How do I build a homemade wi-fi antenna?

I read on slashdot.org you can make one with a pringles can, but I think you have to put it on the transmitter and point it towards your computer, not from your computer to the transmitter.\n\ngoogle "pringles can antenna"  or check on slashdot.

I have done tech support for some good-sized companies, and you'd be surprised how many people fail to turn on the wireless antenna in their laptops!  SOMEWHERE on that machine you'll find a switch; if you don't already know where it is, look up the machine's spec's online.  As to finding locations - try http://www.wi-fihotspotlist.com/

Design your own!  Go to any electronics store and you can customize one with some software.  This is our opportunity to be creative.

I think Radio Shack has a kit that you make a simple radio i think  it's called a crystal radio. EAsy to build and good project.

you can use a wireless router and or a regular router and use  cables to connect them

do a project in radio transmission ..........parts for this project r fairly cheap and easy to do.........

want cheap?  Try the loacte wirless seach tool that comes w/ your comp.\n\nIt will locate any in the area and display signal strength.  \n\nCheap is free and free is....well you arn't paying for it someone else is lol.

See if your radio will take an external antenna.  If so, then grab some wire and string it around, and as high as you can.

Check the chip parameters from a databook or online at texas instruments website.To make a transmitter you have to add a mixer which takes the wave input and transmits it over an antenna.A mixer can be made by a simple high freq transistor incommon emitter mode with proper biasing....input will be through the "base" and local oscillator output should be attached to the emitter side.The output will be across emitter and collector.You should attach 2 inputs one the wave and other local signal oscillator.the output which you will get will be amplitude modulated or any other modulation scheme which you choose to implement. you should have specified if it is a analog or digital type.If u want some designing help.contact me at....joe_metallica_in@yahoo.com

download sun wireless SDK. There is a demo to show how you do it.

http://educate-yourself.org/fe/fejoewatercell.shtml\nI'm unsure of anything that describes how to really make one.\nThis site tries, but it's rather goofy to follow. Maybe you'll have better luck that I would.

Free:  Put your access point in a higher, clearer location.  Away from walls.  Move it to the very center of where you will be accessing it from.\n\nCost: go buy an antenna, or get a more powerful router/access point.  Upgrade to N technology.  This is a bit newer than G and goes farther.

Your question is a bit obscure, but I'll have at it. \n\n=====\nWireless \n\nI'm presuming your laptop does not have WiFi builtin. It can be connected to the Internet through an Ethernet port or a USB port or ... if you have the right equipment. For instance, you can buy a USN WiFi adapter (most look a good bit like a thumb drive) whcih will connect to any access point it can reach. If it's not access protected, this might be enouhg. \n\nOr you can use Ethernet to connect to a WiFi radio, use that to connect to an Access Point and proceed. \n\nin either case, there will be issues about configuring your system for a network connection on USB or Ethernet. Usually, the installation utility for the USB WiFi adapter or the Ethernet adapter, should do this for you, especially if you're using Windows as it's the most popular opeating system by far. If you're using Linux or one of the Mac operating systems, your harware maker might not support Linux. And it's possible the Linux mavens haven't yet gotten around to reverse engineering that particular piece of hardware and making a Linux driver for it. \n\n\nNow let's consider the case of a wireless router. Your laptop connects to it via Ethernet cable. Assume that's a good connection. your next question will be how to connect to a WiFi network within reach. Will it work?\n\n802.11 a/b/g/n all allow several kinds of connections. The client mode can connect to an access point, an access point can connect to several clients (typically 3 or 4, except for odd antenna arrangements), or one client can connect to one other client. \n\nIf your router is set up as an 'access point', it can only connect (except in rare cases) to a client, and can't ask the client to connect. If your router is set to 'client mode', it can ask any reachable access point to allow a connection. Access points broadcast beason signals telling clients who and what they are (unless the beason is defeated in some security modes, in which case the client wanting to connect must know the access point's information). \n\n=====\nDSL\n\nIf your laptop is connected to the router via Ethernet, and the DSL adapter is connected to the router via Ethernet, and both connections are suited to the ports (speed, duplex, crossover/no crossover, ...), you are likely to have success. You will probably have to know the IP addresses of the devices, and properly configure them, but that should be enough. \n\nThe router should have a way to defeat the wireless radio in it, as you may not want others to connect to the Internet via the router. Check the router documentatin for its control interface where this sort of thing should be covered.\n\nIf you want to use the router to provide a wireless connection to the Ethernet connected to the Internet (via  DSL), you should need only to make sure the router is in access point mode, and the radio enabled. If you don't require encryption for connecting clients, anyone who can hear the router's wireless beason breadcast should be able to use the DSL Internet connection.\n\nBut, there is considerable variation in the configuration methods and flexibility between routers from various vendors. You should certainly read the manual(s) and check the vendors' Web sites for additional material.

If the antenna is mounted the best way is to use a plumbob and a bubble level gauge. Or just the bubble level gauge with degree increments labeled. another way is to use a compass and a square against the front of the antenna. Hope this helps.

Most likely this is as a result of signal dispersal. Two ways to go with this: 1.) focus the signal coming out of your wireless access point; or 2.) attach external antenna to your wireless device (laptop, desktop, etc.). I guess you could do both, which technically is a 3rd option, too. First, make sure your access point is as centrally located as possible. If that doesn't do the trick, next I would attach a parabolic reflector to your AP's antenna(s). You can make a parabolic reflector yourself following the instructions here: http://www.freeantennas.com/projects/template/ .  Using this template, I made one out of an empty cereal box in about 10 minutes, and it worked *very* well. If the parabolic reflector doesn't do the trick, then you're pretty much left with attaching an external antenna to your wifi card. The easiest thing it to get a card with an external antenna port (Orinoco Gold, Dell TrueMobile, Avaya, etc.). Again, you can make your own antenna with a tin can and some parts that you can pick up at Radio Shack for a few dollars. This is a bit more complicated than the parabolic reflector, but I made mine in about 30 minutes. Or you can buy a pre-made antenna someplace like http://www.cantenna.com.

To boost the signal of your wireless router I would recommend buying a suitable enhanced antenna from your local computer store. They are designed to work with your router. There are also signal boosting devices that can be used throughout your home/office to help increase your signal coverage and wipe out dead spots.\n\nAs for the Sat dish; if you want to be Dr. Frankenstein and experiment you can go to your local Radio Shack and get the proper adapters to convert the connection from one to the other. Not sure if they will have the proper adapter for the router though. You may have to improvise. Will you succeed? I am very doubtful. Sat dishes are used to RECEIVE SIGNALS, not TRANSMIT! You may get better luck just using the coax cable used with the dish. But then again, stranger things have happened...

Turn on the WiFi antenna switch, usually on the right side toward the back and you'll see a orange light come on. Then open your network connections and enable your wireless connection. First you need to view all wireless connections within range and choose  the wireless connection you want to use. If there are no wireless connections within range your computer won't work wireless. Unless you get a router and make your own wireless connection.
