AC 3165 brings down entire WiFi network for the house?

Hello everyone, I have a laptop using the wireless AC 3165 network card, and I have successfully updated it to the newest version, 19.51.5.3 (Driver date 8/3/2017), this has fixed many problems for me, but a few problems still linger. If anyone has any insight that would be appreciated.

Issues:

  • WiFi performance stops and starts (without the WiFi disconnecting), ranging from 2MB/s to 25KB/s
  • If anyone else is using WiFi actively, the entire WiFi network goes down, WiFi speeds drop to 0KB/s for everyone but wired internet connectivity stays unchanged.
    • Once I disconnect from the home WiFi network, everyone else's speeds shoot back up to normal

Fixes Tried:

  • Reformatting my computer
  • Uninstalling driver, reinstalling manually
  • Unchecked "Allow computer to turn this device off to save power" in Device Manager
  • Wireless Adapter Power Saving set to "Maximum Performance" in all power schemes
  • Connecting to 2.4GHz/5GHz WiFi
  • Resetting Wireless Router
  • Two WLAN reports attached below, both show the network being disconnected by the driver
  • Resetting TCP/IP by netsh int/winsock reset commands

Some Info about my setup:

  • Laptop: https://www.gearbest.com/laptops/pp_654248.html Jumper EZBook 3 Plus
    • I've talked to others who have the same laptop I do, they have poor WiFi range, but nothing so severe as the entire WiFi network going down
  • Router: D-Link DIR-810L Wireless AC
  • 100MBPs down, 10 MBPs up cable internet
  • Wireless driver U-APSD Support is disabled
  • Wireless driver
