No Wifi with closed lid
MacBook Pro 15" 2.16GHz Core Duo Model A1150
I mostly use my MBP in "closed-lid mode" and connected to an external monitor. The problem is the 802.11 signals cuts out when the lid is fully shut. Not completely, but it's either sporadic or "trickles", because a web page will take about 5 mins to load. Therefore, I have to open the lid a few inches to be able to use wifi. It sucks. Another possibly related problem is that the hinge is loose.
Bluetooth signal quality always sucked, but I've learned to live with it. I like my Mac, but shame on Apple for the expensive power supplies with connectors that break so easily.
