What router do I need for my Samsung S5PV210 Android 2.3, WiFi

[hougas555]

I am new to this kind of Technology. I just brought my first tablet its a Samsung S5PV210 Android 2.3, WiFi, 4gb hard drive. To be honest, I have no clue what I bought. My kids wanted one for Christmas and I wanted to start off with the cheapest thing just to feel this things out. I haven't received it yet in the mail but I know this much it needs WiFi. (I can tell that by the description) I don't know anything about WiFi, I have comcast internet going in to my computer by a modem that comcast hooked up! I have been told I need a router to work this new tablet. I want to make sure I get this before the tablet arrives and the kids want to play with it. Can you help me with what I am suppose to buy? There is so many kinds of routers I just don't know what to get!!! We aren't planing on running anything else but this tablet other than maybe the Wii! If we like this new device we are thinking about getting a better one..We will just have to see! Thanks for your help
