Is There Truth To This?

Sun Mar 14, 2004 3:36 pm

Trying to clarifywhat was said to me by an associate today.

Let's say you have a computer in your house and you pay fee "A" for internet access.

Then you buy 3 more computers and a router. So you have 4 computers through the router getting internet access.

Is that illegal to have the router and pay for the access 4 for 1?
Or do you have have to pay fee "A" and plus a bit more?

I don't think it is illegal.

It might breech your contract with your internet provider.

Check the fine print.

I'm no computer 'expert', but wouldn't splitting your internet cable that was intended for 1 computer and routing it to 4 decrease the speed of each connection? Same as splitting your TV cable seems to decrease the quality of the picture on each TV that it is connected to?

More splits(cable) = Worse picture
More splits (internet) = Slower internet?

Am I right about this? Or am I way out in left field? Big grin

Most ISP's will include 2 or 3 IP addresses with your service. So 2 or 3 computers on the same connection. Let's say if your ISP gives you 2 IP's then you can have 2 computers on the same connection using a hub. If you wanted to put 3 computers on it (with only 2 IP's) then you'd need a router. I'm not positive but I think the router uses one of the IP's so you can have how ever many computers the router can handle using the same IP for an internet connection.

I'm pretty sure it's not illegal, but you will not get any tech support for any computers that aren't on the IP's provided by the ISP.

Some ISPs even give instructions in their homepage on how to set-up a home network.
So, to answer your question -
1. It's not illegal.
2. Fees would depend on the ISP. But, I suspect not many charge extra these days.

In the UK, you pay for one TV licence but you can have as many TVs in your own home as you like. So I'd be surprised if there's a problem with the Internet going the same way.

OK, so while I reboot my entire system, ROUGH FRIGGIN WEEKEND....
lost al my files, etc,

anyway, My computer is plugged into the router in my brothers room. So I guess Optoline doesn;t care how many computers are plugged into the router.

A TV license in the UK costs about £120 a year, and its to fund the BBC channels because they don't rely on adverts (commercials). Every house with a TV or equipment that can pick up BBC channels must have a TV license.

If you´re going through a router, the ISP can´t really tell if you´ve got one or more computers connected. The only thing is that you might be in breach of your contract, if it precludes a multiple-system setup (as it does or at least did with german T-Online in certain cases).

No, it is not illegal. A router works by taking your broadband connection and routing it to all of the computers connected to the router. The router itself takes the IP that your ISP assigns, and then each computer is given a new IP address on the LAN, but that is not accessible to the outside internet. Any computer surfing the net through the router will be seen as the router's IP. So essentially, all of the computers on the network are working under one IP.

I have 3 computers conected by a hub, and when I have problems, I get technical support. So i don't think it's illegal!

TV License;
It's like a driver's license, but for TV.
You take a little test, they give you a remote control...
If you don't abuse your privileges you get to keep your license  Big grin

It is not "illegal" (ie stealing) to connect multiple computers to a single internet connection (it is called Internet Connection Sharing, and is built into windows as of windows95SE)

Certain ISPs may however decide that it is against the terms and conditions. The problem is its impossible to tell if you have more than one computer there or not.

You do not necessarily need a router to share an internet connection, all you need is a PC with a modem and a network card. Simply connect the PC to a network (either to a switch/hub/router/direct to another pc) and right click on the internet connection, and select "Internet Connection Sharing". Any PC on the network will be able to access the internet provided the host pc is connected to the internet.

As someone mentioned earlier, splitting the connection simply shares the bandwidth. If only one PC is using the internet at a time it will use the full bandwidth (say, 1mb). If two PCs try to use the PC at exactly the same time the bandwidth will be divided up between them, depending on how much they need. If both PCs are downloading huge files the bandwidth will be split 50%, but if one is downloading and the other is just browsing A.net forums the split will probably be 90% to the downloading machine..

No matter how you are connected (router or PC) from the outside it will appear as if there was only one PC on the end of the connection (a router would appear as if it was a PC). This is why Routers can be far more secure than a normal DSL modem. With a dsl modem anyone can communicate directly with the PC and try and hack in. With a router they hit the router and think its a computer. They then try their usual tricks but wont get very far cause it isnt a PC they are talking to!

Correct... A software router will do the trick just as well.

OK, time for a little Internet 101 here.

Both DSL and Cable Modem service assign a single IP address to whatever device is connected to the line coming in off the street. The IP address is the fundamental unit of addressing in computer networking. Think of it as your "phone number" when you are attached to the internet. There are two ways of having an IP address assigned to your computer, Static or Dynamic.

If an address is assigned via the static method, it means that you are given a specific number to key into the configuration of your network connection. This is seldom used any more. This address stays the same until you change it.

A dynamic address is a address that is assigned to your computer when it connects to the network. It can change every time you connect, although it does not have to. The address is assigned for a limited period of time. It is called leasing in the industry. This method is the most commonly used method.

Now when you are connected directly by DSL or Cable to your Internet Service Provider (ISP), you can be assigned an address either way. If you want to put multiple computers on the connection, you would then connect a router to the ISP-side connection. Think of the router as having a ISP side, and a "house" side. The house side is the side that you connect the computer(s) in your house to. The ISP side of he router is the side that connects your DSL or Cable modem .

Wires From Street<--->DSL or Cable Modem<-->router<-->computer

The router is given the IP address your provider assigns to you. The router will then dynamically (on its own) assign IP addresses to each of the computers on your network in your house. Some routers today come with a hub or switch (splitter type technology for networks) built in, in other cases you will have the hub or switch connected to the house side of you router. The router will use only one IP address when communicating with the Internet, and then will coordinate sending the correct information to the correct computers inside your house.

The speed of your connection to the internet is measured as it enters and leaves your house. If you have a 1 megabit connection, that connection is shared across the number of computers you have in your house. You do not get more speed (bandwidth) because you have more computers. The bottom line is that most ISP's don't really care if you have 1 or 100 computers on the house side of your connection, all the computers will share whatever bandwidth you paying for.

I started out with one computer on my connection when I got it three years ago. I am now up to five. For most "surfing", the sharing is not really an issue. However, if one or more of the computers on the network are uploading or downloading large files, all of the other computers will suffer from slow response times.

Words of caution; Do not think that putting a router in front of your PC's protects you from hacking. Some of the newer tools that are available allow hackers to get past the router. There are also methods of using Instant Messagener to gain access to your computer. A router plus firewall software is the best protection you can get, along with good virus software There are a number of providers out there. The most well known commercial products out there are Norton AntiVirus and Norton Personal Firewall. There are others. Even if you only have one computer, it is worth your while to put in a router along with the protection software. If you value your computer AND your data, it can be the best investment you can make.
