Overview and testing of asus usb ac56
asus usb ac56 review
Wireless networks are developing by leaps and bounds. If recently USB WiFi adapters could only provide normal speed for work and on the Internet, then today the range of their capabilities has greatly expanded. For example, you can connect to the file storage and without long waiting to download or copy large files or play a Blu Ray movie directly from the storage. ASUS presents the fastest solutions before anyone else and today we look at the USB 3.0 WiFi 802.11ac adapter ASUS USB AC56.

The main features of this ASUS USB AC56 WiFi USB card is that it incorporates a selectable dual band with WiFi AC technology. In the 2.4GHz band we can achieve up to 400Mbps of speed thanks to its two antennas in MIMO 2T2R configuration and TurboQAM technology from Broadcom. Regarding the 5GHz band we can get up to 867Mbps of speed thanks to the MIMO 2T2R and WiFi AC technology.

This equipment incorporates all the features of the WiFi AC standard, such as support for 80MHz channel width, 256QAM quadrature frequency modulation and also Beamforming technology.
With  Beamforming we can achieve greater wireless coverage, which translates into a higher wireless speed. Therefore we are facing a WiFi AC1300 (dual band).

Make raspberry pi router

Raspberry pi router must not only distribute the Internet from the Ethernet port, but also from one WiFi adapter to another. This is very useful when traveling. For example, in a hotel it is easy to be in a room where a local access point finishes up badly. A powerful WiFi adapter will even catch a weak signal and distribute it to all available tablets and phones. It can also help save money where Internet charges are taken from each device separately.

Installing Raspbian on Raspberry Pi

This article is about installing Raspbian on Raspberry Pi 3. If you follow all the steps one by one, it's a piece of cake. There are different Linux distributions available, we choose Raspbian on Raspberry Pi . Raspbian is a Linux distribution that has been developed for educational purposes and is optimized for the different models of the Raspberry Pi .Raspbian is a fork from Debian that can be installed as a live system on an SD card or a microSD card. The first version of Raspbian was released in July 2012 as a replacement for the Debian Squeeze version for ARM processors, previously used by the Raspberry Pi Foundation.

Preparation Sd card for Raspberry Pi
Download the SDFormatter V5.0 program and format the micro SD card. Although an 8 GB card is sufficient, I advise you to take a 16 GB card. In terms of price there is not much difference, the advantage is that you never run out of space. Make sure you take a decent card (Class 10 / UHS-I), such as a Sandisk or Samsung. SD cards from 32 GB can cause problems when booting the Raspberry Pi .

Asus USB AC68 Wireless USB Adapter

asus usb ac68 review Wireless USB Adapter with 802.11ac Support
Many modern top-end routers have access points that support connection speeds of 450/600 and 1300 Mbps in the 2.4 and 5 GHz bands, respectively, which is provided by using three antennas and supporting the 802.11n and 802.11ac protocols. But with the choice of customers, the situation is much more complicated. If we talk about the adapters built into smartphones and tablets, then most often they have only one antenna (up to 150/433 Mbit / s), in rare cases - two (up to 300/867 Mbit / s). Little different and the choice in laptops, although there is occasionally possible to find a configuration with three antennas. Unfortunately, the MU-MIMO technology advertised for several years, designed to make more efficient use of wireless communications, remains in an uncertain state in terms of the availability of client devices supporting it in the market.

What power supply do you need for Raspberry PI 3

What you need to know about Raspberry Pi 3 power supply
Raspberry Pi 3 is not a very demanding computer. It works from just 5 volts and 2.5 amps. But the user of "Raspberry" need to make sure that the device receives enough energy. Otherwise, it will work slowly or completely fail.

    Raspberry Pi 3 Power Problems

    With a lack of power, the Raspberry Pi 3 starts to work slowly. And this is a fairly common problem.

    If the "Raspberry" slows down due to lack of power, it displays a corresponding alert in the form of a lightning icon in the corner of the screen. And if this happens, it is recommended to take action. This is necessary not only because of this, the RPi is slower than it is provided for, but also because of this, electronics wear out faster.

    The problem is usually a cable fault. When powering the Raspberry Pi 3 from USB, a regular cord is used (as, for example, for a smartphone). With intensive use in some parts of it there are creases, which breaks the contact, and, therefore, the feeding device begins to experience problems with power consumption.
    Raspberry pi power supply
    The solution to this issue is to replace the cable. For starters, you can take the cord from a mobile device, and try to connect the "Raspberry" through it. If the problem was exactly that, the lightning bolt will stop appearing. But, of course, provided that the corresponding wire is fully functional.

    The second reason is a big length of wire. Often this problem occurs when using a meter cable. For the "Raspberry" the best option is a cord of 30 centimeters or less.

    And the last one is the insufficient power of the Raspberry Pi 3 power supply unit. The third model requires a current of 2.5 Amperes for normal operation. When using a weaker adapter, the Raspberry Pi 3 can slow down or simply not reveal its full potential. Therefore, it is best to use the original power supply. And if there is no such possibility, then other adapters capable of producing 2.5 Ampere.
    For the best raspberry pi power supply we have made a list for you to chose from check it in here

    Power Raspberry pi 3 from battery

    If it is planned that the Raspberry Pi 3 will be powered by a battery, when buying batteries, pay attention to their characteristics. The main thing - they must produce a current under voltage of 5 volts. There should be no problems with this, as most batteries give so much. The second is that they need to generate a current of sufficient strength.
    Raspberry pi battery
    If the Raspberry pi is to be used in the portable mode, it does not have to demonstrate the maximum power it is capable of. Therefore, it is quite suitable battery, giving a current, for example, 1.8 Ampere.

    Power Raspberry Pi from USB port

    Often, "Malin" is used as a media center. And in this case, users often do not want to occupy an extra outlet, but wish to apply power to the Raspberry Pi 3 from a USB TV. This idea seems good only at first glance.
    Raspberry Pi USB port
    The number of volts that the USB port is capable of issuing really equals 5. That's enough for the Raspberry to work. But the current strength is less than required. USB-port on TV gives 0.4-0.5 Ampere. At the same time, for normal operation, Raspberry Pi needs about 2 Amps. Therefore, if you power the RPi from the TV, it will either not start at all, or it will work very slowly. And if Malin is planned to be used as a media center, then it will lack power. Moreover, insufficient current can cause the computer electronics to burn.

    Therefore, it is still better not to be stingy, but to spend a few Dollars on a surge protector with a sufficient number of sockets.

    Proper the right Raspberry Pi 3 power supply is very important that the device works as it should and for a long time. Therefore, care should be taken to ensure that Malina receives electricity in accordance with established requirements.

    Raspberry Pi GND connectors

    If you intend to use the Raspberry Pi in a standalone device, you need to take care of the power. Fortunately, the developers of Raspberry Pi took care of this scenario development, because their device is still positioned as embedded. The picture below shows the Raspberry Pi model B pinout. To help you power raspberry pi 3 from gpio, it is enough to apply 5 volts to 2.4 connectors, connect the power supply ground to one or more of the GND connectors.
    power raspberry pi 3 from gpio
    It is not recommended to apply to raspberry more than 5 + 2% = 5.1V. This must be considered when selecting a power source. Below is a diagram, developed and assembled by me. The scheme is quite simple - the necessary minimum. At the input there is a varistor, the task of which is to “quench” possible power surges. For a better varistor, you can put a resistor of a couple of ohms in front of it. Next comes the diode bridge 2W10, which has a dual task. The first is to rectify the alternating voltage into a constant one if an alternating voltage is applied to the input, for example from a transformer. The second is reverse polarity protection if a constant voltage is applied to the input. Well, then the usual linear stabilizer 78L05 5 volts.
