Unable and Cannot Connect to WPA and WPA2 Encrypted Wireless Wi-Fi Network in Windows XP Ne morem in ne morem Povezovanje z WPA in WPA2 Šifriran Brezžična Wi-Fi omrežju v operacijskem sistemu Windows XP

After configuring the security settings of a wireless 802.11a/b/g router or access point (AP) to enable WPA or WPA2 encryption with a Pre-Shared Key (PSK or WPA-Personal/WPA2-Personal), or Radius Server (WPA-Enterprise/WPA2-Enterprise), Windows XP machine cannot or unable connect to the WPA security-enabled wireless network (although Windows XP is able to scan and detect the availability of the Wi-Fi network) with the following error message: Po nastavitvi varnostne nastavitve za 802.11a/b/g brezžični usmerjevalnik ali dostopno točko (AP), da se omogoči WPA in WPA2 enkripcijo s Pre-Shared Key (PSK ali WPA-Personal/WPA2-Personal) ali Radij Server (WPA -Enterprise/WPA2-Enterprise), Windows XP stroj ne more ali ne more povezati z WPA varnost omogoča brezžično omrežje (čeprav operacijskega sistema Windows XP je sposoben skenirati in odkrivanje razpoložljivost v Wi-Fi omrežja), s sporočilo o napaki:

Windows is unable to connect to the selected network. Windows se ne more povezati na izbrano omrežje. The network may no longer be in range. Mreže ne sme več biti v dosegu. Please refresh the list of available networks, and try to connect again. Prosimo, osvežite seznam omrežij za povezavo in poskusite znova.

WPA (Wi-Fi Protected Access) and WPA2 (RSN Robust Security Network or IEEE 802.11i-2004) is more secure encryption algorithm for wireless or WiFi network, especially WPA2, which introduces new AES-based algorithm, CCMP encryption which is considered fully secure. WPA (Wi-Fi Protected Access) in WPA2 (RSN Zanesljivi varnostni mreži ali IEEE 802.11i-2004) je bolj varna šifriranja za brezžični ali WiFi omrežja, zlasti WPA2, ki uvaja nove AES temelji na algoritmu, CCMP enkripcijo, ki se šteje za popolnoma varno. WPA2 certification is now mandatory for network devices to be certified by Wi-Fi Alliance as “Wi-Fi CERTIFIED”. WPA2 certificiranja je zdaj obvezna za omrežne naprave, ki mora biti potrjen z Wi-Fi Alliance kot »Wi-Fi CERTIFICIRA".

The Windows XP (with or without SP1) system does work properly and connect perfectly to the wireless network if the router, WAP (wireless access point) is configured to enable and use WEP 64-bit/128-bit/225-bit security encryption, which is less secure than WPA2 and WPA. V operacijskem sistemu Windows XP (z ali brez SP1) sistem deluje pravilno in popolnoma povezati z brezžičnim omrežjem, če je usmerjevalnik, WAP (brezžična dostopna točka), je nastavljen tako, da omogoči in uporabi WEP 64-bit/128-bit/225-bit varnostno šifriranje , ki je manj varen kot WPA in WPA2. Beside, in Windows XP SP1 computer, the WPA encrypted wireless network can be connected without error too. Poleg tega, v operacijskem sistemu Windows XP s servisnim paketom SP1 računalnik je WPA šifriranega brezžično omrežje se lahko povežejo brez napak preveč. The error only surface on pre-SP2 Windows XP on both WPA and WPA2 protocols, and WPA2 on Windows XP SP2. Napaka samo na površini pre-SP2 za Windows XP na obeh WPA in WPA2 protokolov in WPA2 na Windows XP s servisnim paketom SP2.

By default, Windows XP does not has native support for WPA in Windows XP (which only added via By default, Windows XP ne je native podpora za WPA, v operacijskem sistemu Windows XP (ki se dodajo samo z KB815485 WPA support patch KB815485 WPA podpora obliž and via Service Pack 2), and no native support for WPA2 until Windows XP SP3. in preko Service Pack 2), in ne native podporo za WPA2 do Windows XP SP3. To verify that the unable or cannot connect to the wireless network is indeed cause by lack of support in Windows XP, right click on the Network Connections icon on the system tray (notification area), then go to Wireless Network tab. Da preveri, ali se ne more ali ne more vzpostaviti povezave z brezžičnim omrežjem je dejansko povzroči pomanjkanje podpore v operacijskem sistemu Windows XP, z desno kliknite na Network Connections ikono v sistemski vrstici (priglasitev področju), potem pojdi na brezžične mrežne kartice. Select or manually add in the SSID for the wireless network, then click on Data Encryption option. Izberite, ali ročno dodati v SSID za brezžično omrežje, nato kliknite Data Encryption možnost. If Windows XP supports WPA and WPA2, you will see its options appear in the drop-down list, in addition to usual WEP. Če operacijski sistem Windows XP podpira WPA in WPA2, boste videli svoje možnosti na spustnem seznamu, poleg običajnih WEP.

To let Windows XP pre-SP2 system provides support for WPA WiFi network security encryption method, download and install Če želite, da Windows XP s servisnim paketom SP2 predhodno sistem zagotavlja podporo za WPA WiFi varnost omrežja metodo šifriranja, prenesite in namestite KB815495 KB815495 ( ( KB article KB članek ), or upgrade to ), Ali nadgradnja Windows XP SP2 Windows XP SP2 . .

To provides operating system support for WPA2, download and install the newer Če želite operacijski sistem zagotavlja podporo WPA2, prenesite in namestite novejši KB917021 KB917021 Wireless Client Update for Windows XP with Service Pack 2 (validation required at Wireless Client Update for Windows XP s servisnim paketom Service Pack 2 (validacijo zahtevajo na Microsoft Download Center Microsoft Download Center , or user can direct download the , Ali uporabnik lahko prenesete neposredno WindowsXP-KB917021-v3-x86-ENU.exe WindowsXP-KB917021-v3-x86-SLV.exe ) or older ) Ali starejših KB893357 KB893357 Wi-Fi Protected Access 2 (WPA2) and Wireless Provisioning Services Information Element (WPS IE) update for Windows XP SP2 (validation required at Wi-Fi Protected Access 2 (WPA2) in Wireless Oskrbo Services Information Element (wps IE) posodobitev za operacijski sistem Windows XP s servisnim paketom SP2 (validacijo zahtevajo na Microsoft Download Center Microsoft Download Center , or user can direct download the , Ali uporabnik lahko prenesete neposredno WindowsXP-KB893357-v2-x86-ENU.exe WindowsXP-KB893357-v2-x86-SLV.exe ) or more recommended, upgrade to ) Ali več, priporočljivo, da nadgradi Windows XP SP3 Windows XP SP3 , which now incorporates the WPA2 hotfix and implements the WPA2 IEEE 802.11i wireless networking standard natively. , Ki sedaj vključuje WPA2 sprotni popravek in izvršuje WPA2 IEEE 802.11i brezžičnim standardom natively mreženja.

After installing the WPA and/or WPA2 support into Windows XP and restarting the computer, if the system has a client wireless card with WPA/WPA2-capable firmware and WPA/WPA2 drivers, Wireless Zero Configuration (WZC) displays a WPA2 designation when user view the available wireless networks. Po namestitvi WPA in / ali WPA2 podporo v operacijskem sistemu Windows XP in znova zagnali računalnik, če je sistem odjemalec brezžično kartico s WPA/WPA2-capable firmware in WPA/WPA2 voznikov, Wireless Zero Configuration (WZC) prikaže WPA2 označbo, ko uporabnik Glede na razpoložljiva brezžična omrežja. For example, Security-enabled wireless network (WPA) and Security-enabled wireless network (WPA2) , instead of just plain “Security-enabled wireless network”. Na primer, varnostno-omogočena brezžična omrežja (WPA) in varnost-omogočena brezžična omrežja (WPA2), namesto samo navaden "Varnost omogoča brezžično omrežje."

As mentioned just now, operating system support for wireless security protocol especially WPA2 is just a piece of the jigsaw puzzle. Kot je omenjeno le sedaj, operacijskega sistema podporo za brezžično varnost WPA2 zlasti protokol je le košček v Slagalica. The PC must also has client wireless card, or built-in wireless receiver, or Wi-Fi network adapter that supports WPA and WPA2. PC mora tudi odjemalec brezžično kartico ali vgrajeni v brezžičnega sprejemnika, ali Wi-Fi omrežna kartica, ki podpira WPA in WPA2. If you just bought the wireless network adapter recently, chance are the WLAN adapter will support WPA and WPA2 by default. Če ste jo pravkar kupil brezžično omrežno kartico pred kratkim, so priložnost za WLAN adapter bo podpiral WPA in WPA2 privzeto.

If after installing the WPA2 (or WPA) update hotfix or latest service pack in Windows XP, yet WPA or WPA2 is still unsupported and system unable to connect to wireless network, check the website of the WLAN adapter or wireless card for any new updated WLAN driver that capable of enabling WPA and WPA2 functionality on the WiFi receiver adapter card. Če po namestitvi WPA2 (ali WPA) posodobite sprotni popravek ali najnovejši servisni paket za Windows XP, vendar pa WPA ali WPA2 še nepodprt in sistem ne more povezati z brezžičnim omrežjem, preverite spletni strani WLAN adapter ali brezžično kartico za vsak nov posodobljen WLAN voznika, da sposobna omogočiti WPA in WPA2 funkcionalnost na WiFi sprejemnikom adapter kartico. Some WLAN adapter may require a firmware update to support WPA and WPA2. Nekatere WLAN adapterja lahko zahtevajo posodobitev strojno-programske opreme za podporo WPA in WPA2.

If you have an old wireless card that the only option available is WEP, and has no updated driver for it, then WPA/WPA2 won't work simply because the WLAN adapter does not support it. Če ste stari brezžično kartico, da je edina možnost, ki je na voljo WEP, in ni posodobljen gonilnik zanjo, potem WPA/WPA2 ne bo delovala preprosto zato, ker je WLAN Adapter ne podpira. In this case, fallback to WEP encryption, or get a new wireless adapter. V tem primeru, za nadomestno WEP šifriranje, ali dobim nov brezžični vmesnik.
