Clients still reconnecting after WPA2 key change?

[Milothicus]

we're running an ASUS RT-AC68U with the most recent firmware updated through the web portal.

we've had a couple of people leave the company recently, so i've changed the encryption key to prevent reconnection.

it seems like any client that has connected in the past still connects without requiring the new password.

is there a way to force all clients to input the new password to keep the former employees out?

That shouldn't be possible. Are you sure you have changed the password on both bands (2.4GHz and 5GHz) and any guest networks?

bingo. forgot to change the password on both bands. clearly it's monday morning.
