I have a Power Spec B662 desktop computer. The motherboard is an AS Rock B250M-HDV. The operating system is Windows 10 home 64 bit Version 10.0.18363 Build 18363. The wireless network card is a Realtek 8812 AE Wireless Lan 802.11ac PCI-E NIC. It has given me problems from day one and I would like to replace it with a more reliable card. I have tried reinstalling the card and that does not fix the problem. What I am looking for is what type of network card do I need.
