Yes you can, all you need is an internet router to share the connection, same as sharing connections with multiple computers at home You can use a wireless router or an Ethernet router. The PS3 connects both wirelessly and and through wire connection But according to your internet connection ( if it is fast or slow, or fast enough), you may get some internet lag with some games but not all games. games that need very strong or fast connection may cause some lag when you are using both computer and ps3, but it doesn't mean u cannot use them both. It either means that you need a better connection or you may be too far away to connect with some players for a certain game.
Yes you can be online playing the PS3 and your computer can also be online at the same time. A PS3, PC, Laptop, Xbox 360, or Nintendo Wii have all been online at the same time in some households.
yes
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 do not connect the PS3 ethernet cable to the computer. Just as you connect an ethernet cable to your PS3 to allow it to go online your computer may also have a spot to connect the ethernet cable to allow it to go online. The way the completed system will be set up is that ethernet cables are connected to a router for both the computer and the PS3 and the router is connected to the modem to allow online access to both your computer and the PS3. If you do not have a router you will need to purchase one and until then if you have a computer with online access the computer could be connected directly to the modem which you can unplug and plug in the PS3 to the modem with an ethernet cable. Then you go to network setting on the PS3 and complete the internet connection. In order to use your computer again online you need to unplug the PS3 and Plug the computer back in.
No. A PS3 and a computer can be ran at the same time. A internet wireless network box is able to send a signal to multiple devices.
No, your computer doesn't have to be on when you're online on the PS3, as long as your internet is working, that's all that matters.
no
No they do not
yes you can play 2 players online on world at war on the same ps3 screen
Not online but in regular multiplayer you can
the ps3 store i use it directly on my ps3, i am not sure if you can use it online though The PS3 PlayStation store is available only for the PS3 consoles that have online capability and it is the preferred way to download to your PS3. If your PS3 does not have an internet connection your PS3 can not access or use the PlayStation store . I know procedures exist to allow update information to be downloaded from a computer and moved to the PS3. The best source for procedures is the PlayStation network support at related link
yes u can.
