Question Periodic ping spike on 5GHz only (that gets temporarily solved by running inSSIDer)

Hello everyone. I've got something to share with you.

I noticed very long time ago, that when I connect wirelessly via 5GHz to my router, then I get periodic 100% reproducible ping spikes all the time. I checked many similar threads on the internet, none of proposed solutions helped. At this point I simply assumed that router is just too far to get reliable 5GHz connection, because it always works fine on 2.4GHz and when I'm really really close to the router, then 5GHz works as well. So I simply stick to the 2.4GHz.

But, yesterday, I noticed, that when I run inSSIDer just for a few seconds, till it loads all networks near me and then close it, the random spike is gone for few hours. It works like a charm every time. I noticed that launching inSSIDer seems to reset the driver settings in device manager, so it might be related to driver reload that probably happens during launch. I don't know.

Here is ping snippet with situation before running inSSIDer, then some general errors during inSSIDer launch and then everything works like a charm (bandwidth is also very stable ~250Mbps at this point, while before inSSIDer launch, the spikes will dramatically reduce average bandwidth over time):

Have you guys ever seen thing like that before? Got any ideas what could cause the spikes in this case and why it is solved by just running inSSIDer?

My setup:
OS: Win10 Pro 2004
Router: Archer C6 v2.0 , fw 1.3.6 Build 20200902 rel.65591(4555)
Wifi dongle: ASUS USB-AC56 via USB3.0

Thanks,
Chris
