• 📶 Wi-Fi channel: Select Auto or Manually 1, 6 or 11 (least loaded).
• 🔄 Channel width: 20 MHz (reduces interference but reduces speed).
• 🛡️ Safety: Only WPA2-PSK with encryption AES.
• 📦 MTU: 1400 (standard value 1500 may cause breakages).

For routers TP-Link path to settings:

Wireless Mode → Wireless Settings →
- Mode: 11b/g/n mixed
- Channel width: 20 MHz
- Channel: 6 (or auto)
- Authentication method: WPA2-Personal
- Encryption: AES

If you have Keenetic, change the settings here:

Wi-Fi → Access Point →
- Standard: 802.11n
- Channel: Auto (or 1/6/11)
- Security: WPA2 PSK
- Encryption algorithm: AES

⚠️ Note: If you have a dual-band router and your TV doesn't connect to 2.4 GHz, try disable 5 GHz temporarily. Some models Selenga T81D (especially with the 2021 firmware) conflict with simultaneously operating ranges.
