Question

Hui Zhou Gaoshengda Technology Co.,LTD in my Network

Today I set up a ASUS RT-AC58U router, and added NordVPN to the Modem using OPENVPN (in router settings). I downloaded the app provided by ASUS to monitor my network traffic. I was shocked to see the following company „Hui Zhou Gaoshengda Technology“ as part of my network. I have no idea how did they join it, and what does it mean. I blacklisted the device from my device connection.

Wondering if any of you had similar experience with ASUS & NordVPN. Is it a security flaw? Any suggestion would be really helpful.

Answer
Of you have some SmartHome, IoT or solar panels.

I can't guess what all is on your network but the HZGTC LTD company you mention makes a lot of things including a WiFi module you might find in solar panel management, IoT or any number of WiFi enabled devices.

This does not mean there is a security issue yet. It only means you may learn more about your WiFi devices.

No smart home or solar panel

Hi, no I do not have any smart home device or solar panel at my home. When my wifi network is password protected I believe no device should be able to join it without me personally putting the password. Would be interesting to know if anyone else had similar experience.

Yes to last question.

These modules are in so many devices that there is no way I can possibly guess which is it today.

There is a second issue here. I completed a call and the owner was upset that a device was showing in their WiFi hot spot lists. That is NOT A SECURITY BREACH as any device can announce itself.

They were adamant that they wanted it removed from the list which is only possible by turning off the power to the device.

So let's cover the only way a device can add itself without a password. That's the button on some routers to connect. Just disable that then change the password.

For me it was a Smart TV.

I found it to be a RCA Roku smart TV. (this was for my case)

Answer
Change Your Wifi Password

Change your Wifi password to block out any network that may have possibly gained access to your ASUS router. Also, note that Wifi routers can detect nearby networks that do not have access to your router but have SSIDs broadcasted. IoT devices often have their own wireless network. If other devices cannot access your router and network, they should not pose a threat to your network. Your Wifi network's name is also seen by routers nearby your router, too. Likely, the network name you noticed is from some nearby device.

E-reader?

In our case I just had the same thing pop up but then realized my son was downloading books on his kobo at the time and that is what the device was. Good luck!
