Networking Windows XP, 95/98, and Network Printer

Wow, What a Way to bring in the New Year!



Needed to help a buddy hookup a network between two Windows XP computers (one a Toshiba laptop, and the other a new Dell Vostro desktop), two old Dell Windows 95 computers, a System 2000 computer, and a networked Brother MFC FAX/Printer/Scanner/Copier. Well, he had a network working with NetBeui, using a network HUB, and a strange Bridge setting on the Toshiba laptop XP system, but when the new Dell Vostro desktop was installed, the network stopped working.

After my buddy had spent four hours on the phone with Dell Tech Support, they decided to send out a repair guy to try a new motherboard. This was after Tech Support tried everything under the sun software wise to get the system to function. My friend is still in the stone-ages for Internet connectivity. He is on a Dial-Up Modem. No high speed service is available where he is located. To far away for DSL from the phone company, and no high speed cable service in his area. Satellite communications is still questionable as far as he is concerned. So, can you image when the Dell Tech support person got online and tried to control his new computer? Slow as molasses for the mouse movement. Got to hand it to Dell, the person went none stop for four hours straight, even though the problem was not fixed.

The Network Problem

Sometimes the Dell Vostro would show up on the network and sometimes it would not. This was the case with even looking at itself on the network. Sometimes it was there and sometimes it was not. Dell tried turning off Windows firewall protection and Norton Internet Firewall Security but that did not seem to change anything. So, that is when they decided to go to the next level, and try the hardware. Because of the holiday season, it was going to take a couple of days to get the motherboard. So, we put our heads together and tried tackling the network issue ourselves.

Since the network was on an old network HUB (read about: The difference between Hubs, Switches, and Routers), I decided to try a couple of spare routers, using DHCP to supply IP addresses to the computers and the network printer. Low and behold, we thought the problem was fixed, but such was not the case. The network still bombed out. Back to the original problem after trying it for some time. The problem was still the disappearing computers on the network. Funny though, the old Windows 95 computers could talk to the Dell Vostro with Windows XP operating system, but not the other way around. Also tried swapping network cables with no change in the problem. FYI, my buddy ordered the Dell Vostro with Windows XP operating system instead of Windows Vista by choice just before the holidays. It arrived a couple of days after Christmas.

I decided to call it a night. My buddy however, started digging through the documentation. Apparently when he turned off Norton Internet Security it started working much more reliably. The network was stable for a couple of hours and he thought that was it. However, after leaving it on overnight, it was discovered that the network was nonoperational again in the morning. So, the service call was still scheduled. Dell contracts out to independents in the local areas for service. The guy came out with a new motherboard and swapped it out a day latter.

Finally, everything seemed to stabilize, but we also tried a different router and setting Norton Internet Security Zones for trusted sources (the other computers' IP addresses) and everything was talking with each other.

Microsoft I figured probably had Windows Updates available for the XP system, even though it was a week old. This was indeed the case. On a dial-up modem it only took four hours to download and install!

Computer Lessons Learned

Technology is changing so fast, that even the customer service techs have trouble keeping up with the new software. The support people are not fully aware of the full spectrum of protection that Norton Internet Security software was doing on the computer from a network standpoint.

Computers are supposed to save time. Ha Ha. Think about all the problems you have had with your computers over the years. Do they really save time? I think not, but in some ways the computers have filled our times with other activities. Internet browsing, searching for products and services, comparing prices, shopping for the new car, and even to the point of replacing TV for online videos.

Just like anything purchased anymore, the customer needs to become more of an expert and pay particular close attention to details.

By-the-way: Networking Mac OS X and Windows XP and Windows 2000

I decided that I would hook up a Windows XP, Windows 2000, and Mac OS X computers that I had together. Took a bit of research online about sharing between the software platforms, but after finding out how to do the settings, everything seemed to function. For advice on how to: Networking Mac and PC, do a Google Search. Good information is available online.

Comcast Modem Chat Session

Comcast eSupport Chat Transcript

James > Can I hook up another extra modem on my current system, by just getting an extra IP address and calling my extra modem number into Comcast central?

Allan > Hello James, Thank you for contacting Comcast Live Chat Support. My name is Allan. Please give me one moment to review your information.

Allan > No, you would need to have a second subscription to the Internet service.

Allan > Which would double your monthly rate.

James > Are you sure of this? Because when I talked to the the install guy last year, I thought he said I could do that.

Allan > Yes, I am sure. If you would like to have a second cable modem, you would need to contact our Sales department, and have them create a "second house key", which will allow a second cable modem to connect. This will result in a second charge for the internet service.

Allan > If you simply want to get a second computer connected to the internet, you could set up a home network.

James > OK thanks for that info. What then does other dynamic IP addresses do for you?

Allan > You can use a hub, switch, or router. Use of a hub or switch will require to you purchase a second IP address from us, which is $4.95 per month.

Allan > A properly configured router will not require an additional IP address.

Allan > The additional IP address allows additional computers to get online, when using a hub or switch.

James > I understand that from a router standpoint that I don't need additional IP addresses. So, what is the reason to have more than one IP address? Is it possibly for gaming? When two people want to be hooked up but with unique IP addresses from the same location?

Allan > The Comcast service comes with a single IP address. When your computer is connected directly to the cable modem, that IP address is assigned to the computer. When you have a router connected to the cable modem, the router will receive that IP address, and then the router will assign separate IP addresses to the computers connected to the router. A Hub and a Switch do not have the ability to assign IP addresses. So when you have a hub/switch connected to the cable modem, the single IP address that Comcast provides will allow one computer to get online. You would need to get a second IP address for the second computer.

James > Does having an extra IP address, and hooking up the extra computer through the hub or switch keep the speed to each computer faster than one IP address and using a router?

Allan > There is no significant difference between using a hub, switch or router.

James > OK, that answers my questions. Thanks for the help. Much appreciated.

Allan > You're most welcome.

Allan > Analyst has closed chat and left the room

Thank you Comcast for an excellent and fast response to my questions. I was very impressed with the eSupport Chat Session.

Two Comcast Modems or More at the Same Location?

How To Install Two Comcast Modems

Can I install more than one Comcast modem at one location?

The simple answer is yes, but it is going to cost you for a second connection.

The following was a submitted question to me.

Message: My wife and I have two rooms with our respective offices. Our house is new and installed with cable TV/Internet cable connections in the walls of each room. My wife's computer is connected to Comcast through a cable modem with a router. Right now I have set up a wireless connection to her computer through a wireless router in her office but the speed is diminished on my computer. The only other way to connect to Comcast through her modem would be to run an ethernet cable through the attic from her router to my office which could be dangerous.

It seems that every Comcast modem has its own unique MAC address. I do have a another Comcast modem the same as my wife's modem which I purchased on EBAY. Is it possible to clone the MAC address on my wife's Comcast Modem into a router in my office and connect the purchased Comcast modem into the cable connection in my office and be able to get on the internet? Thanks

Regards

H.

Answer: Hello H,

What I think you're asking is,

Can I hook up another Comcast modem using the front end of a router, with the cloned address of the other Comcast modem?

First off, you are right, every Comcast modem does have its own unique MAC address.

The router is meant to be on the output of the Comcast modem, not the input of the Comcast modem. Routers make the Comcast modem think that there is just one unique IP address on the output of the modem. But, in actuality, the router routs the information to each computer on the Local Area Network (LAN). The input from Comcast Central goes into the modem from the coax cable, and not the other ethernet cable for the LAN network.

I too have an extra Comcast modem. When I upgraded to digital voice with Comcast, they installed another modem with phone built-in. My original modem was purchased by me at a local store. When the service guys did the install, they had to call in the new modem to Comcast Central.

My understanding is that only one modem of that address can be installed at a time. If you think about it, this makes sense, otherwise the system would not know which modem is handling the information. However, if you want to pay for another Comcast account, I think you can get two Comcast modems hooked up at the same time but with unique MAC addresses. Gamers, who like lots of speed have done this. Comcast then splits the coax cable and runs it into both modems. Then you have two outputs (one from each modem). Note: just as your router assigns a unique IP address to each computer, the Comcast DHCP system assigns an IP address to each modem.

As far as speed is concerned with your current wireless setup, what is your Internet speed with the current setup?

Compare your speed at both computers.

How far is your wireless computer from the office router?

Certainly the best connection is to have a cable going to both computers from the router. Many times the problem with wireless is the location of the router or the location of the antennas on both the computer and the wireless router, and that they are behind shielded walls or just long distances.

So, as it is, I think you have a spare second modem that can only be used if you pay for another hook up.
