What wireless network card to I need to use on my WLAN ?

In 1997 the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN standard.

They called it 802.11 after the name of the group formed to oversee its development. this first version only supported a maximum network bandwidth of 2 Mbps today it has been improved to over 300Mbps using MIMO devices based on this first version, a comparable wired LAN on CAT5e Ethernet twisted pair cables usually is classes at a minimum of 10Mbps to a maximum speed of 100Mbps (often called 100/10Mbps)
Here is a summary of all the Wi-Fi versions and letter numbers upto the present day in 2010.

In 1999, the 802.11b specification was released for the the domestic market, supporting bandwidth up to 11 Mbps at the same time the 802.11a was released for the business market upporting bandwidth up to 54 Mbps it was much more expensive and signals had more difficulty penetrating walls and other obstructions so it was dropped.
In 2003, WLAN products supporting a newer standard called 802.11g it combines the best of both 802.11a and 802.11b it supports the same bandwidth as 802.11a of 54 Mbps (hence it is often called 54g this is the Wi-Fi standard), it uses the 2.4 Ghz frequency for greater range the 802.11g technology is backwards compatible with 802.11b, all WLAN cards will call this 802.11b/g
Some versions offer 128g which is 54g twice but only if the router will supports this doubled speed, the majority of all routers use a V.90 modem which will only support 54Mbps (aka 54g).


The newest IEEE standard in the Wi-Fi category is 802.11n (called MIMO technology) . It was designed to improve on 802.11g in the amount of bandwidth supported by utilizing multiple wireless signals and using antennas instead of one, it support data rates of over 100 Mbps upto 300Mbps and also offers somewhat better range over earlier Wi-Fi standards due to its increased signal intensity. All 802.11n equipment will be backward compatible with 802.11g/b networks.




Most internal WLAN cards are plug and play on the PCI bus, however more and more version are being provided as either a USB or PCMCIA version for laptops and desktops, this version below will work with all versions 11b, 54g and 11n upto 300Mbps ( if the router that you have will suport it.





The latest technology is called Wi-MAX is designed for long-range networking spanning miles or kilometers as opposed to local area wireless networking or WLAN. The other end of the Wireless technology spectrum, that split from 802.11b is called BlueTooth and works up to a maximum distance of 10 Meters used exclusively as the standard in Mobile Phone devices like headphones and short distance inter-connection to other phones and PC's.

How can i download ms office 2003 download free?


Well my suggestion is that you take up and IEEE membership. IEEE stands for Institute of Electrical and Electronics Engineers and is a nonprofit organization which stands for the advancement of technology innovation related to electricity.
IEEE members can get free Microsoft software directly from Microsoft plus they will get IEEE membership which is highly valuable.
For more details about the IEEE membership visit their website http://www.ieee.org/index.html
Good Luck

I have a laptop running 802,11 g/b and vista and I Cant connect to linksys wag160n wireless router(802,11 n). laptop sometimes recognises network but when I try to connect it wont. could you help ?


Hi, You cannot connect across wireless protocols. In other words to connect to 802.11 n you need an "n" adapter.

Now, the router should be backward compatible & provide wireless g/b but you may find that when you search for networks it will be listed as a seperate network name (from the same router)

Try searching for this other network. Your router documentation should advise you of its default name & any set up process

Can you please tell me what is more reliable and better?


I'm afraid you need to clarify:
If you refer to (old) Specification 802.11 — it applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS). you can compare with 802.11b (also referred to as 802.11 High Rate or Wi-Fi) — an extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1-Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet.
But as suggested by ricerz from Wikipedia:
IEEE 802.11 is a set of standards implementing by apple wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz spectrum bands. They are maintained by the IEEE LAN/MAN Standards Committee (IEEE 802).
You cannot compare 802.11 with 802-11b: 802-11b is an implementation of part of the 802.11 standard.
You can compare: 11a (using 5Gh band) with 11b (using 2.4 Gh band)
You can compare 11 b with 11g or 11n standard. and select according to environment.
As per my personal experience Industrial or hostile installation was frequently done using 802-11A (less interferences, 54 Mb bandwith) new N standard with a peak of 300 Mb is now changing the scenario.
New accessories: Boosters, external antenna, WDS protocol to bridge WLan router, and new long range Wi-Fi are continuously changing performance, results and configuration
