Why Your Ubiquiti EFG Can't Push 25 Gbps Inter-VLAN — and What's Actually Going On

Or: How I Reproduced the Problem on x86, Tried to Load the Missing Modules on the Real Device, and What That Tells Us About Ubiquiti's Kernel

---

TL;DR

Ubiquiti markets the Enterprise Fortress Gateway (EFG) as a 25-gigabit-class router. The product page lists two 25 GbE SFP28 ports for WAN/LAN, and Ubiquiti positions the device as a flagship for medium and large enterprise deployments. Its silicon — a Marvell Octeon CN9670 — supports hardware-accelerated forwarding through purpose-built network engines (NIX) that should sustain tens of millions of packets per second. The UDM Beast, Ubiquiti's next-generation gateway, pairs a Marvell Octeon CN10K SoC (with ARM Neoverse N2 cores) with a dedicated Marvell Prestera-class switching ASIC accessed via PCIe — capabilities that, properly used, would offload most of the per-packet forwarding work into hardware.

Setting up Unifi Talk without Touch device

I recently came across the issue that I wanted to setup Unifi Talk but I didn't want to buy a talk device just to set it up (this was the recommended way from Unifi)

For Unifi Talk 4.2.4 its a little more difficult but still possible:

1. Go to your Unifi Talk setup page and press right mouse button -> Inspect
2. Go to Network tab in Dev Tools
3. Search for index-

Radxa Rock CM3 on a CM4 carrier board

Out of the box, the Radxa Rock CM3 does not work with boards designed for the Raspberry Pi CM4. Here are the steps to get the most functionlity working on a CM4 board.

Before we get started, if you appreciate the work I do with rpilocator.com, hwlocator.com, and dphacks.com, consider buying me a coffee.

Reverse Mouse Wheel scroll in Windows 11

Chose between natural mode like MacOS or Windows default mode.

Step 1: Open Windows PowerShell in Administrator Mode.

You can do this by going to Start Menu, type PowerShell, and click Run as Administrator.

Step 2: Copy the following code and paste it in the command line of Windows PowerShell:

$mode = Read-host "How do you like your mouse scroll (0 or 1)?"; Get-PnpDevice -Class Mouse -PresentOnly -Status OK | ForEach-Object { "$($_.Name): $($_.DeviceID)"; Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\$($_.DeviceID)\Device Parameters" -Name FlipFlopWheel -Value $mode; "+--- Value of FlipFlopWheel is set to " + (Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\$($_.DeviceID)\Device Parameters").FlipFlopWheel + "`n" }

Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

1. Verify driver support
