Hi
I am using MikroTik router OS hotspot feature to connect clients. I also have users who connect on VLAns.
Basically to disconnect any hotspot user, I simply disable his/her username.
To disconnect VLAN users, I disable their IPs.
Now the tricky part is that on one VLAN, I have five users sharing one address using o D-Link router.
Is there a way I can disconnect any of these users without disabling the five?
Use a switch instead of a router or a rb750 to make another hotspot there.. ; ) i think your network isn’t well designed.. Usually a router is one unique costumer.. You can use a switch or a bridge to fix this, then each user must have a unique ip.
Go to their house and steal their Laptop.
Works every time.
This is a popular choice - see Ebay.
xDDD
I bought one once off ebay.es
Admin username was ‘Martin’, password ‘Ruiz’ … 
It had a load of Advanced Traffic Shaping, Advanced Wireless and User Management info on it.
Also quite a lot of unusual WiFi-related porn … the things you can do with an antenna, even the square ones !
Don’t Panic. I had to wipe it an install linux, so you’re safe.
Adrian, give me that grass %)
