Yes just plug the cables into the modem and it should work the same
connect the two xboxes to the same modem
Probably has to do with your connection. Try turning off your modem and restarting it.
maybe it is your Internet connection if you have wireless get the modem.
First you must have a working lag switch, that mean if your on a rooter, the lag switch must be between the modem and the rooter, not the ps3 and rooter. If your on modem, your put it between your modem and ps3.
turn your router/modem of then on then wait 30 seconds one you've waited go on to modern warfare and search
World war 3
Because it has violence and shooting
Because you use different modes to access it!
Yes you can because the modem router has a modem built in. There are different types of modem routers that suit different needs. If you are only going to be surfing the web you will need a "N" modem router, if you are going to be sharing files then you will need a "N+" modem router and if you are going to be gaming e.g. connecting to a Xbox 360 or PlayStaion 3 you will need a "N+N" modem router, I would personally recommend Belkin modem routers. Hope you find this useful!
Since this was posted under Cable Modems, I'm assuming that you are asking about the (Data Over Cable Service Interface Specification (DOCSIS) cable modem which allows different cable companies and different cable modem manufactures all to adhere to a uniform set of protocols and modulation schemes to allow for inter and intra market competition. Go to Wikipedia and search DOCSIS for more information if that truly was your question.
No, Don't think it because it's in modern Time. Maybe downloadable as a mod, but not in the game I think. There will be a zombie mode. Just not Nazi zombies. There will also be zombie dogs. Zombie mode is an exclusive of Treyarch who develops the World At War and Black Ops Call of Duty games and not part of the game development of Infinity Ward who do the call of duty modem warfare series games
Most modern laptops already have inbuilt modems
