It enters a "splitter", where one cable gets routed to both the Internet connection and your DCM Cable TV system.
- One of those wires goes to a "router", where it is split into at least 4 other wires, which are "patched" into four locations around your house.
- You plug your PC into one or more of those locations.
- There's a map of what's configured stuck to the inside of the door of your little metal distribution box.
- Go buy a wireless router. The most common is a Linksys, and there are several models. Ask the man about the best you can buy and buy it. Don't skimp here.
- Open the door to the little metal distribution box. Have a medium size glass of Scotch on hand.
- Starting from the top of the box, locate the coaxial cable coming in.
- Find the splitter - one coax comes in, two go out.
- Follow the coax that goes to the cable modem. This one will go to a box that has an "ethernet" wire as an output. The one you DON'T want will go to a 4- or 8-way splitter/amplifier to send TV signals to your rooms.
- Follow the ethernet cable to the next box in line, which will be your ethernet router.
- Closely observe the wiring connections. You are going to replace this specific little box. Pay attention.
- The Linksys wireless router will be the replacement for this box. You can use the Linksys router as a complete replacement, while also supporting a wireless connection.
- With your computer connected, determine which of the ports on the router is "alive" by noticing which lights on the router are on. You need this information in the next step.
- In this next step you are going to "patch" around the router. This is really very simple, but can be scary if you're not into this techie stuff.
- Your objective is to (temporarily) eliminate the router, and make a connection from the ethernet output port to the patch cord input for the wiring connection that goes to your pc.
- Follow the ethernet cable that LEAVES the cable modem until you see where it ENTERS the router.
- Unplug it from the router.
- Follow the ethernet cable that LEAVES the router to the patch port that goes to your pc. Unplug the ethernet cable from the patch port and replace it with the free end of the ethernet cable that comes from the cable modem.
- This action should have bypassed the router, leaving your PC functional, but only in one location in your house.
- Remove the router. Unplug the rest of the cables, including the power supply cable for the router.
- Go back to your "office" and verify that your PC is still working and connected to the Internet. If it is NOT, you need to patch the modem output into another input port until you find the right wire that goes to your PC. (This is the point where you call John Pod and get coaching if you've already used up your scotch supply.)
- Now you can follow the instructions for the installation of your Linksys Router. Functionally, it will go into the hole left behind by the removal of the DCM-supplied router. You can put the Linksys router in place, replacing all the wires, and things should work just like they used to.
- Then you can implement the wireless functionality.
The stuff works. It apparently works on Vista as well as XP. The wireless apparently works, even when it is enclosed in the metal distribution box. Wow.
Many thanks to Jim Taylor who tried all this stuff and demonstrated that it works.
The settings Jim Taylor used were:
The changes made were:
A. Linksys Setup page
- Network Address Server Settings (DHCP)
- Starting IP Address: 192.168.1.100 [don't remember the original]
- Maximum number of DHCP users: 5 [was 100, I think]
B. Linksys Wireless Security Page
Changed WPA Algo to AES
NOTE: If you want a wireless printer, you'll need to modify this procedure to support the connectivity you need.
