2.5GBase-T PCIe 3.1 Network Adapter with Intel I225-V+3ft Cat8 Ethernet Cable 2500/1000/100Mbps PCI Express Gigabit Ethernet Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket

Easy install into a Dell Optiplex I converted into NAS. No compatibility issues. Good value

I purchased this NIC to bypass my motherboard’s integrated Realtek controller that was forcing my computer to be limited to 100mb/s network speeds. This NIC was very easy to install, and I was immediately able to see an improvement in speed as it auto negotiated true gigabit speeds with my switch. My ping dropped from 7 to 1ms, and streaming videos no longer freeze temporarily. Delivery was fast, and the contents were well protected. A great value for the money for the performance of this NIC.

DIED after two weeks. During its brief life it worked great. Guess I'll be spending a little extra money on something better. We had a lightning storm. I checked my computer devices to see if anything was damaged. Everything runs through an APC ups circuit protector. Everything is fine, however now the Network Adapter is working. Two weeks so far. I'll let you know if that changes. Spooky.

I've installed and uninstalled Intel Ethernet Adapter drivers v26.4 and v29.2 to no avail. I've even installed the Intel PROset software and couldn't detect the NIC. Item was DOA. It's my fault ultimately for not returning it within the original return period because I didn't test it initially (bought item originally for somebody who didn't need it anymore basically), but I wasn't expecting a non-working item either. I'm also not the only one who's experienced this based on some past reviews. This is my warning to everybody else now.

I recently made the jump to 2.5G and I upgraded most of the PCs in my house with these I225 based cards. They come with a normal PCI-E bracket as well as the low profile bracket for SFF PCs. It was plug and play for Windows 11, Linux, and FreeBSD.

My onboard network quit working. Used a x4 slot and it works perfect. Now I have 2 ports which my Synology uses. Easy setup and fast.

I tossed this NIC into an older Dell and built a pfSense (FreeBSD fork) firewall (IDS/IPS, domain blocking). This NIC functions well for this task and it was inexpensive to boot! It's a SFF Dell that found new life as the best firewall my SB client has ever owned. It's cheap, compatible and functions well. Pros: price, functionality, compatibility Cons: non existent for me at this time

Card installed and recognized by Windows 10, no special drivers necessary. System is also used for VMware work, ESXi 7 requires installing the Net-Community-Driver, current version is 1.2.7.0. Once that is installed, card is available for use and vMotion migrations are considerably faster than over a 1Gbit network.

This item works well in the SFF computer it is fitted to. I had to change over from the full height bracket to the low profile bracket (supplied in the box). The 2 screws holding on the bracket are an unusual head and do not fit a Philips or torx, etc. A small “screwdriver” is supplied but it has a very narrow handle and if a screw was stuck/tight, you would have a problem changing the bracket.

Ottimo, nel mondo Windows almeno!

Dia Karte funktioniert einwandfrei! Wurde rechtzeitig geliefert und macht dass was der manufacturer versprochen hat!

Fungerar EJ! köp INTE!! Tänkte uppgradera moderkortet från 1Gb/s till2,5Gb/s på en äldre dator. Det gick inte att köra detta kort med grafik kortet i datorn, endast med inbyggda grafiken på CPU! Dessutom fick Windows frispel, var tvungen att om registrera windows etc etc. Köpte ett TP link kort på 2,5 Gb/s som funkade direkt utan problem, så problem är det här kortet!!!

Lo mejor es que no es Realtek, por lo que va perfecto en Linux.
