How to choose a wifi USB adapter for TV
The usual Wi-Fi USB adapter looks like a flash drive and plugs into one of the USB connectors of the TV. But the USB port does not mean that now you can buy any adapter and connect it. If the TV has no need of drivers, this adapter will not see it. Therefore, to avoid mistakes, choose the adapter that is specific to the manufacturer of the TV. But sometimes the price they are rather large.
Depending on the ports on the TV, you can buy a Wi-Fi adapter with different output: USB, PCMCIA or HDMI. PCMCIA WI-FI adapter is a legacy option, since new TVs released without this connector. But if You have a way out, and the TV can be configured to connect to the Internet, then select it.
TV models Philips, Panasonic, Samsung, Sharp, LG, Sony and Toshibaмогут not work with regular Wi-Fi USB adapters, which are suitable for laptops. Often they simply do not see. Other choice is to buy a USB adapter from the manufacturer of the TV.
For televisions other brands suitable alternative adapters c HDMI connector, for example Stream TV DIB-200. It features high speed transmission and powered by the USB port of the TV or external power.
The compatibility of the adapter with the TV
When you select Wi-Fi adapter, always check its compatibility with your TV. On the adapter itself often write compatible models or entire brands (e.g. Samsung, LGSeries 5, etc.).
But what happens if you take a risk and not buy the original charger? Because branded are much more expensive than usual.

Standard signal transmission
Also, buying an adapter, note that the standard by which he works. You need to look at the standards of the router, which distributes Wi-Fi, and select a model with the same data. Now there are several Wi-Fi standards. From the selected standard depends on the data rate.
The highest quality reception and transmission of signal provides IEEE 802.11 n, the throughput is 300 Mbps:
- 802.11 a — max 54, real to 2
- 802.11 b — max 11, real to 3
- 802.11 g — max 54, real to 24
- 802.11 n — max to 150, to 50 real
- 802.11 n — max to 300, up to 150 real
But, apparently, in practice, Wi-Fi adapters have lower throughput. This is due to the interference through walls and other obstacles, as well as the transmission speed depends on the number of devices using Wi-Fi. Because initially choose a maximum router and adapter on a TV to provide a fast signal transmission.
The frequency of the device
When choosing a wifi adapter, look carefully at what he’s working frequency. If Your router runs at 5 GHz and the 2.4 GHz adapter, they will not work.
Adapters operate at frequency of 2.4 – 5 GHz:
- 802.11 a — 5 GHz
- 802.11 b — 2.4 GHz
- 802.11 g — 2.4 GHz
- 802.11 n — 2.4/5 GHz
Transmitter power — stability
The power adapter depends on its speed and stability. In a large apartment it is better to choose powerful transmitters in order not to obtain low quality signal. Optimal are models with a capacity of 17 to 20 dBm. Stable and quality connection in this case is guaranteed.
ВыбираяWi-Fi adapter, note the distance between the TV and the router, or rather range of the transmitter. Keep in mind that the greater the distance and number of obstacles on the way to the signal, the lower its speed and power. Even when you are in the right area, but having a sufficient number of obstacles the signal is not very good.
Wi-Fi channel should be protected, as it can crack and thus worsen the signal is sent. It is better to buy adapters with WPA or WPA2.
They ensure network protection against hacking. While WEP is less secure and outdated.
Is there an alternative WI-FI adapters for TV
Those who do not want to buy an expensive brand receiver, you can buy an inexpensive Wi-Fi router. It must be installed near the TV and use network cable to connect. After that, the router must be configured in bridge mode with main router, which will be the Internet.
A more complex scheme for TVs Samsung is to buy a Wi-Fi adapter D-Link DWA TP-LINK TL-WN727Nv3 or Zyxel NWD2105 and flash it.
Sew new IDs in the adapter in Ubuntu Linux. Other operating systems are not suitable because they can damage the adapter.
For the firmware of the transmitter you need to:
- to upload the ISO image of Ubuntu;
- to write the downloaded image to removable media;
- download driver Wi-FI adapter;
- flash IDs VID and PID on # iwprivra0 e2p 208=04e8 # iwprivra0 e2p 20a=2018;
- but any wrong step may damage the adapter and make it generally unsuitable.
