i have ping spikes on my router ASUS AX3000 V2 every 2-3 minutes spikes touch 150-250ms in Pingplotter. My connection is fiber 1000/500mb.
I tried switch off every settings, called my ISP, nothing work out to resolve problem. I turned off all devices, leave only wired notebook, factory resets...nothing changes.
Look at the picture...
Can you somebody have similar issue or you know about possible solution?
