Sorry you can not. The laptops internal modem is mostly a PSTN device. This means it can only be used by phone lines. ADSL and Cable modems work in a different way. If you want to connect a laptop and a PS3 to the Internet a Linksys Router with multiple LAN connections must be used. The setup is then: INTERNET | CABLE/DSL Modem | Linksys router | | LAPTOP PS3
No. If your laptop does not have the port required to use the modem and at the very least has a PCMCIA card slot, you must buy the necessary PCMCIA card, such as an ethernet adapter, assuming your cable or dsl modem uses such a connector. There is now this USB LAN (try goggling the image) adapter where you can connect the modem's cable to your laptop, It's cheap, handy and it works just fine.
A router and the modem that will hook up to that router so it can provide the internet. Or you can wirelessly connect to the modem with Wi-Fi. You can also use a dongle for on-the-go internet.
With an ethernet cable from your router or modem
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 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
Yes, you can connect directly via the use of a cross-over cable, or through a connectivity device such as a hub, switch, or router.
i am using it right now, my modem and wireless network tucked away in a bedroom closet, and me at the kitchen table... sweet you dont need to have a wireless connection, you can use an ethernet cable to hook up directly to the modem.
You cannot hook up a hard drive directly to a cable box.
Hook up a USB cable from the system to your hard drive or laptop.
probably a vga
If you laptop has an HDMI output then you can hook it up directly to a HDTV with an HDMI input without the PS3.
