Network adapter type

Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibres, wireless communication channels, and storage media. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.

Wi-Fi
i

Wi-Fi

A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider Internet. This gives users the mobility to move around within a local coverage area and still be connected to the network.

Wi-Fi encryption
WPA-PSK
i

WPA-PSK

Wi-Fi Protected Access (WPA) is a certification program administered by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless computer networks. This protocol was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). PSK means that it is only for Pre-Shared-Key mode

,
WPA2-PSK
i

WPA2-PSK

The advanced protocol, certified through Wi-Fi Alliance's WPA2 program, implements the mandatory elements of 802.11i. In particular, it introduces a new AES-based algorithm, CCMP, that is considered fully secure. From March 13, 2006, WPA2 certification is mandatory for all new devices wishing to be certified by the Wi-Fi Alliance as "Wi-Fi CERTIFIED." PSK means that it is only for Pre-Shared-Key mode.

WPA-EAP
i

WPA-EAP

WPA contains the architecture of WEP, but provides additional protection through dynamic keys based on the Temporal Key Integrity Protocol (TKIP) and offers pre-shared key (PSK) or Extensible Authentication Protocol (EAP) authentication via IEEE 802.1X.
EAP - Extensible Authentication Protocol RFC 3748 (Request for Comments) is a general authentication protocol developed by the Internet Engineering Task Force (IETF) that supports various authentication methods (such as user name/password (RADIUS), electronic certification, SIM (Subscriber Identity Module), etc.). EAP is often used for access control in WLAN (Wireless Local Area Network) networks.

WPA2-EAP

Wi-Fi Protected Access 2 (WPA2) is the implementation of a security standard for wireless networks according to the WLAN standards IEEE 802.11a, b, g and n and is based on the Advanced Encryption Standard (AES). It is the successor of WPA, which is based on Wired Equivalent Privacy (WEP), which is now considered unsafe. WPA2 implements the basic features of the new IEEE 802.11i security standard.

Properties

Wi-Fi standard
802.11b
i

802.11b

802.11b has a maximum raw data rate of 11 Mbit/s and uses the same media access method defined in the original standard. 802.11b products appeared on the market in early 2000, since 802.11b is a direct extension of the modulation technique defined in the original standard. The dramatic increase in throughput of 802.11b (compared to the original standard) along with simultaneous substantial price reductions led to the rapid acceptance of 802.11b as the definitive wireless LAN technology.

802.11g
i

802.11g

This works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s, or about 19 Mbit/s net throughput. 802.11g hardware is fully backwards compatible with 802.11b hardware.

,
802.11n
i

802.11n

802.11n is a proposed amendment which improves upon the previous 802.11 standards by adding multiple-input multiple-output (MIMO) and many other newer features. Though there are already many products on the market based on Draft 2.0 of this proposal, the TGn workgroup is not expected to finalize the amendment until November 2008.

Kann nur 2 Sterne geben und zwar aus folgenden Gründen:

1. Hoher Preis (eindeutig zu viel für das was man bekommt)
2. Schlechter Empfang. Ich hatte vorher eine relativ billige Karte drin und mit dieser habe ich immer 4 Striche oder so 90% erhalten. Mit dieser Karte habe ich nur 2 Striche oder knapp 70%.
3. Software ungenügend / zumindest unter Win7 nicht verwendbar. Der mit gelieferte Verbindungsmanager hat sich immer wieder aufgehängt und wollte sich dann nicht mehr mit dem Internet verbinden (musste immer neu starten). Als Fehler Meldung kam immer das das Gerät inaktiv sei, was aber komisch an der Sache war, ist das ich beim Suchen nach Netzwerken alle Gefunden habe und trotzdem konnte ich mich nicht mehr verbinden.

Ich musste dann die Software deinstallieren und nur den Treiber drauf machen, nun gehts ganz gut.

Ich habe mir die Karte eigentlich extra gekauft, weil ich schon einen D-Link Router habe und mit dem sehr zufrieden bin. Aber diese Karte zu diesem Preis ist einfach nur eine Frechheit.

Habe mir nun extra bessere Antennen gekauft damit ich eine bessere Verbindung habe.
