I have a dell xps15 9570 laptop with a killer 1535 card(it works great without disconnecting issues). Then i bought an ax200 card and replaced 1535 with ax200. It randomly disconnected from wifi. My home network is solid (other computers and phones work great except the ax200). Sometimes it reconnected to wifi automatically, sometimes i had to manully reboot my router.
I tried everything i can think of(exchanging the ax200 card for a new one, installing newest(or old versions) Intel WiFi driver from the Intel site, installing 1650 driver from the killer site, installing 1650 driver from dell site, setting channel width, setting it to 802.11ac mode, choosing best channel, turning off power saving and packet coalescing, turning off 5 GHZ and turning on 2.4 GHz(and vice versa), exchanging the black and white antenna cables, etc) but nothing seems to change.

Thank you for submitting your question on this Intel® Community.
Performing wireless integrations is subject to country-specific legal regulations. Before installing or changing the Intel® Wireless Adapter, you must contact the system manufacturer to obtain approval, step-by-step instructions, and support. It is worth mentioning that the integration may or may not work due to the following reasons:
1. Hardware/software compatibility issues or dependencies.
2. Manufacturer limitations.
3. Driver limitations.
In this scenario, we would like to jump in and provide the following recommendations:
1. Perform a Clean Installation of Wireless Drivers (Bluetooth and Wi-Fi).
Step 1: Get the latest system-specific driver for your computer.
Wi-Fi Driver 21.70.0
Intel® Wireless Bluetooth 21.70.0
Step 2: Uninstall your Wi-Fi driver.
Windows* may have an inbox Wi-Fi driver for your wireless adapter. You can't uninstall an inbox driver (you won't see the "Delete the driver software for this device" option). Proceed to the next step if you start seeing the same version of the driver installed automatically after it’s uninstalled.
- Go to Device Manager.
- Expand the Network Adapters category.
- Right-click your Intel Wireless Adapter/Bluetooth and choose to uninstall it.
- Make sure to select the option to Delete the driver software for this device.
- Restart your computer.
Step 3: Driver installation.
Locate the driver you downloaded back in Step 1. Run as administrator, and follow the wizard to completion.
