How to Extend Laptops Wi-Fi Range

There are simply too many generic Wi-Fi tips suggesting that if you are having trouble getting an acceptable Wi-Fi signal, you need to move closer to the access point. Of course, this is the most obvious and the most affordable solution. But, often you pretty much stuck on your location or you don’t want to look silly by moving randomly while pointing your notebook to all direction. The real answer is by improving the range of your notebook.

Enhanced-capability notebook adapters will go a long way toward solving the dilemma of being too far away from a signal source. You can use these devices to improve your chance of connecting a hotspot with your notebook at a longer distance. Before rushing right out to buy all the parts and pieces necessary, give external Wi-Fi adapters a good and thorough test. If you are still facing problems obtaining a steady connection, then you should go back and try one of these ways to extend the Wi-Fi radio-transceiver range:

Improving antenna gain: If you have bought one of those Wi-Fi adapters that use a removable antenna, then you need to get a high-gain antenna. Most external Wi-Fi adapters come with an antenna that is rated at approximately 2 dB – but even those that already have high-gain antennas will do better when connected with a dedicated external high-gain antenna.

Directional and omnidirectional: The difference between directional and omnidirectional antennas is just like comparing a lantern and a lantern (respectively). A lantern casts its light in all directions; a flashlight concentrates its light as a single narrow beam. Many antennas are basically omnidirectional to maximize coverage and reach moving devices. The term antenna gain essentially refers to the signal focus. A high gain antenna emits a tightly focused field; while a low-gain antenna emits a widely focused field. A high-gain antenna, therefore, is not actually more powerful than a low-gain antenna. As a matter of fact, there is really no signal output increase in a high-gain antenna, it’s just that the signal is more focused.

Output amplification: If you have found that a high-performance 200 mW notebook adapter does not quite cut the mustard (or if you are just plain power-hungry), there are a few wireless amplifiers that offer power output until up to 1000 mW (1 Watt). Never try to amplify a high-output external adapter. You will only fry the amplifier. An amplifier is designed to support the input power of a typical wireless adapter -approximately between 32 mW to 63 mW.

Combining high-gain antenna and amplified output: By far the most effective configuration for extending the Wi-Fi range is by combining a high-gain antenna and high-output amplifier. You’ll be pleased to know that several manufacturers sell complete Wi-Fi extension kits that include the high-gain antenna, the amplifier, and an adapter.
