- Type “unset flushoutput”
- Try again

Hi, are you sure?
As MikroTik says comments are not supported for Wireless Registration table entries (forum – Comment feature on Registration list, documentation – Wireless), and only shown ‘forwarded’ from the neighbouring Access Control List section (if specified there).
Even though Terminal (IMHO very inappropriately) does show the edit and even comment commands for an RT entry and enters the editing mode for it.
Or RouterOS does support RT comments for newer devices (such as using wifi-qcom package)? documentation – WiFi simply doesn’t have details for the RT.
