Desktop: PowerSpec G353
Router/Modem: AT&T U-verse Pace 5268AC Gateway Internet Wireless Modem Router
Motherboard: ASRock Fatal1ty Z390 Pro4
Power Supply: CoolerMaster Masterwatt Lite 600 Watt 80 Plus
Wifi Adapter: ASUS PCE-AC56 PCI Wireless Express Adapter
Operating System: Windows 10

My Macbook, LG V30, and iPad all get the expected ~110 Mbps up and down. My desktop usually gets 25-50 up/down over wireless. There are other times where the connection is so slow it can barely load a single webpage. The desktop is a gaming PC I bought a few months ago so it's all new hardware. My old NIC constantly dropped my wireless connection, so I bought this new ASUS one. Even with the old one, I don't think I was getting the speeds I should. Any help on troubleshooting?

I don't see an option to turn Bluetooth off within Windows 10 settings and I don't see it listed in device manager. No button shown in the action center either.

I have the ASUS utility installed for the wireless adapter. Configured for WPA2-Personal using AES.
