Windows 10: High DPC latency (especially ndis.sys and tpip.sys)

I've had a problem with DPC latency for several months (craks/pops/random dropouts when listening to music/sound). I recently found out about LatencyMon and let it run for about 15 minutes. The result is pasted below. I'd appreciate if you could suggest what to do next.
Am I correct in understanding that the latency caused by ndis.sys and tpip.sys happens because I'm using a WiFi network?

Thanks in advance for your help.

LatencyMon result:






CONCLUSION
____________________________________________________________________________________________________ _____
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:15:17 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
____________________________________________________________________________________________________ _____
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 75946.154715
Average measured interrupt to process latency (µs): 8.786541

Highest measured interrupt to DPC latency (µs): 74260.822879
Average measured interrupt to DPC latency (µs): 4.782860

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

after windows update, audio lagged/crackling, high latency

That's not on my services. I'm still struggling with this issue. I've narrowed it down to my wireless adapter driver ndis.sys is causing serious DPC latency.

 

Very high DPC latency on Win10 in ndis.sys

there was a post with the same problem:

ndis.sys- High DPC latenecy / High DPC CPU usage

which was fixed by disabling power management for the network adapter.

 

Hi, I note your Windows build is older- 15063. There was at one point an update said to resolve a problem like this some were experiencing- I can't find or recall which it was, but a year or so ago perhaps. Are you up to date with current updates for your build?

You may like to search this forum for 'crackle' - you will find a number of threads.

I have had this same issue for ages, no help about other than the usual - update everything. It doesn't work. There is definitely a conflict somewhere between the sound driver and network drivers NDIS and TCIP. Who knows how to fix it, i dont know. I have looked for ages.

 

Seems a number of reports for Acers.. anything on Acer's forum?
These just for illustration- there'll be a lot of reports and no solution, I'd guess..

Try using an older version of your network driver. (Can you roll it back in Device Manager?)
If that works you will need to protect it from being replaced by a driver update.
