Hi with one computer being 5 years old,  a ps3 and currently building a computer what do i need to get internet to all of them. The ps3 must connect wirelessly, which it has wifi. For the computer im building, for it to allow wireless internet do i need a motherboard that has wifi? or can i buy a wireless usb adapter?


Or it is possible both computers can connect via 2 ethernet cables of a wireless router.


Im looking at the Dynalink RTA1025W ADSL2+ Wireless modem router, so would i just need that, plus 2 ethernet cables or a wireless adapter to get one computer connected wirelessly or a wifi motherboard. How ever im getting a $200 motherboard and the cheapest wifi one is around $333

Thanks
