Answer : Problem: wireless install

If your ISP has provided a wireless router, you just need to receive that wi-fi signal on your PC. For the same you would surely need a Wireless Adapter, which can be USB or PCI card.
In terms of vendors, there are many, ATT, Dell and many other better ones. This goes with your budget.
Range and reliabilty are other aspects. For webcam/talk , you would need a adapter.
