Can I block a single user from accessing my wireless?

[rob22941]

Ok, I'm in college and my roommate hasn't paid me his share of the internet bill or electric for that matter for the past 3 months and each time I ask for the cash or if he has it he says no. So I'd like to screw with him just in time for finals. You mess with me I mess with you.

Is there a way to block his ip address from accessing my router for internet access? I set up the internet and the works. I used windows 7 to originally set up the internet but I also have 2 other computers with ubuntu built on. I don't care if I use ubuntu or windows to block him. Do I need to get on his pc to get his ip or can I view who is logged on through my pc? Thanks much amigos.

If it's your router, and it is also the DHCP server, you can assign a static lease based on MAC Address. If that address is outside the subnet, it might not work well (eg 127.0.0.1). A static address will quickly bypass this "security". The router itself might also have (MAC address) filtering options.

If it's something clever he will know I'm screwing with him. And he'll accuse me immediately. I do however like the idea. I think it will just be most appropriate to simply cut him off of my wireless.

I'm not quite sure what you mean. However I would just change the password but I have a total of 3 roommates and I don't want any of them to know my intentions.

Starting to sound a bit more sinister :-k
You should be able to block access to the router from the router itself. The manual should be able to tell you how to set up a static lease (reserved address) or filter by MAC address. If you'd care to mention router make/model, that info may be on Web, as well... but if you're only cutting off a deadbeat roomie, why the clandestine activity? If it's for vengeance alone, this is the wrong place for help...

Well I think it would be useful knowledge. I also would like my roommate to not rely on ends of my wallet. I'm going to take a closer look at ex-parrot.

I use mac address filtering. Just add the mac addresses of all your stuff and then either dont add his or add his and put a check mark next to it so it doesn't allow him. This is how it works on my belkin anyways.

Doing it now. Thanks all, I also found what I thought to be a useful link:
