Maxnet experts recommend connecting TV directly without Wi-Fi, allowing you to watch Smart TV without interference. Why Wi-Fi cannot provide a reliable connection is outlined below in a simple and straightforward manner.

It's no exaggeration to say that today's Smart TV opens up a wealth of opportunities for the user – a huge number of channels and video information becomes easily accessible, there's no need to download it onto a flash drive or disc to watch later on your TV. However, the unique capabilities of Smart TV are not limited to access to films, science shows and cartoons. You get open access to a wide range of useful information and entertainment resources, such as weather, news, music streaming, social networking, etc.


How can you connect Smart TV so that this option works well and nothing can stop you from enjoying your favourite channel, programme or film?

To avoid signal problems Maxnet experts recommend connecting your TV with a cable and not with Wi-Fi.

Important! Channel numbers that don't overlap are 1, 6 and 11

1. The fact is that Wi-Fi devices are susceptible to even small interference from other devices operating in the same frequency spectrum. These are often other Wi-Fi routers, access points or Bluetooth devices.

Wireless networks use two frequency spectrums, 2.4 and 5 GHz. 802.11b/g wireless standards operate in the 2.4 GHz spectrum, 802.11a wireless standards operate in the 5 GHz spectrum and 802.11n wireless standards can operate in both the 2.4 GHz and 5 GHz spectrums.

In the 2.4 GHz frequency band, 11 or 13 channels of 20 MHz (802.11b/g/n) or 40 MHz (IEE 802.11n) with 5 MHz intervals between them are available for wireless networks. A wireless device that uses Wi-Fi as one of the frequency channels causes significant interference to neighbouring channels. For example, if an access point is using channel 6, it will cause heavy interference on channels 5 and 7 as well as on channels 4 and 8 of the intervals.

The figure shows the spectra of the 11 channels. The colour coding denotes groups of non-overlapping channels - [1,6,11], [2,7], [3,8], [4,9], [5,10]. Different wireless networks located within the same footprint must be configured with non-intersecting channels.

2. Another cause of signal dip could be the Wi-Fi n and g network card. For example, in mixed mode the router is not more than 54 Mbit/s, in normal LAN card 100 Mbit/s.

3. Various large objects, walls and mirrors that are positioned between the router and the TV also drastically reduce the signal.

Obstacle Additional losses (dB) Effective distance
Open space 0 100%
Window without tinting (no metallised coating) 3 70%
Tinted window (metallised coating) 5-8 50%
Wooden wall 10 30%
Inter-room wall (15,2 sm) 15-20 15%
Supporting wall (30,5 sm) 20-25 10%
Concrete floor/ceiling 15-25 10-15%
Monolithic reinforced concrete slab 20-25 10%

4. Household appliances can also prevent you from watching your favourite TV show or programme, which is often the cause of Wi-Fi connection degradation.


Microwave microwave ovens. These devices can weaken Wi-Fi signal strength as they usually operate in the same band - 2.4 GHz.

Baby monitors. These devices operate in the 2.4 GHz band and cause interference, resulting in poor Wi-Fi connectivity.

CRT monitors, electric motors, cordless phones and other wireless devices such as Bluetooth devices operating within your Wi-Fi coverage area.

5. In addition, remember that when connected via Wi-Fi devices, the signal loses some of its information, causing the picture and sound to «freeze» when watching channels.


Over the years of working in the telecommunications market, Maxnet network installers have made a huge number of different connections and therefore can say with certainty that there are no such problems when connecting via cable to the television. In this case the signal is more stable and the factors affecting the quality of the connection are much less.

Don't let an unstable signal spoil your mood by interfering with your TV viewing experience.

Maxnet — with care for your leisure time.
