What you all need to understand is that there is no magic answer to fix these problems. In many cases a new router is NOT the answer. Most people just do not know jack shit about networking and wireless. Which is fine, however the real problem is that these console game manufacturers can't program their games online play easy enough for networking noobs. So any smuck can go hook up a wireless router and get wireless. But configuring DMZ, firewalls, understand what a port and IP is that is not stuff that typical console gamers have a clue about. Quit blaming the router manufacturers because they do a much better job.
The best help you can receive is this:
- Open necessary ports for PS3
- Open any ports used specifically by the game (which is retarded they don't use standard PS3 ports)
- If your router supports UPnP enable it (caution this is a security risk UPnP is a horrible idea)
- Make sure your wireless connection is strong
Now you might say I am being too general, "I need it step by step". Well I'm sorry to tell you, that you must figure out yourself. Reason is that everyone has a different router many from different manufacturers that have a different configuration interface.
Bottom line is if you are not able to just plug and play your PS3 games online, you either need to find a friend that can fix your problems, pay someone to do it, or learn how to do it yourself.
Perhaps not the answer you were all looking for but at least it will stop you from running around like chickens with your heads cut off.
