I understand for "kicking" a momentary (temporary) disconnection of a specific associated wireless client.

It is not the same as "banning", that includes some sort of permanent black-listing of such client.

How could this kicking of a specific wireless associated client be obtained by using command-line methods?

  • ban, and release the ban (if you happen to have a script to ban)? Because my understanding is - even if you kick the client - the client will simply attempt to rejoin to the wireless. If you ban for 1 minute or so, Windows client usually "give up" and make it into a manual connection - unless you don't want that to happen? – Darius Jan 17 '18 at 1:47
  • Indeed, @Darius : ban and quickly release the ban could be a valid method. If there is no valid answer here, trying at StackOverflow could be a good idea. Thanks you. – Sopalajo de Arrierez Jan 17 '18 at 2:06

UPDATE: simplifying informations thanks to comments from @pim

The best method to retrieve association informations for eg on card wlan1 should be the command iwinfo wlan1 assoclist that can be installed with opkg install iwinfo, or with modern drivers: iw dev wlan1 station dump . Anyway the "kick" method here (disassociate) is supported only if the hardware is supported with hostapd (Provided by default by the combo package wpad-mini on OpenWRT)

The default wpad-mini package does provide the disassociate command but not the all_sta. So get the list of associated clients on card wlan1 with iwinfo wlan1 assoclist, select a MAC address and then "kick" it with (for example):

hostapd_cli disassociate -i wlan1 01:23:45:67:89:AB

Considering a client usually tries to reconnect when disconnected, this might just disconnect it for about 10s.

  • Excuse me, but what do you mean for "tested with actual Wireless"? Some Linux distro acting as access point, maybe? – Sopalajo de Arrierez Jan 17 '18 at 3:08
  • I just tested it on openwrt (lede 17.01.4). The all_sta command is not working, but the disassociate is working. This is probably because the default install use wpad-mini and not the full-featured hostapd package. – pim Feb 21 '18 at 7:12
  • @pim Ok. So it's a bit more difficult to know what to disassociate. How do you do it? logs ? – A.B Feb 21 '18 at 7:34
  • To get a list of connected clients : iwinfo wlan1 assoclist (iwinfo must be installed first (opkg install iwinfo)) or iw dev wlan1 station dump. And don't forget to use the same interface for the disassociate command, example : hostapd_cli disassociate -i wlan1 01:23:45:67:89:AB – pim Feb 21 '18 at 8:41
