Yes unless you want to have to unconnect and reconnect whatever you have plugged into the modem now. It's very simple as I had a Comcast modem also and went to Best buy and Purchased a wireless modem for $80 and later found I could have purchased the same or better equipment cheaper elsewhere. The modem gets plugged into the router and everything else that you need to go online gets plugged into the router or gets set up for wireless connection. I found that the PS3 held the connection perfectly when it was wired and so even though I purchased a wireless router I also purchased a 50 foot Belkin cat 6 gold ethernet cable on Ebay for $20 incl S/H and set up a wired connection.
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
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
Yes and no. The iPod Touch uses whatever internet the local router is using, so if the router you are using is connected to your Comcast Internet modem, then you are using Comcast Internet. If the router you are using is using another modem, like AT&T modem, then it is using AT&T internet.
An internet service provider and a modem or router you can connect an ethernet cable to or a WiFi Modem Or router for a WiFi connection.
Yes, this will connect a computer to a second port on your modem/router
Yes.
yes you can
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
there has been a misunderstanding between modem and router. some people use only a modem to connect wirelessly and some use a modem and a router. The fact is there are two types. first type is a modem with built in router, second is router itself. this will clear your mind. you don't have to buy a router to go online, just a get modem with router built in
Purchase a router and an ethernet cable and connect the router to the cable modem and then connect everything to the router if you get the wireless router then you connect wired devices to the back of the wireless router and you can go WiFi to connect the PS3 or connect it with ethernet cables for a better connection.
You have to have a router to connect more than 1 item with Comcast Internet unless you also got the wireless router from Comcast. You can either go out and purchase a router either wireless, both, or Ethernet. I purchased a wireless router and then decided I liked the wired system better and purchased an Ethernet cable to hook up the PlayStation 3 because I saw that the router also had 4 Ethernet plugs in back. So you still need to purchase a router even though you have Internet access with Comcast.
not the modem it self, but with an internet plan. im not sure if comcast's high speed internet offers wifi but i know Xfinity does
