Tip & How-To about Computers & Internet

Internet Connection Basics

Modern high-speed internet connections are made using DSL or cable modems. In general, most DSL modems also act as routers, but not too many cable modems act like a router.

Some internet connection basics: Every device connected to the internet has an IP (Internet Protocol) address. The address consists of 4 groups of up to 3 numbers each. They would look like this: 123.111.36.145 (0 is the smallest number and 255 is the largest you will see). When you connect to the internet, you are assigned an IP address by your ISP (Internet Service Provider). When you hook up your computer
to the modem, the signal is passed through the device to your computer and the device's IP address becomes your address. This is not secure, as the "bad guys" could type your IP address into their machine and theoretically see your computer and access all your data.

Connecting with your modem: Modems come with a CD nowadays. Running the setup CD makes connecting quite easy. With a DSL modem, you normally have to provide a username and password to log on. Cable modems generally rely on the cable connection to your house to recognize who you are and when you run the setup CD, you are automatically connected.

The router: The purpose of this device is twofold--one is to take the signal you get from your ISP and send it to a number of computers in your home network. The second purpose is to take the IP address and send it to a different address on each computer. This acts as a "firewall" in that the IP address assigned to your computer is no longer the address of the computer. Those bad guys trying to hack into your system will have a much more difficult time.

Types of routers: There are wired routers capable only of hooking up computers with ethernet cable within a network. There are wireless routers--normally these have 4 wired ports and a set of antennas. These function will in a mixed environment of wired and wireless computers. Most people these days are using wireless routers.

In my next tip, I'll describe how you go about hooking up your new router to an existing internet connection.

I have just bought an acer iconia w3-810. When starting the set up process I can't connect to the Internet. It says I have no connection to internet. Tried setting up a network and it can't find my router which is connected and working fine. I have checked through device manager and it says network adaptor is working fine. Any ideas? I'm stuck here.


try connecting to another location like the public library. it could be that your router security setting may be set too high.

Installation speed and simplicity Installing a wireless LAN system can be fast and easy and eliminates the need to pull cables through walls and ceilings. Components of a wireless LAN To set up your Wireless network at home you need to have the following:

Access point (router)
Access points (routers) are two-way transceivers that broadcast data into the surrounding environment. Access points act as a mediator between wired and wireless network. Most routers have a built-in DSL modem that will allow you access to a high speed DSL internet connection. The ISP (Internet Service Provider) you have chosen normally supplies a modem/router with the subscription to their services. Read carefully the documentation supplied
with your Access point/router for detailed setup instructions

i can't get on the internet


>> do i have to call my internet service provider to activate my modem?

Yes.

Each modem has a unique "address", and your I.S.P. uses that address to authorize each DSL-modem that tries to connect to their network.

Or, if the two of you live in the same house/apartment, you should just buy a "router". Then, both computers can connect to the router, and the router connects to the DSL modem, and both of you can "share" the monthly fee for the _one_ Internet connection.

yes i want to find out if a cable modem will work with your dsl phone internet service?


No.

A cable-modem connects with a coax-cable to the cable-company's network, but a DSL-modem connects with telephone-cable to the telephone-company's network.

Scenario 2 to 4: Scenario 2) The modem does not have an Ethernet port. The modem is a dial-up modem for traditional dial-up service. To use the Router, you need a cable/DSL modem and high-speed Internet connection.

Scenario 3) You cannot use the DSL service to connect manually to the Internet.
After you have installed the Router, it will automatically connect to your Internet Service Provider (ISP), so you no longer need to connect manually.

Scenario 4) The DSL telephone line does not fit into the Router’s Internet port.
The Router does not replace your modem. You still need your DSL modem in order to use the Router. Connect the telephone line to the DSL modem, insert the setup CD into your computer, and then follow the on-screen instructions

for dial up simply a modem .... on laptops if you do not have a builtin modem you can purchase a pc-card modem that goes into your pcmcia slot ... for highspeed either a ethernet (same option as modem) but almost all modern laptops have a built in ethernet ... or usb ... also I highly recommend a router if you are going highspeed ... even if you only have one computer ... a router will protect your system because it provides a NAT firewall. If you go with a router make sure to set up the internet connection on the router do not tunnel through the router with a PPPoE connection
