Firstly, most desktop computers, as well as some TVs, laptops do not contain a network Industry control wifi module communication with a router. Secondly, the owner has a choice: connect devices via a cable or use an external device to receive a signal.
The impossibility or unwillingness of a wired connection leads to the choice of the second option. There are also internal modules for PC, but they are more difficult to install, and such devices are not suitable for other devices. Next, let's talk about what a Wi-Fi USB module is and how to choose one.
Perhaps someone already guess that an Industry control wifi module is such devices for receiving a wireless signal. As well as, you need to understand that such a Wi-Fi module for a computer and other devices can greatly expand the functionality of any device to which it is connected.
The main task of the device is to provide the possibility of interaction between the Wi-Fi router and any other gadget.
Moreover, it is such a Wi-Fi whistle costs mere pennies. At a price of up to $ 10, it allows you to upgrade even old devices and provide Internet access. Compared to a new computer, TV and similar devices, the module is really cheap.
A small body a couples of centimeters long and an antenna for better signals receptions. Further, to connect external modules, a classic USB connector is used, since it is present on almost all devices after 2010.
Another reason why you need an Industry control wifi module is the expansion of the supported frequency range. Now routers with a mixed mode of operation at 2.4 GHz and 5 GHz are popular. At a frequency of 2.4 GHz, the maximum data transfer rate is 300 Mbps, and at 5 GHz - 700 Mbps.
A wireless USB module can be of several varieties: Furthermore, if the receiving device is already built into the case, the coverage area and signal quality will be less, but their cost is also more affordable. Later, Models with external antennas (built-in or plug-in) are better, as they provide more stable and better reception.
Industry control wifi module connect to connectors on the motherboard in the case of a desktop computer, to which their use limit. We can connect USB devices to the corresponding port on any equipment. Their main advantage is the ease of connection.
On 2.4 GHz or 5 GHz
At a lower frequency, there are restrictions on the speed and range of data transmission. 5 GHz models are faster, but also much more expensive.
There are other varieties, but the differences between them are not so significant as to dwell on them in detail.
It is important to know that such a Industry control wifi module for a TV and other devices works exactly the same as the integrated modules. All data from the router is transmitted to an external module, from there to the data processing environment, and only then the result is displayed:
Moreover, it is most important for the module to work, special drivers usually need. They can be set automatically or manually. With their help, we can adjust the operation of the device. Eventually, the Industry control wifi module allows you to configure the network, such as setting the IP, subnet mask, DNS, etc.
However, broadband uses a frequency band on which data packets are transmitted in both directions. The main task of the device is to provide access to a Wi-Fi network for those devices that do not support this technology by default.
Eventually, everyone realizes that such a Wi-Fi module including, many characteristics that you should pay attention to before buying. If you need a module to receive a signal on a PC from a router at a distance of 1 m, we can buy any device, in other cases you should approach the choice more responsibly.
Support for communication standards. The router and Industry control wifi module must have the same values (802.11n, g, b, a).Frequency: For simple tasks, 2.4 GHz is fine. Moreover, if you plan to skip high-speed Internet and the router supports it, it is better to choose a 5 GHz model.
Therefore, the signal strength will more higher, the more stable the connection will be and the wider the scope. Good models have values - 16-20 dbs. Data transfer security. It is important that the module supports WAP and WAP2 data encryption.
Antenna type:
Industry control wifi module models with external, preferably several, antennas will allow you not to experience problems with delays or signal loss even at a distance of 5 m or more from the router, depending on the terrain, building configuration and congestion with other networks, etc.
Subsequently, removing limited Wi-Fi access, you need to figure out the reasons for what is happening. This will allow you to understand in which direction to move in search of a solution.
Here are the most common reasons:
There are even more root causes, but they all fall under the 3 listed categories, so we will not delve into the issue, but immediately proceed to solving the problem.
Firstly, set the correct IP parameter to connect to the router. To do this, enter ncpa.cpl into the search and open the found file. Right-click on the connection, go to "Properties" and open "IP version 4".
Now we switch to manual setting of parameters and enter the IP address of the router in the line (we can find it on the sticker below).
Turn off restrictions on the router. To do this, go to the admin panel (login data is on the router body). Next, turn off "MAC Address Filtering", In addition, if it is active. In the main settings, set the correct "Mode" and "Channel". The first parameter is usually better left in mixed mode or 11n, and the second one should be selected manually. We also turn off "Parental Control" and "Access Control".
Time to move on to ways to remove the Internet restriction. Let's start fixing the problem with the most effective and easy-to-implement methods, gradually reaching the less likely solutions.
Lastly, Industry control wifi module usually looks like 192.168.1.1, but at the end we set a different number, for example, 192.168.1.4. In DNS we enter 8.8.8.8 and 8.8.4.4. Save the changes and try to connect to the router.
