If you have a Belkin you must change the password(WPA key).
The PS3 allows you to connect to an existing wireless connection
sometimes your connection may get bumped off by a computer using the same connection to fix it use an ethernet cable and connect the router and the PS3
You can use a wireless connection if you have a wireless router
I found I preferred a wired connection, but others may have had different results. I did have a good connection, but I wanted a perfect connection and the best connection. The PS3 connection test showed better results for the wired connection compared to the wireless for the internet connection. For the Bluetooth wireless connection of the controllers and other accessories the PS3 is excellent
No the first part of the connection process on the PS3 searches for an ethernet connection, once it does not find one it then searches for a wireless connection
All PS3 but the first 20 GB model are wireless. That means if you already have a wireless internet connection they can connect to it.
Only for the PS3
Buy a wireless router and hook it to your cable modem. PS3 does not provide broadband you must purchase it
no you need an internet connection with WiFi
With tools obviously!
already have a wireless connection
buy a new one
