Dell XPS 8940 Network Issues
My desktop is having a lot of issues with a stable internet connection. Both my Phone and my laptop can easily get ~80 Megabytes per second, while my desktop, which is right next to both devices, gets up to 10 Megabytes per second and often drops down below 1 Megabytes per second. Here's some information from my desktop
I have tired changing to basically every type of wireless mode and these settings are the same as my laptop. I know my router can run 802.11ac and n, yet Killer's drivers refuse to connect to 802.11ac even when I select it. My router doesn't have any issues as it is just this computer that is experiencing issues. I have already updated all my drivers as well as restarted both my computer and my router. Any help will be greatly appreciated!

Do you have the latest Killer WiFi driver installed?
Sometimes with Killer, you have uninstall everything using their own uninstaller. And then install the latest Killer control panel from the Microsoft store and configure it for your WiFi card, making sure it's not set to limit bandwidth to the PC's WiFi card. Follow the link on that page to the Killer Control Center FAQs for discussions about the settings etc. NOTE: Killer was just acquired by Intel so the link I posted will take you to an Intel site.
Also, you may need to change some Windows settings. Open Device Manager and double-click the entry for the Killer WiFi card. Click Advanced tab and make sure Wireless Mode is set to a/b/g/n/ac and Preferred Band is set to 5 GHz, assuming your router is dual band. And on the WiFi card's Power Management tab in Device Manager, make sure the box "Allow PC to turn off..." is NOT checked.
Next open the Win 10 Power & Sleep screen. Click Additional Power Settings. On next screen identify the active Power plan and click Change Plan Settings. On next screen, click Change Advanced Power Settings.
On that last screen, set Wireless Adapter Settings to Max Performance and set PCI Express Link State Management to disabled. Save the changes to the Power plan and reboot.
See if that helps...
