ASUS ROG GA401IU Wifi has bouts of extremely high ping

I recently bought an ASUS GA401IU from their RoG line. Most of the time, wifi works well, but occasionally my connection will cut out. Pinging my router during this time results in several-second ping latency, but no missing packets. Turning off and on the wifi seems to fix it.

Seems like other people have issues with power saving. I have a udev rule that runs `iw dev <dev> set power_save off` and can confirm that that's working, but the issue still happens. I don't see anything relevant in the dmesg logs around when it happens.

My home network I'm connected to is a 5.2GHz one and uses WPA2.

lspci reports this for my wifi card:

02:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
	Subsystem: Intel Corporation Wi-Fi 6 AX200NGW
	Flags: bus master, fast devsel, latency 0, IRQ 79, IOMMU group 9
	Memory at fc800000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [c8] Power Management version 3
	Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [40] Express Endpoint, MSI 00
	Capabilities: [80] MSI-X: Enable+ Count=16 Masked-
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [14c] Latency Tolerance Reporting
	Capabilities: [154] L1 PM Substates
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

Anyone have a solution to this? Or other debugging steps I should take?
