I have been having seemingly unexplained wireless dropouts under OS X as of late. What will happen is that the connection will suddenly drop, and then come back 10-15 seconds later. I don't know if they would have occurred under 10.5.6 (I'm currently running 10.5.7) as I had not used my MBP with the same wireless equipment until after having upgraded to 10.5.7. However, I do know that in the exact same room using Microsoft Windows I experience no such dropouts. The other wirelessly-connected Mac, the 24" iMac in my signature, does not experience the same dropouts. Is anyone else experiencing something similar? Does anyone have any suggestions?
