Preparing to set up Wi-Fi: What to check before connecting

Before proceeding to the console menu, make sure that your router and myself Selenga T81D Ready to use. Often, connection issues arise not from user error, but from external factors: weak signal, incompatible settings, or hardware limitations.

Here are some key points to check beforehand:

• 🔌 Power supply for the console: The device must be connected to the network via the original power supply. Using uncertified adapters may cause problems with the Wi-Fi module.
• 📶 Router location: If the set-top box is in another room or behind thick walls, the 5 GHz signal may not be received. For Selenga T81D The optimal distance is up to 10 meters in direct line of sight.
• 🔄 Router operating mode: Some models disable support for legacy standards by default (for example, 802.11b). Make sure mixed mode is enabled in your router settings. 802.11b/g/n for 2.4 GHz.

• 🔄 The router does not issue an IP address (error) IP Renewal or No Internet).
• 🌍 Problems accessing certain websites or services (for example, weather widgets or IPTV won't load).
• 🛡️ Using alternative DNS to bypass blocking (for example, 8.8.8.8 from Google).

To configure IP and DNS manually:

1. Go to Settings → Network → Wi-Fi.
2. Select your network and click Additional settings (or Advanced).
3. Change the IP acquisition type from Auto (DHCP) on Manually.
4. Enter your details:
   • IP address: For example, 192.168.1.100 (must be free on your network).
   • Subnet mask: usually 255.255.255.0.
   • Gateway: The IP address of your router (e.g. 192.168.1.1).
   • DNS 1 and DNS 2: you can specify 8.8.8.8 And 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare).

Save the settings and reboot the set-top box.

⚠️ Attention: If you use double NAT (for example, if the router is connected to another router), manually setting the IP may lead to conflicts. In this case, it's better to leave Auto (DHCP) and set up port forwarding on the main router.

After applying the settings, check your internet access by opening any widget (for example, weather or YouTube). If problems persist, try resetting the settings. Auto (DHCP) and contact your provider - it's possible that the blocking is on their end.
