View Full Version : Network printer kicks Macbook out of WLAN

Jun 5, 2009, 04:54 PM
Hello everybody,
I have a very annoying and (at least to me) puzzling problem:

If I turn on our network printer then my MacBook gets somehow kicked out of the wireless LAN. The Airport icon indicates a connection, but I am not able to access the router menue. After turning the printer off, I am still not able to connect until I restart the router.
However, if I disable the WPA2 encryption before turning on the printer everything works just fine: I am able to print, access router menue/ internet.
Both, MacBook and printer have reserved IP adresses. There are up to three PCs connected to the network, but the problem occurs regardless if they are connected or not.

Every comment is highly appreciated!
