I was really nervous about this card. The reviews are cause for concern. I installed it with some trepidation and tried to use the TP-Link Archer drivers from TP-Link's website, but they wouldn't install. They didnt detect a compatible card installed. I didnt have an optical drive handy to install the disk that came with the card, and was afraid to do so anyway based on the instability other users reported. So, I left it with the windows drivers, which I tried to update through device manager, but Windows already had the latest version it was aware of. First time I put the computer to sleep and resumed, the wifi connection was lost. I thought: here we go. But I then put the computer to sleep and resumed several times with no issues. And using speedtest, my wifi speeds were almost doubled from my previous speeds using the reasonably new wifi built into my MSI motherboard. The image I attached is from a speedtest through this card connected to my Linksys WRT1900ACS, which was pretty close to the computer. After a few days of running with the Windows drivers, I can say it seems to be pretty solid. I didnt quite see the speeds I hoped for, but I did see a big improvement over the previous wifi. Could I potentially increase my speed with better drivers? Sure. Probably. But based on the other reviews, it seems equally likely I might cause a major issue with my system, so will settle for good enough.

Works fantastically, it occasionally conks out when I am stress testing my GPU and the nearby heat gets too intense for it. However this is more the fault of my microatx motherboard's compact space management. I would recommend getting the B450M DS3H WIFI (rev. 1.0) to avoid any airflow impedence and space management issues on this microatx motherboard.

Worked great for a bit, now i am getting drops in my internet. I have tried a few things, that helped make the issue less frequent but have not been able to fully solve my issue. I will be disconnected from the internet, but once i run a trouble shoot i will be reconnected. Amazon supplier got back right away, but only to tell me to contact their main tech support, which i did... yet still haven't heard back from them though its been nearly a week. When the issue isnt there the connection is fast and stable. Not sure what the problem is, but when you are playing a multiplayer game and get disconnected it really gets really annoying

I think I'm an outlier for this review... my router is unreliable and doesn't provide a constant stable connection. Aside from that, I made the switch from Linksys T8E Archer because the new Win10 update didn't support the device even though it could detect 5ghz wifi. Not sure why Microsoft does this. This card always has a strong signal and is far cheaper than what other competitions offer. Definitely recommend if you are building a decent workstation/gaming rig.

Bought on Dec 15 after reading reviews. Dec 17 I received and gave to my son for his computer, Jan 15 wifi wasn't working. Kept losing speed and connection. Checked and rechecked everything isp, updates, trouble shoot and computer configurations and checked there website for help. Bought a cheap usb wifi worked 100% better. Could just be this one from reviews I read but I am 1 chance person with all the technology out there. Not buying any rosewill products anymore.

I didn't read the compatible OS list and I didn't read that it only supported Windows only. I use Linux for everything but go into Windows for gaming. So don't get this if you intend to use it for a Linux machine. If you're getting it for a machine running Windows, go right ahead. 5/5, I just made a rookie mistake.

When booting your PC for the first time for the day it does not connect to any wifi network. Tried reinstalling the driver and changing the PCIE slot but the issue persists. Only way to connect to the wifi is to reboot and it will automatically connect.

Got this card to replace my old wifi card. First few days were good, then problem started. It wouldn't connect to my router or simply just drop the connection after a few minutes. This is happening everyday... Do not buy this card!!!
