To clarify:
My TCL TV is the 65-inch C755 model, which supports dual-band Wi-Fi, including 5GHz. It's positioned in the same room as the R3 with a strong signal and no physical obstructions.
I’ve tested the connection using the built-in network diagnostics, and also tried the Speedtest by Ookla Android app (installed via APK). However, the Speedtest app only shows connection quality and signal strength, not actual speed values.
Why I believe the issue is with the R3:
When I connect the TV directly to my main router (Huawei HG8245W5) — bypassing the R3 entirely — all streaming apps work correctly, and the connection behaves normally.
This confirms the issue is not with the TV or its Wi-Fi hardware, but something related to the R3's handling of the connection.
As mentioned earlier, I’ve already tried:
Prioritizing the TV in SmartBOOST
Assigning a static IP + DMZ
Testing DNS changes
Disabling Adblocker
Restarting both the TV and the router
At this point, I’m confident the issue lies in the R3's configuration or firmware. I’m happy to provide logs or perform further tests if needed.
Thanks again for your support.
Best regards.
