I use a D-Link DWL-G510 wireless adapter (PCI card) for internet access using a Pentium 4 desktop computer. I would like to share the internet access with my laptop, and have three pieces of equipment, but don't know which to use, nor how to go about it.

Equipment available:
1. D-Link Ethernet Broadband Router, DI-604
2. D-Link AirPlus Xtreme G Wireless Router, DI-624
3. Linksys Wireless-G Notebook Adapter

Can someone help me put this puzzle together, so the desktop computer AND laptop computer can simultaneously access the internet?

Thanks.
