i have bridge with B5-lite, everything working good, but i need temporary disable connectivity. optimal for me would be somehow disable ethernet port on remote client, but i have no option in interface to do so. other option - block client from connecting temporarily (i unable to just power-off it, as both installed remotely). change password is also not a good option as i do not know it, and i will be unable to update it on remote location.
any suggestions how i can block data flow but still have connectivity to AP/client (shutdown radio on AP, or ethernet port on client)?
