can I switch back and forth between DSL ethernet modem and AirPort ?
I use Earthlink DSL connected direct to my iMac by ethernet cable from my modem and the service is very good . . . ever since I installed Leopard I noticed up in the top menu bar that AirPort is ON and usually shows 4 or 5 names listed and only 2 or 3 have the Lock icon . . . I have to assume AirPort is detecting signals from the apartments above and next to me . . . I do not need a wireless connection but I am curious to see if my iMac will actually join one of those networks so how do I temporarily try that and then go back to my regular wired DSL service ? . . . also, I may start renting out a room in my place and the girl will undoubtedly have either a Windows or hopefully a Mac laptop and will need wireless so I would appreciate advice on the best equipment to buy that both Windows and Mac laptops can connect to wirelessly . . . thanks in advance for any advice
