After switching to ER707-M2 I'm experiencing strange situation during downloading huge (~30GB) updates for games, but only on Xbox Series X. Download using PS5, PC/MAC is not generating this problems. During download process PPPoE connection is terminated and from statistics I see that the same time processor utilisation increase from 3% to 41 %. Situation happened on different firmware versions.

I checked logs from router and I see following information:
