Thankyou all for your input as this is far better support than service providers can give.
My hardware as it stands is dynex switch, DI-624 dlink router, and DI-704up dlink router. Linking together at the first building where the internet is a wireless or Motorola Canopy 900mhz subscriber module, this is connected to the Switch that is connected to the DI-624. also from the switch is Cat5 cable to the 2nd building where I have the DI-704up connecting the home computers, printers. The DI-624 has 2 Business Computers and an IP camera. The diagram of swimmers is very close for the first building, and I could connect the camera to the switch. I am on a medium business package with xplornet and this includes 5 static ips. the subnet mask is 255.255.255.224 and the static are all in order xxx.xxx.xxx.xx1 through 5
