OK...... I'm giving this forum a shot. Tried Apple's and no one has even replied. My wireless apple mouse sputters and acts off the wall jerky whenever I am copying files to another computer across the network. Im using an airport extreme "N" but that shouldn't be a key to this problem because I had this same problem with a verizon wireless router before the airport. Before I bought the airport extreme I just had my comp hard wired to the Verizon router because that was the only way the mouse would not sputter during network activity. When I hooked up the new airport extreme I didnt hard wire my comp and now it sputters again. Actually I am even losing keyboard connectivity and mouse connectivity at times. I have a mac pro 2x2.66 dual core xeon. Now the card I have in it is a Sonnett Technoloigies Aria Card "N" I talked to them many months ago and are clueless and said it has nothing to do with their card. Actually called them about 4 times insisting that it had to be. Can anyone help me out here and help me figure out what relation the Bluetooth has to airport to where bluetooth barely works during network activity. Are the 2 antennas interfering with eachother or something???? they are real close on the motherboard. I am confused on this one and havent even been giving a clue as to what this might be. And really getting annoyed.
