I live in a small two-story apartment. I have a decent ASUS Dual-Band 2x2 AC1300 router, and my main computer is upstairs. I want to use the 5GHz band because it is faster, and who doesn't want speed? I checked my Wi-Fi signal upstairs using a smartphone app, and I knew the signal was strong enough. However, after getting unsatisfactory results with a USB plug-in WiFi adapter, I decided to go the PCI route. I found this guy, and it runs like a dream. SpeedTest.net clocked my download speed at a blistering 118Mbps with my upload at 10.8Mbps (most internet providers have this 10:1 disparity between download and upload, and that is fine because that's what I paid for). Part of this good performance I can chalk up to the fact that both the Wi-Fi adapter and the Wi-Fi router are MU-MIMO so they can lock onto each other. But both devices have to work great to get the results I got. The magnetic antenna is a super nice touch, so you can attach it to any steel surface. It also comes with BluetoothOne caveat: The software comes on a CD, but it didn't work. It, in fact, caused my computer to seize up and I had to restart my computer manually! I ended up having to go to the Fenvi website, where I had to download a RAR file of the driver. Then, I had to download an extraction program that could unpack the RAR format. But, after all that, everything worked great.

I'm trying to set up an old desktop computer with Ubuntu to be an email/internet terminal, and don't have a wired network connection available. This fenvi card installed this easily in an older ASUS motherboard (M4A88TD-M/USB3). Ubuntu 20.04.1 LTS sees it from the installer, right out of the box. It was connected to our wlan before I'd even plugged in the antenna.Once I did plug in the antenna and ran a speedtest, I saw 294mbps bidirectional. Our service is 300mbps using AT&T's gateway, which is about 20' away through 2 plaster walls. By comparison, my phone w/ 802.11ac only gets 100mbps bidirectional, and my ancient laptop with 802.11n gets 70mbps up & 100mbps down. So I'd say the performance is there for sure.I've only had this working for a day. I haven't tried Bluetooth yet, nor any power features. The fenvi's already got me to my goal, so I'm pretty happy.

Worked out of the box when building a new Windows PC for a friend. Maintained about 400mbps of my network's 600mbps connection when near router with no interruption. Can't speak for higher speeds, range, or WiFi 6 due to my personal setup, but had no issues with my WiFi 5 network. Bluetooth seemed to work, although not tested for a long period of time.

My personal WiFi odyssey was a progression of OS changes. Namely, the change from Windows 10 -> Manjaro Linux -> Debian stable -> buying this card -> Debian 11 Bullseye (testing.) TL;DR, this card has confirmed compatibility with Debian 11. I'm still using it on an A/B/G/N router, so the AC/AX protocols went untested.My prior WiFi adapter was an Intel chipset that had a few reliability issues in Windows 10 with the adapter simply ceasing communication several times per hour. Those issues disappeared eventually, so I presume there was a background firmware update. When I got fed up with Windows hijacking my computer and making all my decisions for me, I eventually set up a dual boot with Manjaro Linux. The change was very refreshing, except that all my old WiFi issues came back threefold and made it very difficult to perform all those system updates in Manjaro. I read everything I could find about tweaking the config of the iwlwifi driver, but could find no suitable solution.I tried an OS switch to Debian 10 Buster (stable branch) because it didn't need to be updated constantly, and I thought the broader user base might have led to better WiFi solutions. Sadly, the latter was not true, and I suffered through it for a few weeks before I sought a hardware solution and settled on this Fenvi adapter. The product description here states that the Linux 5.0 kernel is required, which the stable branch of Debian didn't use, so I edited my repository config to point toward the testing branch that runs the proper kernel. It took hours on the old WiFi adapter, but I got everything updated before the Fenvi card arrived.After installing the new card, I booted into Debian testing, and without touching any driver config my WiFi worked! Speeds were commensurate with the old card's performance in Windows, which is good enough. I've been very happy with it. It's been a weird journey, and now I'm back to doing multiple dist-upgrades each week on Debian testing, but at least I've got the connection fidelity to handle it.
