I have a Netgear Nighthawk router that I use for gaming and connect devices that need quick access to the internet, like my alarm system and IP camera setup.
One day, when I was browsing through the app, I noticed that there was an unknown device named Shenzhen Bilian Electronic among the list of devices.

I don’t remember owning anything from that brand; how could I? I’ve never even heard of them before.
My neighbors had reported that someone was using their Wi-Fi without their permission, so I wanted to find out if that’s what was happening here.
I logged on to the internet and went far and wide to know what this strange device is, and to know for sure if it was malicious or not.
I read through many forum posts and the technical manuals for the devices I connected to the Nighthawk router to get to the bottom of this.
With the help of all the information that I gathered, I managed to make a guide that should help you find out what this device is doing on your network and if removing it is required.
The Shenzhen Bilian Electronic device on your Wi-Fi is probably one of the IP cameras you can watch through an app on your phone.
Read on to find out how to check if the devices on your network are malicious and how you can secure your Wi-Fi network better.
What Is A Shenzhen Bilian Electronic Device?
Shenzhen Bilian Electronic Co. is a component manufacturer that makes wireless communication equipment for industry leaders like Realtek and Broadcom.
Their other products include ethernet switches, internal wireless routers, wireless card modules, and a whole lot more.
The bigger companies outsource smaller component manufacturers to companies like Shenzhen Bilian Electronic Co to keep their final consumer costs low.
You may not have heard of this company because they don’t sell products to you, the customer.
Its clients are all other businesses that contract them to make chips for them.
As a result, you will see components that Shenzhen Bilian Electronic Co makes in a lot of products that have Wi-Fi connectivity.
Why Do I See A Shenzhen Bilian Electronic Device Connected To My Network?
Since Shenzhen Bilian Electronic Co. makes components for many big-name brands, the chances are that some of the devices you own might have a network card that they made.
When these cards talk to your Wi-Fi, they should report themselves as the product they are on, but sometimes because of how your router handles device IDs, it may show up on your network as a Shenzhen Bilian Electronic device instead.

The chances are that one of the devices that you own uses one of their network cards to enable it to connect to your Wi-Fi or home network.
This isn’t just limited to Wi-Fi, though; you might also see this device if it was connected to your router with an Ethernet cable.
In the rare chance that you don’t own any device that has a Shenzhen Bilian Electronic Co network card, you can follow the steps that I’ll be talking about later in the article to secure your network.
But the chances of this being true is slim, so rest assured that this device is just one that you own.
Is It Malicious?
You will only need to worry about the Shenzhen Bilian Electronic device on your network if it’s not from a device you own.
Attackers rarely feel the need to disguise themselves as a legitimate device because doing so might not be worth the hassle.
Ninety-nine percent of the time, the Shenzhen Bilian Electronic Co device would be one of your own and was just a case of misidentification.
If you found it to be malicious, there are a few ways to remove the device from your network.
Securing your network is pretty important, and having a proactive approach when doing so, can help you in the long run.
To find out if the device is one you own, pull up the list of connected devices that you saw the device in.
Turn off each device you have connected to your network, and check back with the list every time you turn a device off.
When the Shenzhen Bilian Electronic device disappears, the device that you last took off the network is the misidentified device.
If you went through the whole list, but the device didn’t go away, you should start securing your network.
Common Devices That Identify As Shenzhen Bilian Electronic For Wi-Fi
Identifying which device the Shenzhen Bilian Electronic device isn’t straightforward since they don’t have any outward branding that you can easily see.
But a few devices commonly use network cards from Shenzhen Bilian Electronic Co that make it pretty easy for you to identify the device.
The most common device that uses network cards from Shenzhen Bilian Electronic Co is IP security cameras.
They need to be connected to NVRs that are part of your system, as well as your phone, to watch the camera feeds on it.

To make this happen, they use network cards to connect to your Wi-Fi network, where the cameras can find your NVRs.
The app you use to control your NVR camera needs the network card to communicate with the camera over Wi-Fi.
How To Secure Your Network
Even if you think your network is secure, it pays to be one step ahead of the regular security and set up an extra few defenses against potential threats.
To secure your network:
- Change your Wi-Fi password to something stronger. You can change your password by going to your router’s admin tool.
- Set up MAC address filtering on your router. It sets up an allow list for only the devices you own and blocks other devices from connecting to your network.
- If your router has a WPS feature, turn it off. WPS is known to be pretty unsecure by today’s standards.
- Use a guest network for people who want to temporarily use your Wi-Fi network. Guest networks are isolated from the main network and can protect your devices from being accessed without authorization.
Refer to the manual for your router to see how to set up these features.
No router has the same procedure, and it would be easier to refer to the manual and be absolutely sure of what to do.
Final Thoughts
Shenzhen Bilian is a pretty popular manufacturer among big brands that sell products to you like Realtek and Broadcom.
Other companies also manufacture network cards, like Foxconn, but they aren’t immune to being misidentified as well.
The products that Foxconn manufactures, like the Sony PS4, also get identified differently; they show up as HonHaiPr on a list of connected devices.
The issue there is the same; it’s just that the router thinks the network card vendor is the device’s name.
In both cases, there’s nothing to worry about.
