I've encountered my first frustrating Mac OS X 10.4 bug. This bug is driving me nuts at home, where I have three base stations covering my house. When I roam between them, I suddenly lose my connection and have to reestablish it. This better be fixed in 10.4.1 or I may be going back to OS X 10.3 until such time as it is, as it really sucks to be in the middle of an instant message conversation or file transfer and suddenly wind up disconnected. I can also try going back to just one wireless AP to cover my house, but I've had problems getting a solid connection throughout the whole house on one AP before.
