Hello community, I have encountered a mysterious issue with my home internet connection. An unidentified device named "Shenzhen Hualistone Technology" has appeared on my network. My main router is an Asus RT-AX86U, which only has one wired device (a FireTV stick) and the rest are connected via WiFi. The unknown device shows on IP xxx.xxx.xxx.242 at 2.4GHz, and it even appears as a wired device on my second router (an Asus RT-AC68U configured as a repeater). I powered off the second router and even the Huawei modem, but the device still appears. After blocking its MAC address, it vanished from the active list. Could this be an unnoticed IoT device or a potential security breach? Any further advice is appreciated!

Seen this dozens of times over the years. Shenzhen Hualistone is basically the generic networking name for hardware modules found in white-label Tuya and Govee products. If youve got any cheap smart plugs or LED strips from Amazon, thats almost certainly your culprit. The wired status on the AC68U happens because repeaters use MAC address translation. The main router sees the repeater as the source, so it mislabels the wireless client as a wired connection. To find the exact unit, try these steps:
- Check the MAC address sticker on any smart plugs or bulbs you own
- Look for devices registered in the Tuya Smart or Smart Life apps
- Power cycle your IoT devices one by one while watching the client list in the Asus GUI Usually, its just a smart bulb or a random controller you forgot about. Unless you see it sending massive amounts of data to an unknown external IP, its likely harmless. Personally, I just throw all these cheap devices on a separate guest network to keep them isolated from my main hardware.

I had a similar mystery in my network logs a while back. In my case, it turned out to be a phantom entry caused by the router’s internal mapping error of client connections. After restarting the router and some minor configuration adjustments, the “ghost” device eventually disappeared. However, if it reoccurs, it’s worth checking if any of your devices have been compromised or if an unauthorized access point is nearby. It might just be a quirk, but staying proactive with network monitoring is key.
