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.

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.
