The W-Lan-Turbo.

A new generation of W-LAN USB sticks should wireless surfing comfortable. Data flows faster, the connection goes further, and the mini-devices consume less power. But in many home networks are Stoplersteine the turbos ausbremsen.

 

Family life anno 2009: Dad checks the stock prices, little daughter is chatting with friends, and struggling through Sohnemann multiplayer game worlds. So much traffic in a network can quickly lead to the information highway is another road. The page structure takes the video stream jerky.

More Speed: A W-Lan-stick, the n-radio standard, transmits data faster than devices, the g-standard use.

Back on the highway it goes with new USB adapters for WLAN, which has not yet officially adopted the standard for fast wireless networks, IEEE802.11n use. Even older computers can be easily retrofitted so. In theory, could be the maximum surfing speeds of up to 300 megabits per second (mbps) to reach, says Peter Knaak of the Stiftung Warentest in Berlin.

In spite of such transmission rates are the small accelerator frugal in their technical requirements. A computer with Windows XP or a more modern operating system is sufficient, says Fabian Keudell of the magazine "Chip". Modest claims the pins at the Purse: The winner in a test of the "Computer Picture" (issue 2 / 2009), the Hama Wireless LAN USB 2.0 Stick 300 mbps, it costs around 30 euros.

In practice, usually only stay a speed from 60 to 100 Mbit / s remaining, Knaak says. Walls, furniture and other networks disrupt the transmission. But even at this pace takes to transfer a data volume from one gigabyte, according to Fabian Keudell theoretically only one and a half minutes. In practice could be assumed that W-Lan after the n-standard (802.11n) data two to four times faster transfers than a g-standard equipment (802.11g).

The new adapters provide the data for speed, many users currently do not exploit. Therefore advises Knaak, consumers should be buying good about it. If you just surf the internet normally and the network is not compatible with many Mitsurfern share, come with a connection in the currently usual g standard is sufficient. Fully utilized, the possible transmission speed of a n-standard Wi-Fi only at very fast Internet connection or the transmission of large amounts of data in the domestic network.

It is important that the router is the n-standard, because it is the speed in the network provides. Works in the g-standard, ie with a gross transfer rate of 54 Mbit / s, fits the W-Lan at the stick - even though he is actually faster.

A good date for the purchase of a W-Lan sticks could conclude a new DSL contract that says of Keudell. While supported by Internet service providers usually have standard g router provided. New customers may be the money for a subsidized router but also saving and for a surcharge of around 20 euro a passable standard n-capable routers to buy.

Especially as this in addition to its higher transmission speed, a number of other advantages. To consume the most pins significantly less power than their predecessor models. This will benefit users in particular, with their notebook often in battery mode. In addition, many stick to encrypt the data transmitted by the so-called WPS process automatically. Users need not enter more complicated passwords, but only to push a button.

In addition, radio equipment in accordance with the standard n-much further: in theory, ten times, but at least twice as far as the g-standard, says of Keudell. You can also corners, in the devices with g-standard no longer penetrate. Nevertheless, consumers should be careful where they set up their computer. Ideal would be if the router and computer vision in conjunction with one another.
