Network chip with arduino

Ive just pulled apart an old HP psc 2510 photosmart printer. And found the network card (with wireless and ethernet) inside. It has an onboard broadcomm bcm5221a4kpt and attached is a rangestar wireless chip. And it looks like it has some sort of phillips cpu.

Now I was wondering if it is possible to talk to it with the arduino. It has an eight pin header (i was wondering if two of them are power and the rest some sort of ic2 or parallel interface) with black, white, green, black, orange, grey, blue, and, red wires.
