i-tec USB WLAN Dual Radio A/B/G/N Internal Antenna Adapter


I-tec USB WLAN Dual Band a/b/g/n adapter allows you to connect you laptop or desktop not only to 802.11 b/g network, but also to wireless network based on 802.11 a/n standards. This product should not miss on any network for its great features and easy installation. It can simultaneously work in 2.4 GHz and 5 GHz WL frequence, 2T2R MIMO. In both of these frequencies can independently transmit data at rate up to 300Mbps, so total supports the transfer rate up to 600Mbps. Adapter is able to work as WLAN client and as AP simultaneously in Dual mode.

  • Automatic selection of data rate 1, 2, 5.5, 11, 54, 150 or 300 Mbps, support of 2T2R MIMO technology.
  • Total transfer rate up to 600Mbps
  • Range up to 300m with direct visibility to opposite station or to Access Point.
  • Supports modes point-to-point (Ad-Hoc, Ad-Hoc 802.11a/b/g/n) and point-to-multipoint (Infrastructure).
  • After installation it can work on one MAC interface as a client and on the second one as Access point 802.11 a/b/g/n with PC/NB, which is connected to an Ethernet network.
  • No additional costs for building cabling.
  • Supports WEB encryption (64-bit, 128-bit), WPA/WPA2 and WPA-PSK/WPA2-PSK, WPS.
  • Supports Plug and Play.
  • Easy installation under Windows 2K/XP/VISTA/7 , Linux, Mac OS X.

In case of any problems with installation, technical difficulties or faulty fuctionallity of device find possible solution in FAQ bookmark first.

Question: Adapter should be able to transfer up to 600 Mbps, however specification says 300 Mbps only. Is specification wrong?
Answer: Adapter supports technology MIMO 2T2R which enables tranfer speed 300 Mbps under 802.11N standard. This speed is possible to achieve on both frequencies 2,4/5 GHz independently. This is how the adapter supports transfer speed max. up to 600 Mbps at the moment.

Question: WLAN signal falls or has a short range.
Answer: Please check the signal strength (usually displayed in the status bar near the clock). The ideal condition is when it shows 3-5 pieces. If the signal strength is weak, please move the device to have a better reach.

Please also check whether there is too much interference. Obstacles in the form of walls, buildings etc. causes loss of signal.
