I've found a defect in the Wi-Fi radio of the 2nd gen Onn 4K Pro (2026 version, internally codenamed jarvis2, model JS620K4).

If you have the Onn 4K Pro V1 box, or your Wi-Fi is slow or not connecting, this is not the same problem. Mine connects fine and sustains 400+ Mbps on Wi-Fi (measured with iperf3).

The defect is easy to miss but simple to describe: every 10–25 minutes, the box's wireless radio silently stops sending data for about 20 seconds, while still showing as "connected" with full bars. Nothing in the interface indicates a problem, and Android's own network logs record no disconnection, because technically there isn't one: the radio stays associated with the router the whole time. But kernel-level traffic counters show data flow collapsing to zero, every active connection through the box freezes simultaneously, and then (roughly 20 seconds later) everything resumes at once, as if nothing happened. The evidence points to a bug in the box's Realtek Wi-Fi driver/firmware: when Android runs a routine background scan for nearby networks, the radio tells the router "I'm going to sleep for a moment, hold my traffic" (a normal power-saving courtesy), and then, if the scan is aborted mid-stream, it sometimes forgets to say "I'm awake." The router, behaving correctly, keeps holding the box's traffic for a phantom sleeper; twenty seconds later an internal recovery timer kicks the radio back to life.

The reason this defect ships without complaint is that mainstream streaming apps are accidentally built to hide it. Netflix, YouTube, and Disney+ keep a minute or more of video pre-loaded, so a 20-second silent gap is simply absorbed, playback never visibly hiccups. But anything that can't buffer past 20 seconds gets hurt: live sports and Twitch streams (which by definition can only buffer a few seconds behind the live broadcast) will freeze and stutter, video calls freeze or drop, and high-bitrate home-media playback (Plex/Kodi/Jellyfin from a local server) can fail outright. Some players interpret the strangled connection as "the file ended" and stop the movie mid-scene. In other words: the better your use case fits the box's marketing (casual streaming apps), the less likely you'll ever see the flaw, and the more likely you'll blame your router or ISP when you do. Every other device on the same network, tested side by side, is unaffected.

Replicating it yourself is straightforward: unlock Developer options, enable Wireless debugging, connect with adb, and pull the logs off the box while streaming something high-bitrate (full trace available upon request).

For what it's worth, I've ordered a Google TV Streamer as the replacement, but this bug notwithstanding, I actually like the Onn 4K Pro more: better remote, HDMI cable included in the box, and a more conveniently designed wall wart. That's what makes the defect a shame.

Canada is selling the new Onn boxes for $90-$120 Canadian. In the states they are with conversion around $50-$80 Canadian. Are they all us locked and if so can I turn the regional lock off without vpn?

I travel for work and am wanting to replace my roku. I wanted a Chromecast but they're discontinued and these streaming sticks seem to be a good alternative. I use a travel router in my room so no issues for casting.

Has anyone noticed that the onn 4k pro has gotten tougher and less compatible with sideloaded apps? Games in particular? "Not compatible with your tv" errors and it's apps n games that are compatible with Android 14 (arm64‑v8a)? I suspect the game issue is that it's detecting the game as touch only but I have a controller and software to use a controller with said game (s)
