7. Alternative ways to connect your TV to the Internet
If you can't find a suitable Wi-Fi adapter or it doesn't solve the problem, consider these alternatives:
- 🔌 Powerline adapters: Internet is transmitted through electrical wiring. You connect one adapter to the router and the other to a power outlet near the TV. Speeds up to 1 Gbps are possible, but depend on the quality of the wiring.
- 📡 MoCA adapters: They use a coaxial cable (from the antenna) to transmit the internet. This is especially useful if you already have a TV cable installed.
- 📶 4G/5G router: If there is no wired internet, connect the TV via a USB modem (for example, Huawei E3372).
- 🔄 Bridge mode (WISP) on the router: Some routers (eg. Keenetic) can work as a Wi-Fi receiver and distribute the Internet via cable to the TV.
Comparison of alternative methods:
| Method | Speed | Price | Difficulty of setup |
|---|---|---|---|
| Powerline | up to 1 Gbit/s | from 2,000 ₽ | Low |
| MoCA | up to 2.5 Gbps | from 5,000 ₽ | Average |
| 4G router | up to 150 Mbit/s | from 3,000 ₽ | Low |
| Bridge mode | depends on Wi-Fi | 0 ₽ (if your router supports it) | High |
For most users, the optimal solution remains Wi-Fi adapter, but if your TV is in a poor coverage area or maximum stability is required (for example, for online gaming via Google Stadia), consider Powerline or MoCA.
