How can I monitor who is on my wireless network, and can it be done using existing software in Windows XP?

I have a basic wireless home network, I have made a few tweaks and whatnot with regards to the security, but it seems that someone is accessing my network. What can I do to see who is on my network at any given time, and can I disable their ability to log on to the network.

You should enable encryption on your wireless network. Make sure the encryption key matches your router, and the computers on your network. there are several programs available which you can download for free to see who is on your network. Check the wireless networking forum and FAQs at dslreports. com.

What you really want to do is lock donw your wireless network so no one can steal bandwidth from you can cause other problems for you.

Setup Procedures:

Before you start you will need some important information!!!

If you are already connected, go to the command line

Start-->Run-->cmd

Type ipconfig /all

You should see something like this:

Windows IP Configuration

Host name . . . . . . . . . . . .... : MyComputerName
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . ..... . . : Hybrid
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . : No
DNS Suffix Search List. . . . . : MyDomainname.com

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : MyDomainname.com
Description . . . . . . . . . . ............... : My NIC
Physical Address. . . . . . .......... . . : Unique MAC Address
Dhcp Enabled. . . . . . . . . . ........... : Yes
Autoconfiguration Enabled . . . ..... : Yes
IP Address. . . . . . . . . . .............. . : 192.168.1.42
Subnet Mask . . . . . . . . . . ............ : 255.255.255.0
Default Gateway . . . . . . .......... . . : 192.168.1.1
DHCP Server . . . . . . . ........... . . . : 192.168.1.1
DNS Servers . . . . . . . . ............ . . : Unique IP Address
Primary WINS Server . . . ....... . . . : Unique IP Address

Write these down or save them someplace for future reference.

If you don't see anything like this you will need to get from
your ISP.

After you have all this information and have all your hardware
connected similar to the basic diagram above you will need to
configure your Router.

Open broswer like Internet Explorer, Firefox or some such.

In the Address box type:

http://192.168.1.1

If you get prompted for a Username and Password type these,

ADMIN/ADMIN

We will change these later.

You should be take to the Setup window for the router. Use
all of the recommended settings below. they will help you
configure your router for safe wireless use and wired use in
your home.

Whereever you see something in angle brackets <...> you must
supply. when you create a new password use both upper/lower
case letters and numbers. Write it down, memorize it, eat the
paper you wrote it on and never share with anyone. Just kidding
but you should not take this lightly. Anyone who know this
information could make it so they could hijack your Internet
connection. this could have sever legal consequences or imbaracing
at the least.

Have fun but be safe!

You can always email if you have questions.

if you have multiple computers on your network then each computer is assigned a computer name(my computer>system properties>computer name tab) so if you open your network monitor you can see the computer name, not the user.
If you have one computer then you can password protect the account with internet access.
If someone outside your house is accessing your network, you can get only their computer name, but if only you were a hacker can you get his name. so your best bet in this case is password protect your network.
