1. Choosing the right equipment: what kind of router do you need for your TV?

Not every router is capable of providing a stable connection for Smart TV, especially when it comes to broadcasting video in 4K HDR or online games through Google Stadia/Xbox Cloud GamingMain selection criteria:

• 📶 Wi-Fi standard: minimum - 802.11ac (Wi-Fi 5), optimal - 802.11ax (Wi-Fi 6) for TVs with support 2.4 GHz + 5 GHz.
• 🔄 Dual-band operation: TVs often perform better in the range 5 GHz (less interference), but some models (for example, budget ones) Xiaomi Mi TV) support only 2.4 GHz.
• 📦 Number of antennas: from 4 (for small apartments) to 8 (for houses with thick walls). Models with MU-MIMO (For example, ASUS RT-AX88U) cope better with the simultaneous operation of several devices.
• 🔌 LAN ports: at least 1 port Gigabit Ethernet (1000 Mbps) for wired connection of TV if Wi-Fi is unstable.

For most users, mid-range routers will be the optimal choice:

Critical error: Many users buy cheap routers that only support Wi-Fi 4 (802.11n), which are physically incapable of delivering speeds above 300 Mbps. 4K streaming requires a minimum of 25 Mbps, but considering other devices on the network (smartphones, laptops), the speed reserve should be at least 100 Mbps.

⚠️ Note: If your TV supports Wi-Fi Direct (for example, models Sony Bravia 2022+), check compatibility with your router. Some budget models may not work correctly with this technology, which will make it impossible to use the function. Screen Mirroring.

2. Setting up a Wi-Fi channel. In the range 2.4 GHz choose the least loaded channel (use apps like Wi-Fi Analyzer). For 5 GHz Channels 36–48 or 149–165 are recommended.
3. Enabling the mode 802.11r (Fast Roaming). Useful if the TV frequently reconnects (relevant for models with Android TV).
4. Disable Wi-Fi power saving. Some routers (eg. TP-Link) by default reduce the transmitter power, which can lead to connection breaks.

For optimal performance of your TV, it is recommended to create a separate network for multimedia (guest network or VLAN). This will allow:

• 🎯 Prioritize TV traffic via QoS (for example, in the settings Keenetic this is done in the section Traffic priorities).
• 🔒 Restrict access of other devices to local resources of the TV (for example, to DLNA server).
• 📶 Allocate a separate SSID with a fixed channel (e.g. TV_Net_5G on channel 44).

⚠️ Attention: If your router is enabled WPS, disable it! This feature is vulnerable to hacking and may lead to unauthorized network connections. In some TV models (e.g., LG WebOS) WPS may conflict with a regular password connection.
