What kind of adapters have not been released over the past few years. Sometimes it seems that developers are trying to transfer one interface to another, it would seem, is completely incompatible. This article will talk about the Ethernet - USB adapter. This tandem, by the way, also until recently seemed a little strange. After all, it was considered difficult to transfer the network interface to USB without special electronics.
The article will also provide a description, characteristics and an overview of several key models.
Appointment
The Ethernet USB adapter is used to connect a device equipped with a USB port to the network using a conventional RJ-45. This allows you to free up the main Ethernet connector for other needs. It can also help in a situation if it is absent in the system at all.
General specifications
Outwardly, almost all Ethernet USB adapters are a small box similar to a USB flash drive. It is very convenient to carry in your pocket or small bag.
On one side of the case there is a connector for RJ-45, and on the other, a small piece of wire with a USB “dad”. Sometimes it can be an integral design.
Different versions of the device can be equipped with LEDs that signal its operability.
Since not only the USB interface is available, but also Ethernet, it is often necessary to install the drivers, which are usually included, to integrate the adapter into the system for its proper operation.
Model Overview
For comparison, it is worth considering the main representatives in this niche. Almost all the leading companies producing network and electronic devices participate in the market. Since this is specific equipment, you can find these devices only in some stores or on the entire well-known Chinese goods portal.
Satechi 3 Port USB 3.0 + Ethernet LAN Network Adapter
This Ethernet USB-adapter is made in a classic compact style. On board it carries one Ethernet port, capable of operating at speeds of 10, 100 and 1000 Mbps. A feature of the device is the presence of 3 USB ports, which makes it a compact hub for connecting additional devices, for example, external hard drives or mobile phones to charge them.
To get started, you do not need to install any drivers. The device is immediately ready for use after direct connection.
DUB E-100 from D-Link
Very simple and compact Ethernet network USB-adapter. The most budget version, designed for domestic needs. There is one USB port and a standard RJ-45 connector. Speed characteristics are defined in 10 and 100 Mbps. For the device to work properly, drivers must be installed from the CD-ROM included in the kit. Installation is quite simple and does not require special skills.
Of the features of the adapter, it is worth highlighting reduced power consumption, especially relevant for laptop owners.
Of the supported operating systems, there is the entire line of Windows, as well as MAC OS and Linux.
DUB-1312 from D-Link
In fact, this is an improved version of the previous adapter. It has the same compact dimensions. But it uses USB 3.0, which gives a higher data transfer speed, while guaranteeing backward compatibility with USB 1.0 and 2.0. Ethernet interface performance has also grown and reaches 1000 Mbps.
Just like the younger brother, it requires installed drivers in the operating system. Similarly, energy saving technology is used.
TP-Link UE330
The device is an adapter with a USB-Mom to Ethernet, as well as one standard USB for connecting to a computer.
The presence of 3 USB ports version 3.0, capable of transmitting data at speeds up to 5 Gb / s makes it indispensable as a hub when connecting other devices. If the number of connectors on a PC is limited, then the device will help when connecting additional peripherals.
The adapter is able to work in all known operating systems, without installing drivers.
HP XZ613AA
One of the simplest devices for connecting a network to a computer via USB. By the way, the version used in it is 2.0, which is not so fast. The network element is capable of transmitting data at speeds of 10 and 100 Mbps.
The device can work normally in the Windows line. And to provide an indication there are LED lamps.
HP N2Z64AA
This adapter is less compact, but has an additional USB-connector. Both are version 3.0, which provides high speed data transfer. Well, actually, the RJ-45 connector itself for connecting to the network.
5bites UA3-45-03BK
Pretty interesting adapter model. The cable is separated from the housing and is connected if necessary. Since the device is also a hub, this is an ideal Ethernet USB adapter for the printer. This is facilitated by three high-speed USB connectors guaranteed by version 3.0.
Of the interesting features, it is worth highlighting the automatic algorithm for determining the connection scheme - direct or crossover. The adapter can work with all known desktop systems.
StarTech.com USB31000NDS
This adapter is just an adapter. That is, in one case without any wires placed USB and Ethernet connectors. This is both a minus and a plus at the same time. It will be convenient to place it at the rear of the system unit, however, in a laptop, a “rigid coupling” will sometimes interfere a little.
This USB to Ethernet converter adapter has USB 3.0 version, which gives good performance. The network interface speed is 10, 100 and 1000 Mbps. This is quite enough for comfortable work on the Internet and downloading quite “heavy” files.
The device can automatically detect the wiring diagram, whether it is a crossover or direct.
Wi-Fi NetGear A6100-100PES USB 2.0
Speaking of network adapters via USB, one cannot but consider the Wi-Fi version. This device is nothing more than a wireless adapter, only the Wi-Fi interface is used instead of Ethernet.
To avoid interference and, as a consequence, to reduce speed, the adapter has two frequencies - 2.4 and 5 GHz. Since many household appliances and devices can also operate at 2.4 GHz, a spare at 5 GHz will be an excellent way out of the situation.
The device is very compact and easily fits in a pocket or small handbag.
Of the interesting features, you can describe the special function Push N Connect, which allows you to establish a connection with one click. Naturally, in this case, everything must be pre-configured.
Conclusion
Many craftsmen try to assemble a USB Ethernet adapter with their own hands. However, due to the narrow specificity of the device, this approach is not widely used. Yes, and ready-made prototypes and schemes as such can not be found. Of course, you can create something similar from the elements of "Arduino", but the time and search for components is unlikely to justify the effect of the crafts.
In general, judging by the reviews, few will appreciate this type of network interface card. This is due to the fact that today, on almost any personal computer or laptop, there is always at least one RJ-45 standard connector. Therefore, you may need to install an additional port in very rare cases. In addition, it is sometimes easier to install a ready-made network card in the system. But many still found it useful and use adapters to expand the capabilities of their computers and systems.
