Yeah you just change the settings to wireless rather than wired.
Purchase an ethernet cable, either cat5 or cat6 long enough to run from the back of your PS3 to the Modem. If your modem has something already plugged into the ethernet, you need to unplug it and plug in the PS3. If you want to be able to use both without having to switch the plugs you need to purchase a router that you connect to the modem and then connect everything to the router.
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.
If the Modem was already working and for example you unplug your computer and plug in the PlayStation 3 it will work after you go to the PS3 network settings and make the connection. It will be easier on you to find a used router and plug it into the modem and then plug both the computer and PS3 into the router.
After you have broadband or DSL internet service then you need to purchase the equipment needed to connect the PS3. The PS3 can be connected only with WiFi or an ethernet cable to your modem or router
A PS3 has WiFi and you can put the router next to your modem. The only thing the back of a PS3 uses for the internet is for a wired connection with an ethernet cable to your router or modem instead of a WiFi connection
You must subscribe to an internet service and have WiFi modem or router or connect an ethernet cable to your PS3 from a router or a Modem with internet service
The PS3 does not have a router. It can go online with an ethernet cable connected to a router or modem or with WiFi from a wireless router or modem
You connect your PS3 to the router and then to the internet modem with ethernet cables. The PS3 has a single spot in back to plug in the cable and the router has many spots in back to connect. The router will be connected to the modem. Once the cables are in place go to the settings on the PS3 and then Network connections.
You are supposed to connect an ethernet cable from the modem to whatever device that needs an online connection and if you have 2 or more items connect the router to the modem with an ethernet cable and then connect the devices to the router with ethernet cables
If you have a router the ethernet cable connects to it. If you have another item like a PC connected to a modem you could disconnect the ethernet cable from it and plug in the PS3 until you purchase a router.
You purchase a router and connect it to the cable modem and then connect everything to the router. Otherwise you have to unplug whatever is connected to the cable modem (for example a PC) and plug in the PS3 . Whatever you have unplugged is no longer connected to the internet until you unplug the PS3 and plug it back into the modem. Once the PS3 is connected to the cable you need to go to network settings on the PS3 and set up the network connection.
If you connect your modem to the router, and then using one of LAN port (router's) connect the PS3 to the router, you will not interfere with wireless signal at all.
You need an Internet source, but you can also connect to the PS3 wired with an ethernet cable plugged into the back of the PS3 and into a router or modem.
If you want to know if you need WiFi to get online then no you don't. You can connect an ethernet cable from your cable modem or from a router to the ethernet port in the back of a PS3
Find a Broadband or DSL internet provider or if you already have one and are already using it connect a router to your modem. Then simple connect an ethernet cable from your modem to your router and one from your router to your PS3. The cable that was going from the modem to your computer now goes from your router to your computer. If you are not using the internet service before then just connect th ethernet cable from your new modem to the PS3. Then if you do get a computer just buy the router and the ethernet cables then.
If nothing else is connected to the modem you can use a ethernet cable to connect the ps2 to the modem and the internet. If you also have a PC then you need to put a router between the modem and PC and also connect the PS2 to the router which will allow both the PC and PS3 to work off the same modem
The PS3 does not have a router. you must purchase one to connect online if you need a router
