Sharing Broadband Cable Modem (Windows XP/Win98)
Self Vanity

Posted on 01/07/2002 3:54:52 PM PST by SamAdams76

Okay, I just spent the whole afternoon pulling out my hair. I figure there's got to be some Freepers out there with some XP/Cable Modem experience so maybe you can save me some aggravation when I tackle the problem some other day (I've had enough for today).

First, some background. Over the Christmas holiday, I got a new Windows XP system and I gave my old Win98 system to the kids. I bought a cheap 5-port hub, a couple of patch cables, threw a NIC (network interface card) in the Win98 system and using the Windows XP Network Setup Wizard, I was done in about 15 minutes (my new system has a NIC built into the motherboard). The XP Network wizard even created a floppy that I used to configure my old system to see the network - it was that brainless.

It was great to be networked. I shared out the ZIP drive on my old system so I could use it with the new system. I shared the printer off my new system to the old system. I even shared out the dial-up ISP connection so that both computers could be online at the same time. It was great to not have to compete for internet time with my kids, but it was s-l-o-w sharing a 56k connection between two computers.

So I finally gave in and called up AT&T Broadband to have a cable modem installed. Over the phone they asked me if I had my own cable modem and NIC. Stupid me said no, I didn't have the cable modem but I did have a NIC.

Well they came today to install the cable while I was at work. I came home early to test it out. It was phenomenal, incredibly fast! I downloaded a 2.8MB file in 15 seconds where before it would take me 15-20 minutes. But I noticed to my dismay that they had unplugged my hub so I had no more network. There was no place on the cable modem to plug in a patch cable. Not that it would have mattered. For they took over my NIC and configured it to be part of their network.

For the hell of it, I tried plugging the cable modem into the hub. I was able to still access the Internet with my new computer. But my old computer couldn't even see the network, never mind share the connection.

I think I have it figured out. I need to get another NIC card and install it on my new system. I will then use the Networking Wizard to connect my two computers just as before. But will I be able to share the cable connection on the old computer? If anybody has had to deal with this before, I would appreciate some advice.

I'm a little upset with AT&T for not telling me that they were going to be disconnecting my home network when I told them I had a NIC. Otherwise I would have had them bring their own NIC. But what's done is done. At least I have a fast internet connection. And it is incredibly fast. It runs streaming video, the online radio stations sound awesome and when I need to download a program or large file, it is done in seconds!

The response has been overwhelming. Thanks for all the info. I've narrowed my solution to two possibilities:

1. Get a second NIC for the computer that cable modem is plugged into and run my existing hub off that. Configure the network as before but share the internet connection on the other NIC (which means the computer with the cable modem must be on all the time.

2. Install a DSL/Cable router. Connect the cable modem to that and "clone" the MAC address from my NIC to the router. Connect my two PCs to two of the ports on the router. This way I have a firewall and scalability with my network. I am leaning in this direction.

Somebody told me at work today that with the router, I cannot hook the PCs directly into it. That I must plug my PC's into my existing hub and then plug the hub into the router. Is that correct? If I get the router, it will be the Linksys router that Steve W. linked to in reply #3.

Excellent suggestion. I have benefited from Freeper computer advice in the past (and have dished some out as well). Every Freeper has a computer and many of us are computer and/or networking professionals. If all the computer related threads could be contained in one section, Free Republic will quickly become my primary source of computer information. Also, I trust the advice and suggestions of fellow Freepers much more than most of those computing related websites and newsgroups out there.

Lean heavy until you tip over on decision number 2 : )

As I stated earlier the greatest thing about using the hardware solution is that you dont have to always have all PCs on at the same time.

SUCCESS!

Thanks to the help I received here, I solved my problem in less than half an hour when I got home tonight. Forget about ZDNet, CNet, Slashdot and all the other computer websites. The best computer minds reside right here at Free Republic.

I will repeat in detail what happened tonight for the benefit of others on Free Republic who might want to share their broadband connection with other computers in the house.

So to recap, my situation was this: I had a small 2-PC network, one for my kids and one for me and the wife, and I was sharing a S-L-O-W 56kps dial-up connection on that. We had to deal with dropping lines all the time and my computer had to be turned on and connected to the ISP in order for the kids to use the web on their PC. So I went and signed up for broadband internet through AT&T. Lo and behold, the installers came, unhooked my cheap hub, and took the NIC hostage for their own WAN (wide area network) in which I was now just a node. In order to get my network back, I had to either buy a new NIC or get a router (which is essentially a hub-like device that connects two networks together).

Nearly everybody suggested getting a router instead of getting a second NIC and that is what I did. Some, like innocentbystander, suggested the Netgear FR314 router, and many others suggested the Linksys BEFSR41 Cable/DSL router. On my way home today, I dropped into a computer store and both models were carried. The Netgear looked like the superior piece of equipment but it was $249 while the Linksys was priced on sale for $79 (normally $129). So I grabbed the Linksys figuring if it didn't work, I'd get my money back and get the Netgear.

Well I got it home and I was real impressed with how easy it was to setup. Simply shut down everything, hook into the router and fire back up. I ran the web utility and didn't really have to change anything as my cable ISP assigns an IP dynamically. So I rebooted everything and tried to get the web connection working.

Nada.

But I remembered some Freepers in this thread talking about how you might need to clone the MAC (hardware) address from the NIC card to the new router. See, the cable companies only want one device per household using the connection. This gives them an opportunity to hit you up for another $9.95 per month for hooking up additional systems. So they configured it so the connection would only work on that one NIC.

So back to the web utility I went and hidden deep inside the menus was an option to reassign the MAC address for the router. So I did an "ipconfig /all" in a DOS session and retrieved the MAC address the cable company wanted to see. I programmed that address into the router and when I rebooted, BAM, both computers were on the web at breakneck speed. And the cable company is none the wiser, as all they see is my new router with the same MAC address as the NIC card they originally installed to.

BTW, it is not illegal to share a broadband connection in your home. The ISP's just aren't going to show you how to do it yourself because they would rather make the extra $9.95 a month doing it themselves.

When I got that accomplished, I was all set to brag to the rest of the world when I realized that my original network wasn't working. That is to say, my shared resources such as the printer, Zip drive, files, etc., weren't being recognized across the network. In fact, I couldn't even recognize the other computer. I tried pinging them and found that I could ping the Win98 system from my XP computer but I couldn't ping the XP computer from the Win98 computer.

Then I remembered something else that was said on this thread. When the software firewall is activated under XP, you can no longer share resources on the network. The cable company activated the software firewall when they made the connection.

Well now that I had my router, which is a hardware firewall, there was no longer any need for the software firewall. So I deactivated it on XP. Suddenly I could see the network again and vice versa. Lesson learned: Hardware firewalls are better than software firewalls.

So I now have my network back and both PCs are surfing the web at broadband speed. For those with dial-ups, you have no idea what you are missing out on. Despite the hassles I had to go through the last couple of days, I will never go back to dial-up again.

I hope this reply is helpful to others contemplating sharing their broadband connection. And much thanks again to all those who contributed their wisdom to this thread.

The Netgear did look nice. If I hadn't spent so much money already over the past two weeks, I would have gotten it. Perhaps as my network expands, I'll upgrade to it.

Since I unconfigured the XP software firewall (so I could use my network), is the Linksys router all the firewall I need? Or do you suggest something extra? I downloaded the free ZoneAlarm program last night but haven't installed it.

I use Zone ALarm on all four of mine. Zone Alarm is very configureable! Do pay attention to what you permit to access either Internet or local.

Thanks for posting this and updating it as you went along. I printed it out and used it to solve my cable modem / Linksys connection problem. I should have known that the MAC address would save the day, I LOVE Macintosh computers, even though I'm forced to use PC's (Pieces of Crap) at work! MAC's rule! 8^)

Glad I was able to help you get your Linksys working (after many here helped me). About a week later now and it is still working great!

I got the Lynksys router system that also has the WAP (Wireless access point).

I just broke down and added wireless here. It's fantastic, and the new equipment has encryption so don't have to worry about that aspect. Glad I waited for it.

Your router will be the only IP address your ISP sees. Your machines will be will get their address from the router.

I have had as many as 4 computers hooked to my router.

The Linksys is the way to go, I have had friends make one of their machines the server, and while it works, they were much more pleased with the router.

You may have to register your Router MAC address with your ISP. They keep up with you by your NIC card MAC address and modem serial number.

I would back the many here who said to get the Lynksys wireless router. I bought the router, two USB wireless adapters and a PCMCIA card for a laptop and in 30 minutes I had four computers hooked up through one cable modem. Two of the computers use Win 98, the laptop has ME and one computer has XP.

The only caveat I would add is Get the LATEST versions of all Linksys hardware. There IS a difference in both the hardware and its associated software, and the late stuff works great!

I'm currently running 4 computers hard wired into the Linksys Wireless Router, plus one desktop via wireless and one portable via wireless. Running WinXP, Win2000 and WinME.

Good point. Also, in the last few months, wireless has gone through the roof. Both in usage and price. The router I bought has gone up $30 and the cards have gone up $25. This was at Best Buy. I'm sure one can find better pricing online, but I have no patience.

You know, I THOUGHT those prices were higher! I paid $160 for the wireless Linsys router and $89 each for the portable card and the remote desktop unit at Office Depot. Was sure I had seen them cheeper before, but........ they do work great! I tried the portable from another building about 300' away it it worked fine.

Amazon and Buy.com usually have good prices on the Linksys BEFW11S4... also www.pricewatch.com lists prices of all sorts of computer equipment from various vendors.
