Networking 3 laptops need help


I have been asked to buy and set up a network for 3 laptops i do not have information of the capabilities of the laptops yet but i will get more information soon.

I just need basic information on what a network includes and what components i need i am interested in using a wireless network as i have heard that it is about the same price as a cabled network would be. So the things i need information on are the following:

-Components needed

-How the components are connected and set up

Any other security information and other details i may need to know.

I am currently reading this guide thats someone gave me it clears up some thing so far but any information would still be greatly appreciated.

You could do a WiFi Ad-hoc network, All you'd need for that is three Wireless NICs at 25-30 a peice for a cheap one. Windows XP SP2 has a nice little utility for doing these.

However Ad-Hoc sucks, I would recommend getting a Access Point too, These start at about $60

Definately use an AP if security is an issue.

Will this be on the internet?

If so, AP goes to the modem with the account info entered (username, DNS, IP, gateway, etc. if not DHCP). Encryption type (WEP/WPA), channel, and NSID/SSID , et. al will also be configured in the AP.

On the laptops, you will configure them for the encryption type specified in the AP and enter the bit-key code (depending on if it's 40, 64, 104, or 128-bits) you made on the AP for each client. Set the channel for each to the same as the AP (may need to play with these if any wireless phones or microwaves are in the area depending on the band the AP and cards use, they can cause interference) and each should find the NSID/SSID when doing a scan for usable networks, or you can just enter the name you assigned to the network in the AP.

It's really quite simple if I confused you. It's basically the same as a wired network, just a few more things need to be assigned other than IP addresses.

Make sure you turn off the SSID broadcast so you don't have your neighbors snooping on your network. Use an AP as mentioned above. A "G" speed router is a preferable type as it's faster but beware the SUPER G wireless network setups. Don't buy them. Enough said. You should try and keep the network consistent. If you have all B wireless cards, stick to the B with the access point.

from what i understand ive put together parts im thinking of buying.

Wireless Access Point-

Linksys WAP54G Wireless-G Access Point (NW-001-LS)
The Linksys Wireless-G Access Point lets you connect Wireless-G or Wireless-B devices to the network. Since both standards are built in, you can protect your investment in existing 802.11b infrastructure, and migrate your network clients to the new screaming fast Wireless-G standard as your needs grow.

- Set up a high-speed Wireless-G (draft 802.11g) network in your home or office
- Data rates up to 54Mbps -- 5 times faster than Wireless-B (802.11b)
- Also interoperates with Wireless-B networks (at 11Mbps)
- Advanced wireless security with 128-bit WEP encryption and MAC filtering


Router-

Linksys WRT54G Wireless-G Broadband Router/4-Port Switch (NW-000-LS)
The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G or Wireless-B devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices. Connect four PCs directly, or daisy-chain out to more hubs and switches to create as big a network as you need. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection.

- All-in-one Internet-sharing Router, 4-port Switch, and Wireless-G (draft 802.11g) Access Point
- Wireless data rates up to 54Mbps -- 5 times faster than Wireless-B (802.11b)
- Shares a single Internet connection and other resources with Ethernet wired and Wireless-G clients
- Advanced wireless security with 128-bit WEP encryption, MAC or IP address filtering

NIC's-

Linksys WPC54GS Wireless-G Notebook Adapter with SpeedBooster (NW-011-LS)
The Wireless-G Notebook Adapter with SpeedBooster incorporates the next generation of Wireless-G. In standard Wireless-G (802.11g) mode, the Notebook Adapter can connect to wireless networks at an incredible 54Mbps. With our new SpeedBooster technology enabled, your "real-world" wireless network performance increases by up to 35%! Unlike other speed-enhancing technologies, SpeedBooster is 802.11 compliant, fully compatible with standard Wireless-G, and a "good neighbor" to other wireless devices and technologies, using a single 2.4GHz channel as specified by the official wireless standard. And, unlike other technologies, with SpeedBooster you'll see an overall speed improvement even when running a mixed network of SpeedBooster and regular Wireless-G devices.

- High-speed Wireless-G networking with SpeedBooster performance enhancement
- New SpeedBooster technology increases performance by up to 35%
- Compatible with standard Wireless-G and Wireless-B networks
- Wireless communications secured with up to 128-bit encryption

Ad-Hoc is where you have a WiFi network without a Access Point (AP) the cards talk to each other without having to go Via a central box like they do with an AP

Here's What you need:

One Wireless Router (These have APs built into them its an all in one box)
A Wireless NIC for each Computer.

You do not need an Access Point and a Router

I have also seen many different types of nic's i dont understand what the differences are.

Just make sure you get a router with a built in DSL Modem.

.

11mb
54mb and

11Mbit(2.4ghz) = "B"
54Mbit(2.4ghz) = "G"
54Mbit(5ghz) = "A"
108Mbit(2.4ghz) = "Super-G" (Read about this later on)

Quote:

There are two Frequencies 2.4Ghz and 5Ghz. Now 2.4Ghz has been a Unlicenced frequency for quite some time now so many things use it, for example Cord-less telephones. All these devices can sometimes cause interference, so thats why the new 5Ghz frequency has been unlicenced, however 5Ghz Isn't as good range and is usually only used for spefici purposes, 95% of people use a 2.4Ghz product


Note: 108Mbit (Super-G) This is not an offical WiFi standard, Wi-Fi was invented to make sure that all Wireless products work together with each other, so that you didnt need to have cisco cards to go with Cisco Access points etc. But this "Super-G" is not a WiFi Standard, so your suck with one brand, this goes agains the whole ethos of WiFi so this is why you should NOT use 108Mbit Wireless

My friend has a d-link wireless router/acess point and it seems to work quite well. of course I dont really have any experience with any other brands so I dont have anything to compare it to.

You'd be safe with either of them. I'm a little partial to NetGear products, but only because I've used them longer. I've had plenty of D-Link products too, though. I'd just shop for what I'm looking for then go with whichever brand can give it to you for the least amount of cash.
