What the differenc between 802.11b  &  802.11g wireless adapetr?
601163
802.11b is a global standard (a rare thing indeed!). Therefore with a multi-lateral roaming platform in place WiFi has the potential to become the de-facto standard for international remote-access wireless data services and utlimately, with VoIP, for voice too.\n\nI have 802.11b built in to my note book and do not have to have anything else except a WiFi area.\n\nthe letter after 802.11 is for the later upgraded editions.

Try looking up your router and modem on this site(make sure you include the model #, for example "linksys wireless g broadband router, etc.:\nhttp://www.dslreports.com/\nsometimes they will have the instructions on how to configure your router.

The a, b, and g concern themselves with the college's wireless network.  If I'm not mistaken, a operates at 1.0Mbps, b at 11Mbps, and g at 54Mbps.  They are all based on the wireless standard 802.11...that's why the boxes say 802.11a, 802.11b, 802.11g, or a combination of the above.  You have to talk to the college to see what type of network they have: an "a/b" card will not work on a "g" network.  But as long as you get a card with all three (a/b/g), no matter who makes it, you should still be able to get online.  Just remember to get the college's access keys and your computer named (it should be done for you automatically) on the network.

The difference is relative. Bluetooth is very short range stuff whereas Wireless connects to longer distances. Regular wireless is what you want to connect to the net when at home or at Starbucks(basically places which list as WiFi available!!), Bluetooth on the other hand is used to communicate with your personal devices like cell phones, Organizers, Printers which have a similar capability. \nIf you have a bluetooth cell phone then you can download cool stuff on it like new ring-tones, wallpapers etc without paying anyone anything(the formats change from cell phone to cell phone so just google it up and you can get a specific website!!) Try looking for Bluetooth devices on the net.

Standards.  Actually, there is a 802 standard (100BaseT4) that uses all eight wires, but it's not commonly found.

I could answer this in several ways, based on your level of technical expertise.\n\nSimply put, you need a wireless router or access point.  This will provide the "link" between your network and any wireless cards that are in your PCs.  The PCs to be attached to the network are called clients.\n\nYou can have either a Wireless B, Wireless G, or Wireless A network.  G is backward compatible with B (meaning you can, if the router is set to "mixed mode") run a Wireless B laptop in a Wireless G network ... it will just run slower.\n\nThere is also MIMO or 802.11n wireless, but this standard has NOT been ratified yet.  You can run 802.11b or g clients with it as well MIMO clients.\n\nAdditionally, it's 100% necessary to use some sort of encryption in your network.  Otherwise people will be able to monitor your network traffic and pick up passwords, account numbers, etc.  Obviously this is not likely to happen, but you can use either WEP or WPA and it's fairly painless.  Note the word fairly.\n\nI'm going to give you a bunch of links in the Sources section that will help you in more detail.

Record the number of errors.  Refresh the list of wireless networks your laptop can see -- are there many or just your router?  Then move your laptop/PC closer to your wireless router. Turn off all cell phones, baby monitors, cordless phones, microwave ovens ... did the errors decrease?  Login to your wireless router and ensure you are configured for the USA or Europe.  The USA uses channels 1-11 while Europe uses channels 1-13 for 802.11b standard with 22 MHz wide signals at 25 MHz spacing.  This an option in your wireless router and laptop to select the regional configuration.  You did not specify the operating system but if it is Windows then upgrade to SP2 -- there are know reset issues with prior software.

You have several options.  You may not need to use PC Card and decide to go with a USB solution.  In either case you will want at least an 802.11g card.  That is pretty much the de facto standard these days.  You can get a 802.11g"+" cards that promise to double the standard transfer rate of 54 mbps but it also requires that you upgrade your equipment to be able to use this extra speed.  For compatibility purposes you may want to skip this option and not pay extra for this.\n\nDo not buy a 802.11b card, as it is almost obsolete at this point, and depending on your needs you might want to opt for a MIMO WiFi card that integrate latest antennae technology to improve your speed and you range.  This of course comes at a price, and this also means that you will need to buy an MIMO capable router.\n\nYou should expect to pay around $40 dollars for a standard 802.11g card and upwards of $80 for a MIMO card.  Along with this you will also need to buy a WiFi router which will cost upto $100 dollars depending on the features you want.\n\nMost manufacturer ofter rebates so you may want to keep your eyes open for mail in rebates that will sweeten the deal.\n\nFYI 802.11n (the next generation of WiFi) standard was approved and all major wifi chipset manufacturers have announced products based on this new standard.\n\nAs for installation procedure, you should follow the manual that comes with the product step by step.  Avoid using an unknown brand name equipment for this reason.  Support and installation instructions will be sparse.

wlan= wireless LAN.  Such as wireless A, B, or G.  Commonly used for networking computers wirelessly.\n\nbluetooth is a trademarked communications protocol initially designed for wireless keyboards and mice but now most commonly used for wireless cell phone headsets.

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.

You might have to go into the configuration, IDK if you have done it yet or not because you didn't specify. But go into your internet explorer and type in http://192.168.1.1 or 192.168.1.100 and you might have to enable wireless through that. I have had that same one, I now moved to the WRTG5B or some shit. =) lol. . . You have to enable wireless, to test if your router is even working if you have an extra network cable, plug it into the router then hook it up to the laptop and see. It also could be for the fact I think that specific router is only B capable? Maybe...check your laptop to see if it is both B & G wireless ready.

Hello !\n\nThe difference between them is the frequency.\n\nCell phones use: 800, 900 or 1800 MHz or GHz[i hope I'm not wrong]\nand the\nWireless network uses: 2.4 GHZ and 5 GHZ spectrum.\n\n\n© ßogdan @ CyE CORP.

Agree with #1, and will expand.\n\nMost consumer available wireless G receivers can receive wireless B signals, but not necessarily. You need to make sure the wireless router is capable of that. Indication is usually well marked on the equipment.

There are couple of factors involved here.\n\nI do not know if you know in advance what type of wireless network you'll be connecting to or what type of wireless network you plan on creating, but this information is important.  The network maybe 802.11b network or 802.11g network (backward compatible with 802.11b) or mixture of the two.  Complicating the matter even more is the additional capabilities of the newer wifi models that support 802.11g (Turbo mode) promising speeds ~100+ megabits per second (vs. 54 mbps).  And there's also some models that use the MIMO antenna technology to increase speed and also coverage.\n\nIf these factors are unknown, you should try buy for compatibility.  My suggestion would be to buy a standard 802.11g card made by D-Link, Linksys, Netgear, or any of the other known brand names.  Any 802.11g Turbo speeds are based on proprietary technology and only work for the respective chipset.  \n\nIn my opinion, and I'm speaking as a soldier who spent time in Iraq running a wifi network, the problem is mainly of range and coverage.  It may be necessary to purchase a separate hi-gain antennae to cover the distance between the access point and the laptop.\n\nAs for a USB solution, I would not recommend a USB solution due to its size and it will be awkward sticking out of the laptop.  PC Card is the more elegant solution, UNLESS you need to use it for a desktop as well.\n\nIf you can provide more detail on what type of network this laptop will be added to then I can give you specific recommendations.

This is because it's a different, newer and more sophisticated technology.  3G is an entirely new technology on different frequencies, it's not really the "new" version after 2G.  Compare the two articles below, each is well written on 2G and 3G and discuss some differences between the two.

If the box says 802.11b or 802.11g, and especially when it has the WiFi logo, you're probably going to have an easy time making it work with anything.\n\nIf it says things like "double speed" or "range extender" or "one touch setup" you're going to have an easier time if you buy everything from the same vendor.\n\nWiMax is a new standard that was originally designed for ISPs.  (You get a "wireless" box in your home, but it doesn't move.)  The promise is higher speeds over longer distances than DSL or cable.  There is an upcoming standard (802.16e) that would improve the mobility of this (like a high-speed Ricochet service) but that standard isn't finalized.
