Tip & How-To about Computers & Internet

How does Wireless Network work?

A wireless network is simply two or more computers linked together by invisible radio waves with the purpose of transferring data or sharing resources. The configuration is similar to cordless phones in that they can share one telephone line, which utilizes one central "base" station along with multiple handsets placed throughout the house. Wireless networking is an excellent solution because you don't have to deal with cables and it takes little effort to expand.
There are two kinds of wireless networks:
Ad-hoc mode: Each computer in the network with a wireless adapter can communicate directly with each other without the use of a router or access point. You can share files and printers with this method. However, it is more difficult to connect to networks - both wired and wireless. This mode is also known as peer-to-peer networking.
Infrastructure mode: Each computer in the network uses a router or access point to handle all data transfer and network traffic. You can easily access a wired network, whether it is a LAN or the Internet. For most home networking purposes, infrastructure mode is the best choice.

Wireless Standards
Wireless-B (802.11b) - Operates on the 2.4GHz frequency band and can transmit data at speeds of up to 11Mbps within a range of up to 100-150 feet. Wireless range can be affected by reflective or signal-blocking obstacles, such as mirrors, walls, devices and location, whether indoors or outdoors.
Wireless-A (802.11a) - Operates at the frequency of 5GHz, which is less crowded than 2.4GHz where telephones and microwaves may cause interference. Although the speed is up to 54Mbps, the range is only up to 75 feet. Wireless-A is incompatible with both Wireless-B and G because it operates at a different frequency.
Wireless-A+G (802.11a + g) - Linksys also offers dual-band products, in which routers and adapters are compatible with both 2.4GHz and 5GHz frequencies. Both radio bands work simultaneously, blanketing your wireless zone and bandwidth.
Wireless-G (802.11g) - Features the same benefits as Wireless-B, but offers 5X the speed at up to 54Mbps. Wireless-G currently offers the best combination of performance and value. You can mix Wireless-B with Wireless-G equipment, but you will lose the higher performance speeds of Wireless-G.
The chart below outlines the differences and features for each wireless standard, along with the activities that are best suited for each one.



Network Hardware
Once you've chosen the type of network (wired or wireless) for your home, here is the basic network hardware that you'll need:
Router: This is considered the heart of your network and is the device that routes all the traffic to and from the Internet to the various computers on your network. It lets you share files and printers, and provides a basic layer of security from Internet threats.

High-speed Internet Connection (either DSL or cable): You can purchase High-speed Internet service from your local telephone (for DSL) or cable company. Both types of connections are considerably faster than dial-up access. High-speed Internet is also commonly referred to as broadband.
Modem: Connects your Internet service to your computer so you can surf the Internet and access your e-mail. Depending upon what type of broadband service you have, you must purchase or rent either a DSL or cable modem. Or, you can purchase a modem from your local electronics retailer or e-retail store. Linksys offers a gateway router which is an all-in-one solution that combines the functions of a router with a cable or DSL modem so that two separate devices are not required.
Network Adapter: Allows your computers to connect to the network. If you already have a wireless or network adapter pre-installed in your computer, you may not need to purchase one. There are different types of adapters available, depending on if you have a desktop or laptop computer.

For a Desktop Computer:

  1. A PCI Adapter - connects inside your computer, requiring you to remove the outside case.
  2. A USB Adapter - does not require you to remove the outside case since it simply plugs into a USB port on the outside of your computer.

For a Laptop Computer:
  1. A PC (PCMCIA) Card - about the size of a credit card and simply slides into a slot on your laptop computer. This type of card is recommended when using a wireless network setup since you can walk around without having to juggle an external adapter.
  2. A USB Adapter - simply plugs into a USB port on the outside of your laptop computer.
How Routers Work ?
The Router is the central component in connecting all of your computers and network devices together, allowing them to access and share one high-speed Internet connection. It organizes all of the devices in the home network so that they can communicate with each other and share information. A Router combines the functions of a switch, which organizes and controls data flow among your computers and network devices. A switch is best for wired networks that want to share files and printers, but does not provide Internet access capability.
A Router joins two networks, your home network and the Internet, passing information from one to the other. It also determines how the information is passed in the most efficient manner. The router's two main jobs are:
  • To make sure that information doesn't travel where it's not needed.
  • To make sure that information travels to its intended destination.
The Router also provides security measures to your network which prevent outside users from accessing your private data. This is important because a high-speed Internet connection is always on, which makes it more vulnerable to attacks from hackers. You may already have a basic software firewall installed on your computer, but the network can still be easily broken into.

Short wave radio connections


Probably use different frequencies if you mean by "get output from shortwave radio" that you are getting output via a receiver in the computers.

If you mean, on the other hand, that some program is taking the output from Radio 1 and it's showing up on Computer 2 then it may be that it isn't on Computer 2 but that a folder on Computer 1 is showing up on Computer 2 and you are looking there thinking you are looking at a folder on Computer 2. On a network there can be "public" folders that reside on one computer but can appear on another as if they were "local" to that computer. So the problem may be that the input from Radio 2 is coming into Computer 2 but that when you look for it, you are looking for the "shared" folder from Computer 1 rather than the folder on Computer 2 where the incoming stuff is being stored.

To solve this the first thing I would do is unplug the network cable and see if you are still receiving updated information from Radio 1 on Computer 2. If not, and the data from Radio 1 is being updated on Computer 1, then you know you are looking on a shared folder of Computer 1 and thinking it's the folder for Computer 2 where the Radio 2 information is being stored. But it's not. Look carefully, and if Radio 2 is being received, it's probably being put somewhere else on Computer 2. Unplugging the network cable just insures that the "Radio data" folder on Computer 2, the one you are looking at and seeing Radio 1 data from" is, in fact, the folder from Radio 1. And you know that it is because if Computer 1 is receiving data from Radio 1 and that folder is not being updated (which it can't be if it's disconnected) but does get updated once you put the network cable back it.

Finally, you can also test Radio 2 to Computer 2 connection by simply turning off Radio 1. If the folder you think is receiving Radio 2 continues to update, then it is Radio 2. If not, then it's probably a Radio 1 folder "shared" from Computer 1.

Good luck.

We have 2 Acer laptops. The screen on one is broken. Can we coonect the two by a USB cable so that we can transferr files from the broken laptop to the good one?


The bset way to do this is to have a switch or router, and connect them by network and transfer all your needed files.
chiefmecha.jpg
the only problem you might have is, file sharing, meaning if the files you want is readily shared, but there is a way to do that. First try to borrow a montor or LCD screen and connect to the broken-screened LAptop, and try to share the files to network.
One more easier way to fo this is to install a monitor on the broken-screend one, install a USB external hard drive on it and then copy all the files you want. After copying thet, install the USB Hard drive on your perfectly working laptop and copy the files. This procedure is more easier than what you have in mind, cheaper too, because you can always just borrow a USB Hard drive or flash drive. Even a small capacity flash drive would do, it just takes more times of plug and unplug because of the capacity issue.
Hope this helps and Thank You for using Fixya.

How to connect a DSi to your PC?


Well, you can transfer files by copying them to/from an SD card. You may be able to connect to your PC via an wireless ad-hoc network, but the only purpose of that would be to share your PC's wired internet connection with your DSi. Otherwise, they aren't really intended to network together.

how do I do file transfers from one wireless laptop on a westell 6100 dsl model to another wireless laptop on the same modem. Neither laptop in connected to the modem via eithernet. how would I set this up?


Hi There.. Please follow te below steps..

1) Connect your old computer to the wireless network. Nowadays most people use the internet through a wireless network. So basically, if you have wireless internet and you are able to get on the internet... that means you are connected.

2) Go into the networks settings. This is usually as simple as right clicking the network's icon and then clicking properties. What you want to do is turn on, "file and printer sharing" within the network

3) Now, go to the folders/data that you want to transfer. Right click or get into the properties of that folder. Check the box that says "share this folder with network".

4) On the new computer, connect to the wireless network. Under control panel or possibly the start menu, there should be an option for "My Network Places" or "My Network". In this folder you should find the data that you chose to share from your old computer. You can simply copy/paste or drag/drop the files to your new computer.

Now you are offset to transfer the files from one laptop to another...

Dwl-510 11 or 54 MBPS


MBps or megabytes per second, is your data transfer rate. This varies on signal strength, quality, interferences, etc. If you can get a little closer, great if not, try to get metal obstacles out of your way to get a little better signal. Wireless ethernet is transferred via radio waves, often metal objects can obscure the signal strength. Also try moving the antenna to a horizontal position this sometimes helps.
