How can I tell if a neighbor in accessing my broadband service. he is not accessing my computer?

Answer 1

If you have a router, log into it's interface and check the DHCP status page. It should show you a list of IP's that are leased on your Network. It should also show you the name of the Computer associated with tat IP. If there is a computer listed that is not on your network, then you have someone using you internet,

Answer 2

May be easier to simple black annonymous acces by disabling wireless SSID broadcastn Set a unique SSID name (if you havent already) and disable DHCP. DHCP (Dynamic host Configuration Protocol) is responsible for providing addresses for machine on your network. If you only have a couple PCs then simply do it yourself. Say your Subnet is 192.168.15.1 (this is the defualt scheme for some wireless routers) you could configure your wireless network cards in your PC's to use say...192.168.15.2 and .3 and .4 and so on. This would use a defualt subnet mask of 255.255.255.0 on all of your PC's. If you are not familiar with this...dont let the numbers scare you. This should be documented in the help and user manual for your router. A little effort here will give you peace of mind...and frustrate your freeloading neighbor ;)

Answer 3

Look at the computers connected to your Internet Gateway. You can normally access that gateway using the IP 192.168.0.1 or 192.168.1.1. NOTE: if you haven't done so, change the default password!!

You have two simple ways of securing your gateway:

1) Create a key (WEP key for example). Then, insert this key in your other wireless devices.

2) Restrict the MAC addresses that can connect to your gateway.

You can use one or the other of these solutions, but I recommend that you use both.

Good luck!

Answer 4

Other member have told you how to do that.

So, I just suggest you prevent further more "illegal use" from your "friend" by protecting your network with sercurity code.
