100M/1000M/2.5G NIC Network Card, Quad RJ-45 Port, with Realtek RTL8125BG Controller, Support Windows/Windows Server/Linux/Ubuntu/Centos/Vmware

I never really need wifi or bluetooth but having to use the pci slot for a 2.5gb card was annoying. This adapter freed up the slot and just gave new life to a bunch of boards. Perfect fit and detected by ubuntu and server 2022 without issue, getting 2.4gb+ speeds on downloads and file transfers.

Works very well in my Lenovo M715q tiny pc.

Very niche product that works for my very specific use case. I wanted to upgrade my Lenovo M700 Tiny with some higher speed networking as it has a DAS attached storage and Unraid on it.I was able to install it in the wireless card class that was close to the power button. The very tight fit, but was able to fold the cable under the card and route it to the back. I was able to pull the PCI brackets off the Ethernet port and use the screws and holes to attach it to an unused serial slot punch out. I used a piece of electrical tape to cover the bottom of the Ethernet port PCB to keep from shorts. It looks factory! Unraid 7.1.4 picked it up without any issue and able to see 2500 Mbps connection. (Router confirms as well) Initial speed tests seem to confirm it. Hopeful that the RTL8125 will be reliable as the Intel I219-V has been.Three complaints. First is on Amazon, the packed was crushed. Luckily it was packed in a strong plastic case. Second, the cable is very short. Even in my tiny client PC, it took some creative routing. I would appreciate a bit more length on the cable. Third, please include a screw for the M.2 please. I can understand a commodity SSD not including a screw, but this is a bit more niche. Even a cheap screw driver was included.Overall, a great way to add higher speed networking to a mini PC. Unraid worked out of the box.

Does not work with a Lenovo Thinkcentre M75q. Causes the PC to stall at boot. Removed the M.2and the PC booted just fine.

Plugged into my Windows 11 box. Worked as soon as it was booted without needing to click on anything at all. Delivers 2.5Gbps as advertised.

Motherboards Ethernet cord was extremely faulty. Put this in the pcie and haven’t worried about it since. Great connectivity works a charm!

Used it to have 2.5g on my Lenovo m910q Proxmox recognized it instantly. And it fit in the back with the included screws.

The card works, yet the connector between the M.2 card and the LAN socket can be connected wrongly as there is no marking to guide user (therefore 4 stars). Luckily there were no repercussions of performance after the connector was flipped to rectify wrong connection.Other than that - seems good product.In my case the I have returned the cards as I could not fit properly the cards in my Lenovo M90q.
