I have never touched a mac so I am going to have to state the obvious. If you disconnect the cable then you are obviously going to use your network connection. If it were a windows pc you would then have to use the wireless network utility to scan for available wireless networks, select a network to connect to and then enter the password. It would then tell you you are connected etc. I can't see why anything else would have changed on the mac side. The only thing which would be different is that any wireless device would now see the additional trend wireless network in addition to the shub.
