You need to enable your WEP security feature in your WiFi Access Point. \n\nDepending on the brand you are using, there are different methods of accomplishing this task.\n\nOnce you have enabled WEP security, you will be generated a "key" to give to those other people whom you want to access your access point. This will prevent those unwanted bandwidth leeches from accessing your internet bandwidth.

You need a card which supports 802.11G (it's backward compatible with the older and slower standards which are 802.11A and B). \nI just bought one from Linksys, it works fine. I would not recommend those fancy new cards with reconfigurables antennas and double bandwidth, I didn't find it worth the extra bucks.

I would suggest a solution of Wireless LAN Bridging (WiFi) ... It would be very effective in 1 Km distance it would give throughput of 24-36 Mbps which is quite enough for most applications. check Cisco, D-Link , and USrobotics devices and solutions.

I have had the best distance results with the D-Link DI-784 -- it supports both 802.11b and 802.11g, and one of the two should be detectable by your wireless device.\n\nYou should know, however, that if you're talking about cinderblock walls, you don't stand a chance -- they kill the signal completely.

no if you can connect via wifi it is free. there is no FCC law saying that you have to pay for a unprotected wifi access point\n\nso have fun, and on the net you can find maps of free wifi points\n\nand the owner can only see that another computer is on his network only if the owner knows how to run the frameware

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.

Check out http://www.mikrotik.com/ they have some nice outdoor access points and also some with two wireless cards so you can do repeating also.\n\nFor the clients I would suggest http://www.tranzeo.com\nThey have some kick but wireless radios.\nI have personally used the TR-CPQ-19f for site surveys and they work really well.

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.

You're probably going to be limited to line of sight inside the mobile.. You could add repeaters, but it's probably not worth the cost.

wireless like psp or a pda? did you set the software in your pc for being a host pc ?here some help.\nUnderstanding the Basics \n\nIf you're thinking about building a wireless network for your home or office, it pays to do a little planning to ensuree you implement it as securely as possible. Remember how you listened to your next-door neighbor's conversation with her mother-in-law about what happened at last year's 4th of July party on your baby monitor? Like all radio frequencies, anyone with a receiver can tune into a wireless channel, so you need to take extra precautions to prevent to your big-eared neighbor and cybercriminals from listening in. \n\nThe primary reason for building a wireless LAN (WLAN) is for increased mobility — so you can move around from room to room without being tethered to a network jack. Another reason people like wireless LANs is because they can network their computers together without having to snake wires through their walls. Since you don't have to deal with the wires, in some regards building a wireless LAN is actually easier than you might think. \n\nHave questions about wireless? Start a thread in the new Intranet Journal Discussion Forum \n\n\nThere are all different kinds of wireless protocols used for different types of wireless networks, but if you want to build a WLAN for your home or office the type of protocol you'll want to use is called 802.11b. When you build a wireless network, you are basically setting up a transmitter called an access point that has an antenna on one side and a wire on the other. The wire plugs into a typical wired connection — an Ethernet, a DSL line, cable connection, or dial-up modem. The antenna talks to the wireless network interface card on your computer, sending network traffic from your laptop to an access point. If it sounds confusing, think of your cordless phone. On one end your cordless phone plugs into a wire, while at the same time the antenna on the hand-held receiver transmits to the base station where the wire is plugged in. \n\nSet Up Your Access Point \n\nOne of the first things you'll need to do is setup a wireless access point (AP). If you're setting up your wireless network for a business, you'll want to use a more fully featured high-end AP like a Cisco Aironet 350 Series access point. If you're setting up an access point for a home network, a low-end access point such as a Linksys WAP 11 or an Apple AirPort will suffice. Any access point worth its salt has a TCP/IP interface whether you are setting it up for your home or office, which is something to keep in mind when making your purchasing decisions. \n\nWhen setting up your access point, you'll want to first connect it to the wired hub, then configure the wireless interface, then the wired interface, and last but not least, configure the security. Configuration of the various network interfaces and access point features is different for every vendor. However, if you can read and follow directions, it's possible to do the installation yourself, even if you don't have prior experience. Just open the access point installation and configuration guide and follow along. If you run into snags call the vendor support line list in your access point manual and ask for help. The types of things you'll need to setup include the radio frequency, the distance between access points, and the access point IP address. \n\nSome of the features you can expect to find in either home or enterprise class access points are listed in this table: \n\nFeature Small Office/Home Office Large Office \nIEEE 802.11b compliance   \nDHCP Server   \nNetwork Address Translation   \nIPSec Pass Through   \nIAPP \n  \nSite Management Tools \n  \nWEP (Security)   \nTKIP (Security) \n  \n\n\nYou can also use what is known as a wireless station instead of an access point. However, wireless stations may take a bit more work to setup, and I won't be talking about them f

If you're not getting strong enough signal to your Wireless USB you might want to look into a 802.11g Range Extender. Because it's a powered unit it has the power to pull signal in from further distances and then repeats it out to the area around it.\nI have one and it works like a charm for extending my network. I've given you links below for the types of devices I'm talking about. You can pick them up at CompUSA stores here in the states and at other stores locally. They run between $80 and $100 USD

Access Points run at the same radio frequency as many other household items (Cordless Phones are the most common.)  You might be getting some interference with other APs or other wireless devices.  My guess will be your neighbor's AP is on the same channel as yours.  Try changing the channel on your AP.  Check your APs manufactures website to get instructions on how to change the channel.

You should scan the airwaves for competing access points. If you can find a free channel, then use that channel for that access point. If at all possible try to be at least 5 channels away from the strongest signals. You can also consider going with an A type network which uses different frequencies than the b/g networks. The cost is somewhat higher, but worth it if congested airwaves are an issue. You can also consider using directional antennas on your adapters in order to "mute" the competing channels.

YOU make it up, store it on the access point (or wireless router) then use the same one on your wireless cards.

you should be fine with that kind of signal... make sure the laptop network settings is set to dhcp, also make sure you do not have an access control list setup on the wireless (like only certain MAC addresses can connect)\nIt does not have to be matching equipment though it usually works better that way. And when trying to boost the signal you normally put an amplifier on the access point and a higher gain antenna on the wireless card
