are modems and routers the same?
and how do i connect the router or where do i connect the router if thats different than a modem
It depends upon what the Rogers guy installed…
If he just installed a modem, that only connects to a single computer.
To go wireless, you’d need a wireless router (which lets you share the Internet connection among multiple computers in your house) plugged into the modem, plus a wireless adapter for your computer.
If your house is fairly big or there are multiple walls between the room where the modem sits and the bedroom, you’ll want something like these, which provide the greatest signal strength and range.

If the rooms with the modem and computer aren’t far apart, then you could go with Wireless-G equipment instead of wireless-N.

Now if the Rogers guy installed a wireless router (which can connect multiple computers) then you don’t need to buy one yourself. You’d just buy a USB wireless adapter.
If you only need to connect one computer, there’s another option. You can use a powerline adapter kit instead of going wireless. These adapters plug into the AC wall socket in each room, and aren’t affected by wireless interference or signal strength problems. Basically you convert a pair of power plugs in your house into network jacks.
