Dual Port Gigabit Ethernet Converged PCI-E x1 Card,2X RJ45 Gigabit Network Interface Controller Adapter,with 82575EB Chipset for Desktops,Work Stations,Servers, with Low Profile Bracket.

Installed this in a workstation PC in order to convert it into a pfsense router, has been working perfectly for over a month without any signal issues.

Plumbed to a PfSense firewall vm.. working great! 👍

Used this card in an older Dell Optiplex that I wanted to turn into a firewall. Loaded pfsense firewall and card was recognized during install. Working great one port LAN one port WAN.

works perfectly

internet thought put went from ~105mb down to around 326mb down!

I'm going to be candid with everyone about this review. I had an serious computer/power supply malfunction immediately after installing this card, which led to my computer having a BSOD (blue screen of death). However, I cannot honestly and truly without a doubt say that installing this card was the reason it happened. I'm sorry to the seller if it wasn't, but I have to be honest about my experience and why I have come to this deduction. I installed this dual Ethernet card into my PCI express port on my motherboard, turned on my computer one time after installing it, used my computer for about 30-60 minutes. During this time I mostly browsed the internet, did speed testing, looked around in the adapters driver configuration options and that's about it. After I decided to go get another project done around the house, I fully powered down my computer and walked away. I own a HP 8300 CMT, with a Intel i7 3rd generation vPRO. When I came back to use my computer a few hours later, the power light on front of my computer was blinking red. Upon pushing power button, fans spun for a second or two and shutdown. Red light blinking about 3 times with a pause in between. So, the fear and worry set in which led to A LOT of troubleshooting. I have a 750W Thermal take power supply which is pretty old, but worked without any problems. In order to get my computer to even turn on, after trying the usual simple troubleshooting steps. Such as, unplug power supply, hold power button for x amount of time, removing all peripheral devices, including my graphics card EVGA GTX 770 SC, this network card, usb receiver for keyboard and mouse, etc. No luck. So I swapped out my power supply with the OEM one and removed the cmos battery. (Resetting my CMOS/BIOS is what I believe made the problem worse for me in the end) Finally, my device powered on, hooked up to vga monitor. I have a Power on Password, Secure Boot, TPM module, BIOS set to disallow PXE, WoL, NO AMT/ME enabled. My TPM was set to Virtualization On and all additional settings for VT except TxT, OS managing my TPM and No PPI enabled. I believe due to my TPM and secure boot I caused the BSOD by resetting BIOS/Etc., However, I believe the new peripheral device(not the first I have connected to my motherboard in the last month) was directly responsible for the red light and no boot situation which led up to it. Again let me repeat I can not say it was definitely related to a fault in this Ethernet card. However, with my bios settings, my 3rd generation legacy Intel vPRO i7, the TPM and secure boot, I believe it caused a fatal error where other cards plugged into same PCI express port did not. I am on the fence now about keeping this card and will probably return it because 2 days of trying to resolve my BSOD without reinstalling windows and now being wery of another power supply failure or even worse possibly my graphics card.... I just can't take that risk. I tried to provide as much honest information about what happened so that others can make their own decision and also so others can learn from my mistake with Secure Boot, TPM, etc and resetting BIOS via CMOS battery removal or CMOS reset button. I tired windows auto repair, command prompt bcedit, chkdsk, sfcscan, diskpart, boot in with safe mode(which only appeared as an option once) and I got into windows. My windows account password would not log me in for back up, recovery at all. Even though it was correct. (Probably due to TPM and OS not being able to exchange key IDs) How I solved my issue: I had over provisioned my Samsung 860 EVO 500GB SSD by 10%, which allowed me to install Win 10 with USB iso on the unallocated space. Disabled Secure boot, TPM, Drive Lock, Allowed legacy devices (just in case). Then was able to access my files on partition 3 within Windows. If you do not have any unallocated space for installation of Windows, either command line diskpart to shrink you system partition if space is available. Or use external USB hard drive enclosure on another computer to retrieve files. Or use another form of bootable USB media like GParted, Clonezilla, etc. To clone HDD or resize partitioning for another separate windows to boot to. ***Only applies of you have BSOD that was unable to be resolved due to a ACPI.Sys error. Hope this review is helpful to someone in any way. PS: The dual Ethernet card came in bubble wrap in generic box. No antistatic bag and the Ethernet chip is covered by heatsink, so you can't be sure if it is what it is, prior to install.

Bought this because the built-in adapter on my home-built low-power NAS server would freeze up if I performed a send/receive copy via an attached PC: i.e the built-in could not reliably handle full-speed full-duplex IO. This one was immediately found in FreeBSD 12.2. It improved performance a little, and has had no problems with a send/receive copy of large data sets. Could not have been an easier upgrade. Card quality looked to be top notch even though it came in a formed plastic box in a bag. I’m only using one of the two ports, and think that it would also work great in a firewall computer system built upon OPNSense or pfSense. Very happy with this purchase and I'd purchase another. (Two weeks later) I just purchased a second one for my OPNSense firewall. This one came in a nice production type box. Both my systems FreeBSD based, so again this card worked directly. I would definitely consider any other cards produced by this manufacturer.

This NIC worked immediate on my NAS without a problem. My NAS gives speeds till 116 MB/s, what is close enough for me to the theoretical 125 MB/s or 1 Gb/s. This NIC does what it needs to do and keeps working. The onboard Realtek NIC gave the same speed but stopped working or freezes randomly while transferring big files.

using it to split my network into two LANS. IOT and MAIN in pfSense. pfSense is running inside a VM on an esxi server. This card is on that esxi server. In other words it works great in esxi and pfSense. Gigabit speed from both ports. Recommended.

I was able to turn an older PC into a pfSense router with the addition of this NIC
