In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking. Your LAN is essentially the network inside your home or business. In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind.
The link rate establishes how fast data can possibly be transferred across any given connection , but it does not guarantee how fast the hardware on either end of the connection will actually transfer data. The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
Following this chain, we see that Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is Mbps. A network interface represents connections, whether wired or wireless, that are made to form a network between devices. Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports".
Each network interface has 65, of these logical ports. Each port on a network interface is a separate data connection. Websites like speedtest. Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf. To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
To test a connection using iPerf, you'll need at least two network interfaces, and preferably two computers. You'll also need to know the IP Internet Protocol address assigned to each network interface. One network interface will function as an iPerf server, and the other network interface will function as an iPerf client. Lastly, you'll need to download the version of iPerf 3.
Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means. There's a lot more to networking that isn't covered in this article, but we hope this helps explain enough to get an accurate measure of your network performance.
If you need assistance with your Plugable product that features network connectivity, please contact us for further assistance. Whether you're on Windows, macOS, or Linux, it's common to add new audio devices to your computer. Here are the steps that you need to set a new default audio recording or output device on different operating systems.
Please see our pairing and configuration guide for Bluetooth devices. If no devices are connected to the USB ports within the Plugable UD, the green LED only lights up for around five seconds when the dock itself is connected to the upstream host system. If the included three foot long USB 3. The type of cable required is known as a USB 3.
An example of such a cable would this one. The power adapter included with the UD supports electrical voltages ranging from V, and electrical frequencies ranging from 50Hz and 60Hz. When purchased within in the U.
When purchased within Australia, the power adapter includes prongs for an Australian style power outlet. At this time we do not offer prongs for any other outlet style. That the blue power light blinks indicates the unit is not getting the power it needs to function properly.
The first things to check in that case are as follows:. The UD dock does not charge the host laptop. The laptop manufacturer's original power adapter must be connected to the laptop in order to charge the laptop when it is connected to the dock.
Windows has special power management settings that control what happens when the laptop lid is closed. If this happening, these settings need to be changed. The first thing to check if this happens is that the default audio playback device within Windows is set to 'Plugable Audio'. You can check and change this setting by clicking on the small 'speaker' icon located in the Windows taskbar 'task tray' in the lower right-hand corner of your desktop next to the date and time.
When you click on the speaker, a small pop-up window will appear and show you the present default audio playback device. If more than one audio option is available, you can click on the small upward facing arrow on the right-hand side of the list to expose all of the choices.
From within those choices, you just need to click on the option for 'Plugable Audio' to set it as the default. If have installed a previous version of the DisplayLink driver, please uninstall it and then reboot your system before proceeding.
Download the latest driver for macOS The Install DisplayLink Driver page will open. The system will need to be restarted when the installation is complete. The system should also prompt you to access the System Preferences to grant necessary permissions to the DisplayLink driver. Click to place a checkmark next to this entry.
The DisplayLink device should start working after the restart is complete. The disk image of the driver will mount, and automatically open the DisplayLink Installer main landing page. There is a chance that the security settings in macOS may block the installation of the DisplayLink extension.
A fresh installation must be performed to reset this timer. There is also a chance that the warning message about the blocked System Extension will not appear, but macOS may still block the extension. Double-click on the result. After a few moments the process will complete.
If your Windows laptop will not boot properly when a DisplayLink-based USB docking station is connected to the laptop, most often the cause is an external device connected to the docking station for example an external USB storage drive as opposed to the dock itself.
If you are affected by this condition, please follow these steps in order to isolate the behavior further:. In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports.
In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive. Since most external USB storage drives are not 'bootable', this can interrupt the boot process.
If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS also known as UEFI firmware to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option. Doing so helps ensure that the laptop will not try to boot from an external USB storage device.
Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer. Docking stations based on DisplayLink USB video technology are in essence a 'virtual' graphics adapter that relies on the host laptop's CPU and internal physical graphics processing unit aka as GPU to generate the information shown on the dock-attached displays.
The true root cause of this behavior can vary, and ultimately lies outside of the docking station or its associated DisplayLink driver. In some cases the root cause lies within the Windows driver for the host system's physical GPU and in rarer cases within the Windows operating system itself. This will allow us to examine some log files from your system to help determine the next steps. Please also include the Amazon Order ID number for the dock purchase. Anything I can try before asking for warranty support?
UD wont drive 3 monitors but Win10 sees all 3 displays. Hello and thank you for posting! To do so, please follow these steps: Please disconnect the dock from the system and please disconnect the power cable from the dock so it turns off completely this is important so the unit resets. Please keep everything disconnected until the last step. Now download and install the 9. Once the dock is powered on a blue light will be present on the front , reconnect it to your system.
Synopsis, Category, Audio Input and unbiased product. Universal Docking Station Docking Station pdf manual download. I have a Laptop and no external CD drive. The Plugable Technologies website has been online since Universal docking stations also let IT administrators standardize on one docking.
