Modern TVs have become more like larger smartphones. Many models already have a built-in module for connecting to the Internet or cable entry. But what if the TV is not so fashionable, that is, connection is possible, but only with the use of additional devices?
For example, pulling wires, especially through half a room if the TV with the modem in different places, is inconvenient and not aesthetically pleasing. Moreover, there is a risk of accidentally touching the wire and damaging it if neither the TV itself, then the modem or the input for the wire is very easy. There is a more reliable, simple, but more expensive method - connecting a wi-fi adapter to the TV.
What is a wifi adapter?
If your model of TV does not have a module for receiving a Wi-Fi signal, this does not mean that you can’t connect it to the Internet. In this situation, it is enough to purchase a special adapter suitable for your TV.
Typically, manufacturers recommend using a device of the same brand as the TV. This is due to the fact that it is impossible to install drivers on the TV, and if the TV and the adapter are of the same company, they are a priori compatible.
A receiver connected to the TV picks up wireless waves no worse than the built-in module. In appearance, the adapter resembles a regular USB flash drive and is included in the Usb connector.
But this does not mean that you can take any adapter of the corresponding brand. As with any choice, there are some nuances.
How to choose an adapter for your TV
As mentioned above, it is worth choosing from models of the same brand as the TV. At the moment, several models are considered the most popular wi-fi adapter for lg tv:
- LG AN-WF100 - allows you to easily access any wireless connection. For it to work, the TV must have the NetCast function;
- LG AN-WF500 - helps connect to mobile devices (smartphones) and the Internet. It is also compatible with headsets and sound panels of the same company.
So, in order to choose a suitable module, you first need to study in detail the instructions attached to the TV. But you should also consider that TVs will not work with devices for computers.
It is worth considering a number of parameters possessed by wi-fi receivers for a lg TV, namely:
- compatibility;
- what standard signal;
- what is the operating frequency;
- power value (recommended 17-20 dBm);
- in what radius does it act;
- encryption method.
As for compatibility, you need to look at the technical specifications of the adapter itself and the TV. Also, information can be found on the company's portal. Again, if you take the receiver of the same brand as the TV, it will definitely work.
There are currently several common wi-fi signal standards:
- 11a;
- 11b;
- 11g;
- 11n.
The data rate depends directly on the signal standard.
For each of the above standards, there are 2 indicators - the maximum bandwidth (which can be supported by the device purely theoretically) and real (what the receiver gives out after the fact).
The weakest in bandwidth is 802.11b. Its maximum value is 11 Mbps, and the real one is 3 Mbps. The strongest is 802.11n. There is a maximum of 300 Mbit / s, but actually - 150.
The rest correspond to the following indicators:
- 11a - up to 54, real - 2;
- 11g - maximum 54 Mbps, actually - up to 24;
- 11n is a maximum of 300 Mbps, in fact no more than 150.
But this difference between the maximum value and the real one is not an advertising move or a hoax, but the result of interference that prevents the signal from breaking through. These include walls (not only concrete), any furniture, indoor flowers, signals from other devices. To get maximum throughput, you need to be, figuratively speaking, in the middle of the field.
You need to choose a standard depending on the standard of the modem, then a good signal will be provided.
Operating frequency is also an important factor.When choosing an external adapter for your wireless network, be sure to consider the frequency at which it works. Typically, such devices support from 2.5 to 5 GHz.
Each signal standard has its own frequency range. If the router and the external wireless receiver work at different frequencies, they will not work with each other. So if the frequency of 5 GHz is indicated in the parameters of the router, it means that the module must be selected as well.
Transmitter power is also important. If the specifications indicate less than 17 dBm, a good signal can not be calculated. The optimal value for operation without interruption is a value from 17 to 20 dBm.
Range is the range of the device. This factor is measured in meters.
Usually in the description of the characteristics of the device indicate the values of work indoors and outdoors.
In order to correctly select the range of a device, one needs to consider not only the location of the “box” itself, but also the router. The closer the router is to the TV, the better the signal. But you also need to consider if there are obstacles between the router and the TV - they can significantly degrade the signal quality.
The encryption method is important for your security. He is responsible for hacking resistance and deals with the encryption algorithm. Now the most acceptable are WPA 2 and WPA. Modules with WEP protocol are already outdated.
In addition to branded external adapters, there are many analogues. Yes, they are much cheaper than branded ones. Manufacturers promise that the device will work no worse than the original. But most likely, when the warranty expires, your adapter will not want to work. So, you won’t be able to return it, and continue to use it too. The result - for the purchase of a new device.
If the warranty still remains, and the device does not work, nobody will change it for you. They will answer that the module is working and cannot be replaced or repaired. And all because it is not in him, but in the fact that the TV ceases to perceive it at a certain moment.
You should not buy universal modules because of their low price. They will work until a certain point - updates. As soon as the system is updated, such a device can simply be thrown away. Better to take more expensive, but for a long time.
Connection
When you have already selected and purchased a network adapter, you need to connect it. To do this, just insert the module into the Usb connector and enter the TV menu.
In the network settings, the item “network setup: wireless” will turn color (become available).
If you know the login and password of the router, you can configure it from the list of access points.
If your router has a WPS button, just hold it for 15 seconds. Setup will be done automatically.
To configure a connection to a computer without accessing the Internet, you need to configure a network (Ad-hoc).
That's all, now you have the connected wi fi-module for the lg tv. There is nothing complicated in the connection, you already know the algorithm. Enjoy your viewing and high speeds!
