actually....sleep with her first, then take pictures (while she's sleeping), then change the password.

Well, he should be able to sleep with her based upon his generosity for said wireless usage...
pictures...
after he changes the password, she'll either do him again to gain access, or he can claim it as "payment" for the free internet.
either way, she's a whore.

It's only a problem if you don't want someone reading your emails, checking your bank accounts, and installing viruses on all of the computers on the network.

I am curious how one goes about accessing the other computers. Is it easy to do?

I have a wireless router in the office for a couple of computers I use. A person in my office complex asked if she could borrow my wireless access code as her SBC connection was down. I said sure thinking she would have it fixed in a day or so. She hasn't done so. I could be an ass and just change the pass code, but not really PC unless I know there is a problem.

So I ask...is there a problem? I have sensitive information on my computer, but have no idea if it can be easily accessed by someone using the same wireless router.

What is my exposure, if you will? Anything to worry about?

I was just joking.

In reality, it depends on your specific security setup with shared folders. If you have any open folders, whether it is a Network Attached Storage(NAS) server or a folder on a computer that anyone can access they can get to it too if they are on the same network. For instance, I have a local Linkstation networked hard drive. The public folders would be accessible to anyone on my network. Any password protected ones would be visible.

Go to "My Network Places" or "Network" and see what folders are there.

They can't just get into any other computer. You have to grant that access.

Now, someone with super hacker skills could probably do it, but in reality that person could break into your network regardless even with a password.

I checked the My Network Places, and the only thing listed is a MY Websites on MSN, which I don't have. On the left there is a section called "other places" which lists the computer desktop and My Documents, which would be a problem.

From what you are saying, it doesn't appear as though another person could access what I am viewing online. Passwords would be a concern.

you can ban her mac address/machine.

in addition to password security, you can also, and you probably should, only allow approved machines (by mac address) access the router. i'd also turn off visibility/broadcasting so it's not easily discoverable. also, a moat with gators covering the perimeter of the router's effective range

Do all 3, in order of Doug, Douchebag, and Hawg.
