If the wireless link is fine and it still hiccups every few minutes you might be hitting DPC latency spikes from drivers. I ran LatencyMon and it pointed at my Wi Fi driver and the Nvidia audio bus. Updating one and rolling the other back stopped the stutter. As a quick test toggle airplane mode and play music for a bit if it smooths out then the network stack is likely the culprit. You can also try turning off spatial sound and audio enhancements and unchecking exclusive mode in the device properties. No more hiccups.
