My problem is that I cannot access the internet through my LAC. I enable the connection and it will connect and send packets, but will not receive any packets. I have no problems enabling my wireless connection and connecting to the internet. The wireless does like to disconnect and reconnect about 3 or 4 times an hour which is another problem I have. I believe this LAC problem started around the same time I was trying to get shared music between my computers on iTunes. I was trying to allow for connection on port 3689, but everything I did was unsuccessful. Any suggestions for any of these problems I'm having?
