Sorry if this has been asked before but I googled and searched the forums and haven't been able to find this question. When I try to wireless sync my phone to my itunes it kills the wifi. It still shows that the phone is syncing, though taking forever. No other device in the house can load a webpage though. It kills everything until I go reset the router and cable modem. The same thing goes for streaming music from my computer to my apple tv through home sharing. It kills everything but the music still streams just fine. Is there some setting I have off in my computer or something? Any help would be much appreciated. I just updated to mountain lion last night but this was happening with lion and snow leopard before as well. I have a mid 2010 13 inch macbook pro. Time Warner is my internet provider.
