Unsecured Network

[¿Que?]

Recently, I had my internet cut off. I finally paid the bill and got it restored, but a funny thing I discovered during that time. Someone in the apartment complex where I live has a visible, unsecured wireless network. What's more, I was able to log into the router with u:admin p:admin. I realize I could totally fuck shit up, but that's probably not too smart. I checked for shared volumes, but couldn't find any at the other two registered local IP addresses (I got this info from the router ;)). Anyway, I have no idea who this network belongs to, and I think I should probably let the person know that they have a very unsecured network. I also think someone more advanced might be able to hack into their computers after accessing the local network.

Any thoughts, advice, comments?

It certainly would be nice to inform them that they have an unsecured network, but stuff like WEP security doesn't stop those with real computer knowledge from using a persons network.

So don't mess any of their stuff up and let them know what is wrong if you can.
