So, the husband went out and bought a new surround sound system. Hooked it up, connected the internet, etc. Now my iMac won't connect. Keeps telling me that I've timed out or the server is busy. It will connect to the neighbor's unsecured network (which is sloooow), just not to our home network. His MacBook, the surround system and the DVR are all working fine and have full connectivity to the home network. Any ideas?
