Review on 🔌 Enhanced Wireless AC 1200Mbps PCIE Wi-Fi Bluetooth Adapter - 2.4GHz 300Mbps or 5GHz 867Mbps - Windows Server, 7/8/8.1/10 (32/64bit) PCs - PCIE WiFi Bluetooth Card (FS-AC85BT) by Matt Jenkins

I used the built-in WiFi on my computer but it's not strong and the computer is on in the office. I installed this using the recommended Intel drivers. It's now 3x faster on download speed tests and 20% faster on uploads. However, I cannot view the 5G network (my phone sees it). Only works on 2.4G. My phone and wifi card that I tried earlier this week see 5G. I've tried uninstalling, deleting and reinstalling all Windows temp files and other files to no avail. I'll leave it because it's still much faster than the built-in one.
