Ha! I wouldn't put it past them. I'll try when I get home? An this is done by putting a certain number into the safari browser, right? Any hints as to what number that might be?
Also, it seems like my best bet moving forward is to try and adjust the settings on the router? The iMac is still having problems connecting occasionally. When it doesn't connect, it's consistently been on that router address I reported in my original post, and when it decides to work a bit later, it's on a different router address. Again, my wife's laptop seems to be connected, I'll check her ip when I get home.
I couldn't get in to adjust the router settings, but I was able to connect the MacBook Pro today when I got home. I quickly looked at the router settings, and it looks like I am connected at 184.108.40.206. My wife's Windows 7 computer is connected to the same connection. It looks like the problem connection is when the computer tries to connect in our apartment at 220.127.116.11. Is there a way to not allow the MBP to connect to the 18.104.22.168, or force it to connect to 22.214.171.124?
