--- title: "Configuring network card settings in Windows 11" canonical: "https://help.vicon.com/space/Connect/1607823/Configuring%20network%20card%20settings%20in%20Windows%2011" format: markdown --- The following sections describe how to set up a network card in a Vicon system and may also help with troubleshooting connection issues. > ℹ️ **Note** > ℹ️ If your PC was supplied by Vicon, the network card settings are already optimized and you do not normally need to change them. > Macro (anchor) ## View the network ports The network ports and advanced network settings may not be visible until you install the network card driver. Note that these instructions assume that you are using Windows 11. If you are still using Windows 7, 8, or 10, see [Configuring network card settings in Windows 7 to 10](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1615585). > ✅ **Tip** > ✅ Before you install the latest version of the network card driver, uninstall any previous versions, using **Add/Remove Programs** or **Uninstall a Program from the Computer**. **To view the currently available ports:** 1. Open the ** Network Connections**. One way to do this is: 1. On the Windows taskbar, click Search and enter `Network Connections`. 2. Click **View network connections**. If Windows has not automatically installed the drivers, only the onboard (LAN) network port is visible: 2. If you can't see the other ports, install the relevant Intel Ethernet Server Adapter driver (go to [Intel® Ethernet Adapter Complete Driver Pack](https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html) to download the latest drivers), accepting all the default settings. The other ports are now visible: ## Configure advanced adapter settings After you have downloaded and installed the required drivers, and made the network ports visible in Windows, ensure the Advanced Adapter Settings are configured correctly. > ✅ **Tip** > ✅ If you have not set Windows Update to automatically check for updates, check for Windows updates before continuing. **To change the advanced adapter settings:** 1. Open the **Network Connections** window. 2. Right-click on the first network port and click **Properties**. 3. In the Properties dialog box, click **Configure** and then click on the **Advanced** tab. 4. In the Property list, ensure the following values are selected: 1. Click **Interrupt Moderation** and from the Value list, select **Disabled**. 2. Click **Interrupt Moderation Rate** and from the Value list, select **Off**. 3. > Macro (anchor) Click **Jumbo Packet**, and from the Value list, select **9014 Bytes** (ie, the maximum value): 4. Click **Maximum Number of RSS Queues** and from the Value list, select **8 Queues**. :warning: **Warning**: You can select more than eight RSS queues, however, this may cause problems. 5. Click **Receive Buffers** and from the Value list, enter the maximum value (**4096**): 6. Click **Receive Side Scaling** and from the Value list, select **Enabled**. 7. Click **Transmit Buffers** and from the Value list, enter the maximum value (this is usually **16384**). 5. Click **OK** to accept changes and exit. 6. Repeat the procedure for the other network ports. ## Identify and name ports To make it easy to identify the network ports, name them with the IP addresses that you will assign to them. **To identify and name ports:** 1. To see the currently available ports, open **Network Connections** (for a reminder of how to do this, see [View the network ports](#ViewNWPorts) ). 2. To identify the ports, begin by plugging a live network cable into a port and note its position (for simplicity, it may be easiest to choose the port on the far right or the far left). 3. Rename the identified port with the IP address you will assign to it: :check_mark: **Tip**: To rename a port in Windows 11, follow these steps: 1. Click on the name of the port to rename. 2. Click **Rename this connection** in the toolbar above the ports. 3. Rename the port. :check_mark: **Tip**: For Vicon video cameras, if your Vicon system already uses `192.168.10.1`, use the next address (`192.168.10.2`) for the network card instead of `192.168.10.1` shown above. Number the remaining ports consecutively (that is, `192.168.10.3`, `192.168.10.4` and `192.168.10.5`). For a table that lists commonly used IP addresses for Vicon systems, see [Standard Vicon system IP addresses](#IPAddresses). 4. Move the network cable to the next port. Network Connections displays a red X to indicate that the unplugged port is now not connected, and a new one becomes connected. 5. Enter the next IP address as the name of the second port: 6. Repeat for all the ports. > Macro (anchor) ## Assign an IP address to a port To assign the correct IP addresses to the ports, modify their network settings. **To change the settings on the ports:** 1. Open the ** Ethernet settings**. To do this is: 1. In the search bar next to the Windows icon, enter `Ethernet settings`. 2. Click **Ethernet settings** 2. In the **IP assignment** section, click **Edit**. 3. In the **Edit IP settings** dialog box, select **Manual** from the drop-down menu: 4. Click the **IPv4** toggle to set it to **On**. 5. In the **IP address** field, enter the main system IP address (the name you gave to this port, for example `192.168.10.1`) and in the **Subnet mask** field, enter the subnet mask (`255.255.255.0`) and click **Save**: 6. Repeat from step 1 of [Assign an IP address to a port](#AssignIPAddress) for the other network ports. > Macro (anchor) ### Standard Vicon system IP addresses The following table shows IP addresses that are commonly used in current Vicon systems (for 10G network cards): | **Device** | **IP Address** | | --- | --- | | Port for Vicon optical (main) | `192.168.10.1` | | Port for Vicon video 1–8 | `192.168.10.2` | For older Vicon system configurations that use i340 or i350 network cards, you may have additional ports that can be used for Vicon video cameras: | **Device** | **IP Address** | | --- | --- | | Main network card port | `192.168.10.1` | | Port for Vicon video 1 | `192.168.10.2` | | Port for Vicon video 2 | `192.168.10.3` | | Port for Vicon video 3 | `192.168.10.4` | | Port for Vicon video 4 | `192.168.10.5` | If you can't use the standard IP addresses (for example, because you're having to avoid a network conflict), see [Specifying the IP address for your Vicon software](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1605699). > ✅ **Link aggregation for multiple NICs** > ✅ In very large systems, to use more cameras or data, you can use additional NICs in your PC to split camera data. To do this: > ✅ > ✅ 1. Set the additional IP addresses of your NICs to different addresses in the available range 192.168.10.2–9. > ✅ 2. In your Vicon application software, in the Properties pane for each camera, set the **Destination IP Address** to the IP address of the NIC to which to send data. ## Check firewall and anti-virus software After you start your Vicon software, ensure that it is not blocked by a firewall and that it shows that the system is live. ### Change firewall settings If an alert similar to the following is displayed, you must change your firewall settings. ![image](media://c9d17703-52c2-4604-a82a-aa93f457f3c3) Do one of the following: - If possible, turn off the firewall entirely. -Or- > Macro (legacy-content) -Or- - If you don't have the necessary permissions to make these changes, contact your IT/IS department to obtain access. ### Disable or stop anti-virus software If you are still experiencing network issues, check whether or not any other anti-virus software is enabled that may scan the card traffic. Disable or stop this from scanning the cards used for the Vicon system. ## Troubleshooting - [No video data and gray camera icons](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1607823/Configuring+network+card+settings+in+Windows+11#NoVideo) - [Unable to use standard IP addresses](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1607823/Configuring+network+card+settings+in+Windows+11#NonStandardIPAd) > Macro (anchor) ### No video data and gray camera icons On starting your Vicon software, you may find that although the cameras appear to be fully controlled, video data is not displayed and the camera icons are gray. This indicates that the cameras are connected to the network but are not contributing data, which can be caused by jumbo packets being disabled in the NIC or switch. > ℹ️ **Note** > ℹ️ Switches purchased directly from Vicon are supplied with Jumbo Packets enabled. To resolve issues with non-contributing cameras: 1. Check that jumbo packets are enabled (see [Step 4c](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1607823/Configuring+network+card+settings+in+Windows+11#JumboPackets) in *Configure advanced adapter settings*). 2. Make sure that your network switch is not blocking them. For information on setting up your switch correctly, see [Configuring switch settings](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1608497). > Macro (anchor) ### Unable to use standard IP addresses Usually, the system IP address is set to `192.168.10.1` (see [Assign an IP address to a port](#AssignIPAddress)). If you need to use a different system IP address, for example, to avoid a network conflict, set the IP address as described in [Assign an IP address to a port](#AssignIPAddress), but specify the required IP address instead of `192.168.10.1`. Ensure the last octet of your IP address is from 1 to 9, for example, `10.0.0.1`. The standard system IP address (`192.168.10.1`) is used by your Vicon application software's executable file (*.*exe*) and by the shortcut that is automatically created when your Vicon software is installed or updated. To ensure your Vicon software uses the new IP address that you have set, you can: - Change the properties of the desktop shortcut for your Vicon application to specify the changed IP address. - Run your Vicon application software from the command line, enabling you to specify the IP address that it uses. For more information, see [Specifying the IP address for your Vicon software](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1605699).
