1Gb PCI-E NIC Network Card for Broadcom BCM5751-1P,10Mb/100Mb/1GbE Copper Single RJ45 Port, with Broadcom BCM5751 Chip,1GbE PCI Express 2.0 X1 Ethernet Adapter Support Windows/Linux/VMware

The thing to know about this card is it supports multiple speeds. I had a router I built that had a card with the X540 chip in it. The issue is that the X540 only supports 100Mbps, 1000Mbps, and 10Gbps. This card supports 2.5Gbps and 5Gbps. That is something that is important when setting up your network for multi-gigabit. Do yourself a favor and just spend the extra money for this card. Works great with OPNsense, just have to manually set the speed.

Bought this to replace a dead ethernet port on my motherboard. I liked the fact that this model had a heatsink since heat can can induce thermal throttling for these types of things and in terms of a network adapter, that will affect the transfer speeds (i.e. reviews complaining about thermal throttling for USB network adapters).Also it was cheap enough that I wouldn't feel too bad if it didn't work. A few months later after installing and it's still going strong. I get sustained 2.5gbe speeds out of it transferring files within my network to and from my server so I can't really complain.Only minor negative I can think of is it has a bright red activity light that constantly flashes on the inside of your case. This is a problem if you have a windowed side panel like I do. Not a deal breaker and can be addressed, but annoying nonetheless.

This review is mainly as a new Verizon FIOS customer, subscribed to 500/500 plan. My motherboard has Intel I211 Gigabit Ethernet onboard. My download speeds were on point. My upload though was atrocious. Like ~20 Mbps upload atrocious. Read reviews about making settings changes to onboard Intel Ethernet through Device Manager on Windows 10 due to a bug that Intel has on their chips. That didn't help. Then I read about getting a Realtek NIC. Got this Vogzone Realtek NIC since it was low cost, easy install, downloaded drivers from Realtek directly and installed them. For added measure, I went into the advanced settings for the Realtek NIC through Device Manager, disabled "Energy Efficient Ethernet" and "Green Ethernet". I also set "WOL & Shutdown Link Speed" to "Not Speed Down". Rebooted the Verizon FIOS router, and I have finally achieved the speeds I am paying for (see attached image).

Very cheap card that does what it's supposed to (which is to transfer data faster than a 1gb nic).I haven't saturated the full 2.5gb speed, due to the slow hard-drives in my server, but it definitely gets at least 1.5gb throughput.I bought a pair of these, one for my primary PC, and one for my linux server (running Amahi based on Fedora 19), with them connected via a 2.5gb managed switch.Install in Windows 10 was literally just "plug and play". Plugged it in, let windows boot, and it worked right away.Install in my linux server was another matter, but that's predominantly due to the older version of Fedora.The linux drivers can be downloaded online, and they may already be included in newer linux distros.I couldn't install the precompiled drivers since they didn't have a variant suitable for Fedora 19, so I downloaded the drivers from https://github.com/awesometic/realtek-r8125-dkmsThe autorun.sh didn't work for my distro, and in fact froze-up my server, so I went the DKMS path. I then found that I couldn't compile the drivers because I was on a minor rev of Fedora 19 and there were no headers available for a matching version, so the build complained, so I updated my server to the next fullt supported release with headers (without doing a major update), and tried again.However, I found that since Fedora 19 is based on a now relatively old linux release, and the driver code had been updated for new linux releases, that there were build errors when building against the kernel headers for Fedora 19.Fortunately, being a software engineer/architect by trade, it was a relatively easy fix. There was an unnecessary header file include, and another error that I was able to easily work around. I'll try to submit my changes back to github and make a pull-request, since there's no real reason the driver can't also support older distros.After those couple of fixes I was able to build the drivers, and install, without issue, and the card has been working well since.I'll actually be upgrading my server soon, and although the new motherboard will have a 2.5gb NIC built-in I may try to use this card in tandem, and run them trunked together. The server will be switched to TrueNAS (based on OpenBSD) and if I do decide to use this card on that system then I'll update this review if I run into any issues.

One of the few 10GB variations that works natively in Proxmox. I bought 3 of these.

Card arrived. Turn off computer. Put the card. Turn on computer. Open network setting window. Switch the Ethernet cable from the old port on motherboard to the one on this card. Watched the network connected. Checked status. Speed is 2.5G.Hope the card lasts.

Installation went smoothly. Worked OK initially but failed suddenly after a few days of use. Returned defective unit.

Worked as expected, but if using in a home theater with a transparent case, you will see the bright lights for the connectivity, etc.

Works out of the box with my 12 year old intel workstation motherboard, with a truenas setup. Negotiates nicely with my 10gig sfp+ zyxel switch. Options in India are very expensive online, this was still reasonable compared to everything else out there.

Works perfect on HP Z8, install intel drivers for windows 10
