Location Description: Large, long 3-story home with massive "thick wall" construction. Large backyard with swimming pool.
Computer Locations: (1) WinXP system on 3rd floor, far left side of house. This location has the cable modem. (2) WinXP system on 1st floor, middle of house. (3) Win98SE system on 2nd floor, far right side of house. (4) WinXP notebook roaming the backyard pool area.
Current Configuration: System-1's computer is hardwired to a Linksys 4-Port Router/WAP. System-2, using a wireless PCI NIC, is at the EXTREME edge of coverage but does maintain a signal. System-3, also using a wireless PCI NIC, is beyond the current wireless zone of coverage. System-4 should be free to roam anywhere (inside or backyard).
Goal: To expand the existing single zone of wireless coverage such that any and all computers (in-house and backyard) can obtain a connection to the networked resources of each other (files & printers) and can also share the cable broadband connection to the internet.
Additional Comments: Existing Linksys hardware does NOT have to be utilized. Any and all items can be replaced. Due to structure and appearance considerations, hardwired connections between system locations would not be feasible. Specific notes to a particular manufacturer's product/model# and configuration comments for each item would be preferred over a generic answer.
Can this be done? THANKS!
