If you find that your Plugable ethernet adapter or docking station is not connecting to the internet or is experiencing slower than expected speeds on your Mac then it may be related to its position in the macOS Network Service Order. This can apply to your Wi-Fi connection, ethernet, and even NAS systems.

macOS attempts to connect to the internet using the network service at the top of your list first. If your Wi-Fi or NAS (Network Attached Storage) is listed above your Plugable ethernet adapter, this often leads to users unknowingly using a slower wireless connection when they intended to use a wired one.

To ensure you are getting the full speed and stability of your wired connection, you must prioritize the Plugable ethernet adapter above Wi-Fi.

Navigate through these steps to Set Service Order:

1. Click the Apple Menu () in the top-left corner of your screen and select System Settings.
2. In the sidebar, click Network. 
   1. 
3. Look for the Action Menu (a circle with three dots ...) located at the bottom right of the main window area.
   1. 
4. Click the three dots and select Set Service Order.…
5. A list will appear showing all your network interfaces. Click and drag your Ethernet Adapter (often named "USB 10/100/1G/2.5G LAN" or “Plugable Docking Station”) to the very top of the list, above Wi-Fi.
   1. 
6. Click OK to save your changes.

Your network traffic will now automatically prioritize the wired connection, ensuring you receive the best possible speeds and stability from your Plugable adapter.

One helpful way to identify your ethernet link rate speed is through the System Settings app in macOS. This can help us identify if your Plugable ethernet adapter is negotiating either 1Gbps or 2.5Gbps network speeds. Some routers have a mix of 1Gbps or 2.5Gbps ports, and in the macOS System Settings this will be shown in the Speed field. 

In this example, we will be analyzing our USBC-E2500, which is a 2.5Gbps ethernet adapter. This method applies to all of our ethernet adapters, such as:

• USB3-E1000
• USBC-E1000
• USBC-E2500
• USBC-E2500PD

Navigate to the Network section, select the entry named “USB 10/100/1G/2.5G LAN” with the Green - Connected icon. Expand the Details button, and go to Hardware.

If you're looking to upgrade your wired or wireless network speed and internet connection with a Plugable USB network adapter, you’ll want to make sure you pick the right one for your setup. The three key factors to consider are:

1. The type of network you are connecting to: Wired or Wireless (Wi-Fi)
2. The type of USB port on your computer (USB-A, USB-C, or Thunderbolt)
3. The Ethernet speed you need (Gigabit, 2.5 Gigabit, 5Gbps, or Wi-Fi)

This guide will help you quickly determine which Plugable adapter best fits your needs.

Step 1: Identify Your USB Port Type

Different Plugable adapters are designed for different USB connections. Here's how to find out what type of USB port your computer has:

• USB-A Port (Rectangular Shape) – Found on most older and some newer PCs and laptops. If your device has standard USB ports, you'll want an adapter with a USB-A connector.
• USB-C Port (Small, Oval Shape) – Found on modern laptops, tablets, and some desktops. If your computer has a USB-C or Thunderbolt 3/4 port, a USB-C adapter is a better choice.
• Thunderbolt 3 or 4 – Thunderbolt ports support USB-C accessories, so any Plugable USB-C Ethernet adapter will work.

💡 Not sure which ports your computer has? Check the manufacturer's website or look for an icon next to the port: a Lightning bolt indicates Thunderbolt ( or charging ) while a USB logo will indicate the USB version.

Step 2: Determine the Ethernet Speed You Need

Your network speed is influenced by both your internet plan and the devices on your network. Choose an adapter based on the speed you want to achieve:

💡 Check your router’s specifications to see if it supports higher speeds like 2.5Gbps before choosing a multi-gig adapter.

Step 3: Choose the Right Adapter for Your System

Now that you know your USB port type and Ethernet speed requirements, here’s a quick guide to help you select the right Plugable adapter. The best bet is to meet or exceed the internet service provider’s rated speed, or for local file transfers the speed of the other systems on the network. For example, say your ISP provides a 2Gbps internet connection, then a 2.5Gbps or 5Gbps Ethernet adapter will be a good fit, while a 1Gbps adapter will still enable internet connectivity, the maximum data rate would be limited to 50% that of the rated internet speed.

For USB-A Computers

✅ Need basic 100Mbps Ethernet? → Choose the USB2-E100
✅ Need Gigabit speeds? → Choose the USB3-E1000
✅ Need Wireless Connectivity → Choose the USB-WIFINT

For USB-C or Thunderbolt 3/4 Computers

✅ Need Gigabit speeds? → Choose the USBC-E1000
✅ Need 2.5Gbps speeds? → Choose the USBC-E2500
✅ Need 5Gbps speeds? → Choose the USBC-E5000

Frequently Asked Questions (FAQs)

Q: Can I use a USB 3.0 Ethernet adapter in a USB 2.0 port?

A: Yes, but it will be limited to USB 2.0 speeds, which may affect performance.

Q: Will these adapters work with macOS, Windows, and Linux?

A: For the most part yes, except for our USB-WIFINT relies on proprietary drivers and is not recommended for macOS, Linux, or ChromeOS systems

Q: Does a faster Ethernet adapter make my internet speed faster?

A: Only if your internet service provider (ISP) plan supports higher speeds. A 2.5Gbps adapter won’t improve speeds on a 1Gbps internet connection.

Q: Can I use a USB-C adapter with a USB-A computer using an adapter?

A: It depends. Some USB-C to USB-A adapters may work, but some are limited to USB 2.0 data rates and can affect the network performance. When possible we recommend using a native USB-A Ethernet adapter for most reliable performance.

Conclusion

Picking the right Plugable USB to Ethernet adapter comes down to knowing your USB port type and the speed you need. Whether you’re looking for a basic 100Mbps connection or blazing-fast 5Gbps speeds, Plugable has an adapter to keep you connected.

What is the MAC address?

The MAC address (Medium Access Control address) is a unique network address for each Network Interface Controller to identify the hardware on the network segment. The address is generally expressed as six hexadecimal digits, sometimes separated by a '-', ':', or without a separator.

The MAC address is assigned by the hardware manufacturer during production, however many network controllers allow the operating system (via the drivers) to override the MAC address, this is handled at the operating system level and does not change the address stored in the adapter.

The first three octets (first three hexadecimal values, six characters) identify the network hardware manufacturer while the last three octets should be unique within each hardware manufacturer's product line. For example Plugable's MAC addresses all begin with "8CAE4C", with lower values typically representing older companies, "000000" belongs to Xerox for example, some companies have multiple ranges of MAC addresses.

Why it can be useful to override the manufacturer's address?

Setting a custom MAC address can provide anonymity when connecting to public networks. It can also be used by an IT Network Administrator to provide specific access rights to computers based on the connection.

It can also be useful for Network Administrators for testing, troubleshooting, and maintenance to simulate different devices without having access to that specific device.

Changing the Mac Address in Windows

The MAC address can be manually set from the Device Manager:

1. Right-click on the Start Menu and select Device Manager from the pop-up window

2. Expand the Network adapters section and double-click on the network adapter to be modified

3. From the network adapter properties pop-up window, select the Advanced tab

4. Under the Property: category, scroll down to and select "Network Address"

5. In the Value: field, enter the new MAC Address in hexadecimal format, the field has a maximum of 12 characters so do not use any separators between octets

6. Select the OK button to proceed

You can also check the MAC Address from the command line

1. Right-click on the Start Menu and select Terminal or Windows PowerShell

2. Type in the following command ipconfig /all or ipconfig /all | findstr C:/"Physical Address" to filter just the Physical Address lines.

3. Scroll through the output to find the target network adapter and Physical Address

Checking the MAC Address in Linux

The MAC Address can be checked from the terminal:

1. Open a bash shell

2. Read the address from the /sys directory:

cat /sys/class/net//address

or from the ip command to print out all of the hardware MAC Addresses

ip -o link | awk '$2 != "lo:" {print $2, $17}'

Changing the MAC Address in Linux

Temporary change until system reboot

1. Open a bash shell

2. Run the following command to set the MAC Address for a specific network device.

sudo ip link set dev <devicename> down
sudo ip link set dev <devicename> address <mac address>
sudo ip link set dev <devicename> up

3. Confirm the new MAC address

Permanently change the MAC Address

This can depend on your distribution's specific network services and settings. This example will create a new systemd unit file to change the MAC Address on startup.

1. Open a bash shell

2. Create a new systemd unit file "/etc/systemd/system/changemac@.service with the following contents the mac address should be colon separated:

[Unit]
Description=Change MAC Address %i
Wants=network-pre.target
Before=network-pre.target

[Service]
Type=oneshot
ExecStart=/usr/bin/ip link set dev %i down
ExecStart=/usr/bin/ip link set dev %i address <mac address>
ExecStart=/usr/bin/ip link set dev %i up
RemainAfterExit=yes
User=root

[Install]
wantedBy=multi-user.target

3. Enable the service with the following command

sudo systemctl enable --now changemac@<interface_name>

4. Reboot the computer, the MAC address should be set to the new address
