How Do I Trade Pokemon From White To Soul Silver?

I Would like to trade pokemon from my Pokemon White to my Pokemon Soul Silver, However, my internet model appears to be to advanced to work with the DS so Wifi Connection cannot be used, However, i was wondering if you could do it another way, for instance Pokemon White has IR, but i don't know about Soul Silver. I have 2 DS so i can trade via IR, but I don't know how to get Soul Silver to use IR. This is probably quite a stupid question, but i would really like an answer? Thanks :)
