My boyo has a PS3 and has asked if it can be hooked up to the internet. I've got a Linksys wireless router (2 actually, the 2nd is cascaded) and the PS3 has a LAN port. So the mechanical connection is pretty straightforward. What issues can I as a homeowner, network manager and billpayer expect? - will it dramatically affect network speed? (more than just another computer on the network) - are there charges I need to consider? - do I need to configure my router/access point firewall? - are there security risks? - etc. Also, what will he be able to do once he gets it hooked up? Firmware updates, multiplayer games? software downalods?
