Nintendo made a product just so people can go wifi for pokemon....... I didn't know this. I had wire less before I got pearl so I didn't look into it... that shocks me. but any ways I would just get a normal router as TurboSL1 said they can be sold for $30 watch out though some people will tell you that may need to buy some fancy one that will cost 80+ my grandma fell for this.
Yeah man they always try to sell the expensive ones, i mean you can get one of those, and they work great, you can go outside your house and use it and all, it rocks....
But you don't really need it..... A normal one works great in regular houses.
My house (i live in Puerto Rico) is made out of real concrete, like reinforced with bars and everything...
and it's the WHOLE house, roof and all (Hurricanes Pound us yearly so it's a most really)
and I get wifi in MOST of my house with a Linksys cheap router
Then again my situation is extreme, regular US houses will be totally covered with a normal router
