NIC Teaming for Windows 10 Support Works as intended.
NIC Teaming for Windows 10 Support Works as intended.
Hi everyone, I managed to activate teaming across several NIC cards by entering a specific command in Windows PowerShell. This was done on a Windows 10 Pro 1809 Build (x64). The command I used was: New-NetSwitchTeam -Name "SwitchTeam01" -TeamMembers "Ethernet","Ethernet 2", "Ethernet 3". I changed the names to reflect the teaming of multiple NICs instead of just using generic terms like "Ethernet". Earlier, I attempted commands such as New-NetLbfoTeam and New-NetLbfoTeam with team members "NIC1","NIC2" and tried setting teaming mode to LACP, but those didn’t work. The error message indicated that LBFO wasn’t enabled or wasn’t supported for this model. I learned that LBFO isn’t available in Windows 10 SKUs but is present in Windows Server. Another method was using the Intel Network Connections app to enable teaming, though I didn’t have an Intel card. To fix this, I removed the drivers and reinstalled my Realteck NIC with the latest updates. After verifying the network properties, I installed the required driver and ran the teaming command. This allowed me to create a teamed adapter visible in the Control Panel, which improved my internet speed to 3Gb/s. * Keep in mind I removed my DNS name and both IPv4 and IPv6 addresses for privacy. If you follow these steps, you should achieve similar results.* Also, the red box indicates the current connection speed of the adapter, which can be used for virtual machines in Hyper-V. However, if you want distinct IP addresses per card, avoid this approach as it won’t support individual assignments.
This 3Gb/s speed is likely intended for testing purposes to demonstrate capability, or it could be used to transfer files more efficiently on your local network.
It's primarily designed to speed up file transfers across my network while also providing redundancy in case of failures. This approach also improves my connection to VM resources remotely, giving me better local data speeds for applications I run locally. With my current setup, I have a 1Gb/s fiber-optic internet connection, which supports external users connecting via VPN and servers more efficiently, reducing latency to under 7ms. This means accessing large files, system backups, or running graphics-heavy apps on the VM becomes much smoother with minimal network delay. I’m currently using a standard 1Gb/s NIC, but upgrading to 10Gb/s or fiber-optic cards would further boost bandwidth and speeds between servers, media systems, backup servers, remote hosts, clients, VMs, and storage solutions.
You're encountering issues with the New-NetSwitchTeam command on Windows 10 1809. The error suggests the LBFO feature isn't enabled or isn't supported for your SKU. You've already installed the Realtek Teaming Protocol Driver (NDIS 6.40), but the command fails with a parameter mismatch. Try verifying driver compatibility, updating the driver to the latest version, and ensuring you're using the correct team members format. If problems persist, check Microsoft support documentation for Windows 10 1809 regarding LBFO requirements.
Hi Dantech, could you share a screenshot of the "Network Adapters" form in Device Manager and the Network Connections form under Control Panel? Then select "Change Adapter Settings". Regarding the code: New-NetSwitchTeam -Name "SwitchTeam01" -TeamMembers "Ethernet","Ethernet 2", "Ethernet 3". Please run this as an administrator in Windows PowerShell. The switch team name should match the NIC team you specify. Ensure the five Ethernet adapters listed are real physical devices—not virtual ones—otherwise consider setting up a network bridge. Also, avoid creating a team for a NIC that’s already assigned to a virtual switch. Best regards, Paul
Hello, thank you for your message. The screenshots you shared show the onboard NIC from your motherboard and a RTL8111G with four gigabit ports connected via PCIe. I tried both with and without the VM software installed. If I connect the NICs through bridging, do I still achieve the same performance? You mentioned aiming for 5Gbps LAN communication to a server using the same PCIe NIC and one onboard Windows Server 2019 instance, successfully implementing NIC teaming.
Hi Dantech, connecting the network adapter should produce the same outcome, though I’m not entirely confident about it. Based on your images, I’m struggling to identify the problem... I’m unsure if checking the RTL8111G NIC on another machine would help verify functionality. Additionally, you might want to uninstall all drivers linked to the NIC and retry the process without installing any new ones. Follow these steps: 1. Open Device Manager 2. Pick a Realtek PCIe GBE Family Controller 3. Click the "X" button at the top labeled "Uninstall Device". 4. Repeat this for each NIC, including your onboard one. 5. Click the "search of hardware" icon. 6. Attempt the PowerShell instructions once more. Let me know if that resolves the issue. Best regards, Paul
Thanks for your input. I haven't tried it yet since I'm new to teaming. Regarding your questions: Hyper-V needs to be enabled before you can use this feature. If the teaming doesn't work, you can remove the network switch using the command `Remove-NetSwitchTeam -Name "x"`. For more details on enabling Hyper-V, check the official documentation here: https://docs.microsoft.com/en-us/virtual...le-hyper-v
I attempted this setup. The network shows 2gbps, but I'm using just two NICs for teaming. I also enabled LAG on those ports on my Netgear gt784ts switch, though it doesn't function properly. When I tried simultaneous 1Gbps transfers, the speed dropped to around 970Mbps, effectively halving the performance between the two devices. Anyone have experience with this configuration and seen positive results?
