What the differenc between 802.11b  &  802.11g wireless adapetr?
483315
The only difference is the speed.  b does 11Mbps while g does 54Mbps.  They both operate on the same frequency and are compatible with each other.

look for 802.11g routers they are faster than 802.11b. look for one with long range it might be useful. Usually the more antennas the bigger the range.

Are you saying that the laptop does not already have a wireless card in it.  Most new laptops sold are already equipped with 802.11g (aka 54g) wireless cards.  I would check your manual or specs to make sure that it doesn't already have a card in it.  If it doesn't read on.\n\nIf you want to use WiFi in your home then you will need a router.  My personal favorite is anything by Netgear but any basic WiFi router should serve your needs.\n\nAs I said above if your laptop doesn't already have a WiFi card, then you will need to get a PCMCIA or USB wireless adapter.\n\nI would bet though, that the new laptop does already have a WiFi adapter in it.

I'll answer the question generally, since individual products may, as you suggest do a little looking around without telling you. You might want to watch the activity lights when you connect, and try to correlate them with the connection sequence. \n\nI'm assuming here that you have the commonest sort of arrangement, a router (connected to DSL, cable ? etc) and a laptop with a wireless client radio inside. \n\nEvery 'access point' (one type of radio operating mode) must broadcast a beacon signal to tell possible client radios in range something about itself. For 802.11 b/g (and probably n, but I haven't checked) the beacon is broadcast on the only channel that is legal everywhere, channel 10. It's also broadcast with the lowest possible legal speed. This means that any client 802.11 b/g radio in range will be able to hear and understand the beacon. \n\nOnce the client radio hears all the local beacons, it chooses one (usually based on signal strength) that it can interact with. So an 802.11b client radio, which knows nothing about 802.11g format signal types (ie, 'modulation schemes') won't be able to work with an 802.11g access point and both had better be willing to find the highest performance connection possible to both, in this case one of the 802.11b schemes, and not any of the 802.11g expanded schemes. \n\nThis takes a bit of time. but once both ends have discovered the highest performance configuration they can both support, the radios can actually tell the software (drives, operating system, ...) what's going one. At that point, Ip addresses have to be assigned to allow any traffic to and from the Net. If the Operating system is configured to use DHCP, it must contact the DHCP server it's been told about, and 'lease' an IP address from the block of addresses the  ISP has had assigned to it. Next time on the ISP, the IP address assigned might be entirely different. Or the Internet software using the client radio might have been given a permanent IP address (called 'static' address assignment in contrast to the 'dynamic' assignment under DHCP). \n\nAll of this takes time. Which further depends on the connection scheme (speed, modulation, etc) the radios have agreed on. So a marginal 802.11b connection (distant location, poor antenna placement, bad polarization match, ...) might only be able to manage the barest minimum, 1Mbps. A really good 802.11g connection, could use the highest speed possible. which will of course never be as fast as the ads claim. there is a good deal of handshaking and  timeout settings, and error announcement sent back to the other radio when found. \n\nAnd there is a backoff_and_try_a_lower_speed_connection negotiation when there are more than x errors (varies by manufacturer default, but is sometimes changeable by the user for a particular installation in the case of some utilities and software drivers). And an occasional try_to_use_a_better_speed_ connection if we haven't had errors in the most recent y seconds. Either requires another negotiation sequence, which again takes time. \n\nAnd, if the range is marginal (almost too far away) there will not only be automatic up regulation attempts, and perhaps some down regulation attempts, but more a few entire reestablish_the_connection restarts as signal drops below the radio's sensitivity threshold (all real world equipment has them). \n\nAnd some operating systems take their own sweet time to recognize a new device (in Windows, you may have to run the add_new_hardware wizard in the control panel manually. Sometimes the whole add new hardware routine more than once to succeed.  \n\nFinally, on initial start up, most browsers depend not only on hardware initialization, connection negotiation, DHCP negotiation, and so on. But also must do a DNS lookup, and download the current versions of a 'home page' (which may be larded with images from many other sites). It can

The WiFi band is broken down as follows:\n802.11a = 5Ghz\n802.11b = 2.4Ghz\n802.11g = 2.4Ghz\n\nUnfortunatelly b & g can get serious interference from microwaves, cordless phones, Bluetooth, and other equipment using the same 2.4 GHz.\n\nIn b & g there are 14 overlaping channels or bands.  the best ones to pick are 1 and 11.  Note that they do overlap, and the channels only represent the "center" of the frequency range.  The channels are 5Mhz appart.\n\nThe most interference you will get in a building is power, microwave and cordless phones.\n\nWiFi has been demonstrated to work 150+ miles without interference on a flat surface.\n\nI included a few links for further education.

802.11 G & B routers transmit at 2.4 ghz.  802.11a routers transmit at 5 ghz.  You may be able to pick up your router signal with an old school cordless phone where you can change channels, but you won't hear anything but fuzz really.

It is wireless router standards.  They tell you at what maximum speed the router will transmit or receive data.  The highest standard is G.

You need to have a wireless a/b/g card installed and wireless internet service.

You can connect a wireless router to a DSL modem in order to accomplish this.  I've used a Netgear router successfully for this that I purchased for a steal on ebay.  If you go this route, decide between 802.11b and 802.11g by weighing cost against desired speed.  802.11b routers are cheaper and offer the same distance, but a limited speed output.  802.11g routers are a new technology and are more expensive but offer a faster connection speed to your modem, and consequently to the internet.\n\nAnother alternative if you've been a loyal customer of a service like Verizon DSL for a year or more is to ask them for one of their upgraded combo modem/routers that they've been handing out to new customers for the past year.  My father successfully accomplished this by calling and mentioning that he was growing more interested in switching to a cable internet service because of speed limitations.  They seem pretty prone to throwing technology at a potential lost customer in attempts to appease them.

Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance. \n\nAny products tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. A user with a "Wi-Fi Certified" product can use any brand of access point with any other brand of client hardware that also is certified. Typically, however, any Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b or 11g, 5GHz for 802.11a) will work with any other, even if not "Wi-Fi Certified." \n\nFormerly, the term "Wi-Fi" was used only in place of the 2.4GHz 802.11b standard, in the same way that "Ethernet" is used in place of IEEE 802.3. The Alliance expanded the generic use of the term in an attempt to stop confusion about wireless LAN interoperability.\n\n------------------------------------------------------------\n\nWi-Fi: How it works\nThe typical Wi-Fi setup contains one or more Access Points (APs) and one or more clients. An AP broadcasts its SSID (Service Set Identifier, Network name) via packets that are called beacons, which are broadcasted every 100 ms. The beacons are transmitted at 1 Mbit/s, and are relatively short and therefore are not of influence on performance. Since 1 Mbit/s is the lowest rate of Wi-Fi it assures that the client who receives the beacon can communicate at at least 1 Mbit/s. Based on the settings (i.e. the SSID), the client may decide whether to connect to an AP. Also the firmware running on the client Wi-Fi card is of influence. Say two AP's of the same SSID are in range of the client, the firmware may decide based on signal strength to which of the two AP's it will connect. The Wi-Fi standard leaves connection criteria and roaming totally open to the client. This is a strength of Wi-Fi, but also means that one wireless adapter may perform substantially better than the other. In Windows XP, there is a feature called zero configuration which makes the user show any network available and let the end user connect to it on the fly. In the future, wireless cards will be more and more controlled by the operating system. Microsoft's newest feature called SoftMAC will take over from on-board firmware. Wi-Fi transmits in the air, it has the same properties as non-switched ethernet network. Even collisions can therefore appear like in non-switched ethernet LAN's.

Very briefly, antena, radio, router, power supply, processor, firmware/software.  A little more detailed... The antenna receives and transmits RF energy.  The power supply typically converts your 120VAC and provides the needed DC power levels to the internal components.  The 802.11a/b/g radio itself consists of various sub-components such as mixers, filters, oscillators, detectors and the electronics that connect them all.  The router processor consists of whatever router chipset is in use and implements TCP/IP and Ethernet.  There will also be some on-board flash (for saving image and config) and DRAM.  There will also be firmware/drivers for the 10/100 RJ45 physical interface for example.  There is also other firmware/software that gets loaded such as a management interface so you can configure it.  There may also be an internal POST component for bootup diagnostics.
