I'm taking care of a house for 2 weeks, and, well, it's not exactly the most exciting thing. I asked the owner if I could add my computer to his wireless network, and he said it was fine. I'm not sure he knows his network as well as I believe he does, but I asked him, and at the time he said it wasn't encrypted.
His network is up, in fact, I'm using his daughter's (my friend's) computer right now to write this. It's a wireless network with D-link, I'm getting a signal on my computer (I can set his network as the one my PC runs on) but I can't see any of their files on the network, or access the internet. When I look at the workgroup on my PC, I see only my computer. I can't detect my own computer from the daughter's, but I haven't tried to do that all that much. Her computer is old, confusing, and horribly taken care of (But it still has XP).
I can't access the admin computer because he had taken it with him on the trip.
I gave as much detail as I could, if you have any questions, please ask, and if you have an answer, please let me know.
Also, if I need any passwords or keys, let me know, he'll be phoning to check in every day, and that's when I can get them off him.
