Please advise on home cable internet setup
I am basically ignorant about networking, don't want to learn too much
about it, and figure somebody who does know can take a minute to give me advice. I have googled, but after a couple hours haven't found a clear answer to my specific needs, or maybe didn't recognize it. I'll just lay out what I have, and what I want to do as clearly as I can and ask anybody to provide answers to my questions. I have Comcast cable TV and plan to order internet service. I have a Netgear FR114P 4-port router. All computers are running XP pro. All computers have a NIC Main computer in basement, where cable comes in. I want to have cable internet access to: Main computer in basement. Daughter's computer upstairs. Son's computer upstairs. But his is acting as a file server networked to a second computer using his NIC and a crossover cable. He wants to keep that. I *don't* want Me/Son/Daughter to share anything except internet access. I can run cable and install boxes myself. I can install the Comcast cable modem myself. But I know I don't know the best way to hook up the pieces. How do I do it - what connects to what? What pieces - besides cable and boxes - am I missing to hook this up how I want? Can you recommend good quality connectors? Will download speed suffer from 3 computers downloading at once, and is there a way to optimize downloads in that situation? Can I expect beefing from Comcast if I don't configure this correctly? Thanks, --Vic |

Thanks, --Vic In my system using a D-Link DI-604 router, the Comcast cable connects to the cable modem. An RJ-45 cable (Cat 5 or Cat 6) connects from the WAN jack of the router to the RJ-45 jack of the cable modem. The router then connects to the NIC card in your computer using one of the four ports. The other computer's NICs connect to the other ports on the router. When you are ready to see if it all works, disable your firewall. Then, after you've got things talking to each other, enable the firewall and (in Zone Alarm, at least) go to the Zones tab and enter the appropriate info.

Just call your local Mom&Pop PC store and ask then to set it all up for you.

I believe Bearman has the essentials correct. As I see it though you will need a
second NIC card for your sons computer that will connect to the FR114P. That way his existing file server set up will be isolated from the internet connection.

: A previous post has given the basics. COMCAST CABLE-CABLE MODEM-ROUTER-PC1 -PC2 -PC3 -PC4-PC5(file server for your son) All cables after the cable modem are patch cables except PC4 to PC5 which is a crossover cable like it is now. You should be able to meet spec's with cat5 UTP. If your runs are long or near other cables, 120VAC, or noise sources, consider cat 5e or cat6. You may want to be use 50ft as your limit on cat 5 even though the spec says a much longer distance. I *don't* want Me/Son/Daughter to share anything except internet access. Turn off file and printer sharing in your lan config. Use: Control panel-Network Have them log into their PC's with login names and passwords. Do not let them use the auto login feature. The XP user manager should handle this. If you have XP pro and formatted the hard drives for NTFS you can also use 'Access Priveleges' to control who sees what on each machine. I can run cable and install boxes myself. I can install the Comcast cable modem myself. But I know I don't know the best way to hook up the pieces. How do I do it - what connects to what? See above. What pieces - besides cable and boxes - am I missing to hook this up how I want? A router with enough ports. One port for each PC except the file server. Two NIC's in the PC connected to the file server. You may be able to connect the file server to the router and restrict access to the server to your son. In this way you would only need one NIC in your son's PC. You'll have to familiarize yourself with the router a bit. The router will use the IP address given to you by Comcast and will have to be configured in a way that is compatible will Comcast's network. The PC'c connected to the router will get their IP addresses from the router and so the PC's and router must be configured in a way that is compatible. Your routers doc's should help you out. Basically I think you need to setup the the PC's and Router for DHCP so the PC's can get IP addresses from the router. The PC's or the router will also need the DNS server addresses, gateway address and the subnet mask from Comcast. These might be obtained automatically by router when it connects to the modem so this may not be a big deal. Their should be a copy of either 'ipconfig' or 'winipcfg' that will help with some of this. You will need to configure 'Client for Microsoft Networks' and 'TCP/IP' Disable WINS Disable DNS Obtain IP address automatically No Gateway Bind TCP/IP to the 'Client for Microsoft Networks' Use: Control panel-Network This is how I'm setup for Comcast but I do not have a router. Your modem and router documentation may have more specific info. Will download speed suffer from 3 computers downloading at once, and is there a way to optimize downloads in that situation? Yes and No. Typical surfing will not be a problem. Downloading files at the same time may be bandwidth limited but how often are you all gonna be downloading a file at the same time? Can I expect beefing from Comcast if I don't configure this correctly? No. Don't tell Comcast, what they don't know won't hurt them and will cost you less. Comcast will want more money if you want them to support this. They'll ask for more money for more IP addresses. You probably can't configure this in a way that will cause them problems, so unless you tell them your doing this, they probably won't find out. In fact, some routers let you copy the MAC address from your PC to the router so that the router will look like your PC to the modem. Check your router documentation. If you switch devices connected directly to the modem you will probably need to re-boot the modem. This is necessay because the modem will 'lock' to the first device it sees when it boots. This is done to prevent connecting multiple devices to the modem. If you don't re-boot the modem it may not talk to the new device until you re-boot it. To re-boot remove power from the modem, don't just turn it off, unplug it completely from all sources of electrical power. Turn off the downstream device, router, pc whatever. Then turn on the modem and let it boot completely. then turn on the downstream device, the router in your case. You may be able to purchase your own cable modem. Check the Comcast forums for recommendations. Also try: http://www.dslreports.com/ http://cable-dsl.home.att.net/ These are good info sites. I have seen many posts praising the newer Motorola Surfboard cable modems. If you purchase your own cable modem, make sure that Comcast will let you use it on their system. I believe Comcast has a published list of approved cable modems on their site. Good Luck |
