Wi Fi question

Yes definitely ,I think i need lots more information about router version, IEEE standard.
basically adapter that uses mobile phone networks to provide broadband as a WiFi Dongle while USB WiFi adapter can be used to connect your PC to and existing wirless network provided by a wireless router.
but first you should find out what kind of Internet router you are using and always purchase a Wi-Fi adapter that is compatible with the Wi-Fi standard of your wireless router.

Wi-Fi Protected Setup (WPS; originally Wi-Fi Simple Config) is a flawed network security standard that attempts to allow users to easily secure awireless home network, but some networks using this standard could fall to brute-force attacks if one or more of the network's access points do not guard against the attack.[1][2]

OK! Quite briefly...WPAstands for Wi-Fi protected access. It is a standard security protocol implemented by Wi-Fi alliance to secure wireless computer networks. WPA standard is an advancement over WEP (standing for -->Wired Equivalent Privacy) standard that had some security issues... WPA implements most of the IEEE 802.11i standards and provides greater security than WEP.

Did this help?

Try resetting the Internet sett on tab and connect again

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks.

You need a WPA or WPA2 key to connect your Game console wireless to the wireless accespoint.

Wired Equivalent Privacy (WEP) is a deprecated algorithm used to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using a radio and are thus more susceptible to eavesdropping than wired networks.

Setting WEP up is done from the wireless security tab of your router configuration, this is usually accessed from your computer using the web address http:\\192.168.1.1 by default. It consists of a pass-phrase and a key. the pass-phrase is used to generate an encryption key, this is then necessary to use any packets (Bits of data) transferred over the air.

Beginning in 2001, several serious weaknesses were identified by cryptanalysts with the result that today a WEP connection can be cracked with readily available software within minutes.[2] Within a few months the IEEE created a new 802.11i task force to counteract the problems. By 2003, the Wi-Fi Alliance announced that WEP had been superseded by Wi-Fi Protected Access (WPA), which was a subset of then upcoming 802.11i amendment. Finally in 2004, with the ratification of the full 802.11i standard (i.e., WPA2)

Activate and connect to a WLAN
1.In range of WLAN network, access an application or menu that needs a wireless connection.
2.On the Home screen, press <Start> → <More> → Settings → Connections → More... → Wi-Fi.
3.Press <Menu> → Turn On Wi-Fi.
The device will display available WLAN connections.
4.Select a network profile from the list.
The device will attempt to connect to the WLAN.
5.Select a network type and press <Next>.
6.Enter a pre-shared key for WLAN and press <Next> or <Finish>.
7.Set the IEEE 802.1x access option and the extensible authentication protocol (EAP) type and press <Finish> (if necessary).


Create a new WLAN
1.On the Home screen, press <Start> → <More> → Settings → Connections → More... → Wi-Fi.
2.Select New...
3.Enter a network name, configure connection settings, and press <Next>.
4.Enter network authentication settings and press <Next>.
5.Set the IEEE 802.1x access option and the extensible authentication protocol (EAP) type (if necessary).
6.When you are finished, press <Finish>.

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

No, but it is based on an IEEE 802.11 standard. Wi-Fi Protected Access is derived from the forthcoming IEEEi draft standard and is designed to be forward-compatible with that standard when it is published.
