Wireless N Dual Band 600Mbps (2.4GHz 300Mbps or 5GHz 300Mbps) PCI WiFi Adapter for Windows 11, 10, 8.x, 7, XP (32/64bit) and Windows Server Desktop PCs, PCI Interface WiFi Card (PCI-N600)

Very happy with this purchase.All I had to do was plug it in and it worked on my Linux system (Gigabyte motherboard)Good speed, too.

Works great with xubuntu as access point. Setup was a simple plug in and restart of xubuntu.

Llego a toda en 10 dias a Colombia. La tarjeta en una board g41 DDR2 con un Core 2 Quad y Windows 10 funcionó mejor de lo que esperaba... tengo 800megas de internet y en la red 5g me coge hasta 105megas... genial!!! con la anterior tarjeta en red 2.4g solo me cogía 15megas. Superrecomendada para combos antiguos.

Seems to work ‘ok’

Bought this because my PCIE slots are all used up. Router is on another floor, and still getting consistent connection. 100% would recommend

I got this card to use on a file server to transfer pictures, music, videos, etc. back and forth to everyone's computers in the house. I needed to put the server in a room away from any network connections and this card does the trick. I did not need super speed, and since this is an older pc with a lot of hard drives and space on the motherboard, it worked great. No issues with installation or range. If you are looking for the fastest speeds, this might not be the card you choose, but for most users, this will be great!

It established a 300Mbps link according to Windows, and I got it running transfers at about 120Mbps on 5GHz. Definitely beats a 54Mbps card for older systems that only have PCI available. If you don't know for sure that this is what you're looking for, then it probably isn't what you're looking for. This is an older technology card, on an older PCI interface, that supports older WiFi protocols. There aren't a lot of options for 802.11n cards on PCI though, so it doesn't feel right to be too picky. It is definitely faster than 802.11g, and it also means that you don't need to maintain a "g" network just to keep older gear running. I managed to move all of the frequently used systems to "n" or newer a little while back, so having a PCI "n" card is useful. I don't think I have seen any "ac" PCI cards, as all have been PCIe on either desktop or the little internal laptop cards. I also don't remember seeing PCI 450Mbps tri-antenna "n" cards. They might be out there, but I've not used one. So as it is, this is by far the fastest PCI WiFi version I have used. There is no driver CD in the box. The manual says that drivers are available on the FebSmart website, but the website driver page doesn't list any PCI network cards, let alone this specific one. Considering that most of the PCs that would be using PCI cards are old enough to not be using the newest operating systems, this is a considerable inconvenience.

Firstly, this is a PCI card, not a PCIe (PCI Express) card, which fits the older, usually-white, slots on older motherboards. Most new (~2015 or newer) desktops no longer have PCI slots. That said, this is a great upgrade for older computer that doesn't have any PCIe slots. If the desktop has a PCIe slot, it's usually much better to get a PCIe WiFi card, because there are WiFi 6e options for much better speed.What is interested about this card is that it is actually 2 cards! The PCI card is just an adapter from PCI to mPCI (mini PCI, which is not the same as mPCIe mini PCI express) with antenna breakouts, and in the mPCI slot is the actual Atheros mPCI WiFi card. I suppose if someone was adventurous enough and couldn't find any elsewhere, they could disassemble this and use the mPCI card to upgrade a much older mPCI laptop to get better WiFi. I might do this in the future...As for the performance, it works reliably. The antennas do a good job of getting a good signal, even at the back of a desktop surrounded by furniture, connecting at 300Mb/s and getting a decent ~50MB/s from desktop to NAS. Of course it's not as fast as wired, or the new wireless, but it's a substantial jump up from the little USB WiFi we used previously.
