DSD 128 from NAS stuttering

I wouldn't say nothing is wrong, those ping response times are huge.

I get these from my device connected via Ethernet:

Code:

64 bytes from 192.168.0.26: icmp_seq=1 ttl=64 time=0.255 ms
64 bytes from 192.168.0.26: icmp_seq=2 ttl=64 time=0.214 ms
64 bytes from 192.168.0.26: icmp_seq=3 ttl=64 time=0.242 ms
64 bytes from 192.168.0.26: icmp_seq=4 ttl=64 time=0.228 ms
64 bytes from 192.168.0.26: icmp_seq=5 ttl=64 time=0.248 ms

And from a quite low quality WiFi connection:

Code:

64 bytes from 192.168.0.26: icmp_seq=1 ttl=64 time=1.26 ms
64 bytes from 192.168.0.26: icmp_seq=2 ttl=64 time=1.52 ms
64 bytes from 192.168.0.26: icmp_seq=3 ttl=64 time=1.95 ms
64 bytes from 192.168.0.26: icmp_seq=4 ttl=64 time=1.22 ms
64 bytes from 192.168.0.26: icmp_seq=5 ttl=64 time=1.20 ms
64 bytes from 192.168.0.26: icmp_seq=6 ttl=64 time=1.64 ms

I connect all of my devices(Nas, pi, pc and chromecast) to a netgear r7000 router. I tried to ping my nas from my pc while not playing dsd128. It gives me <1ms. After i started the music, it gives me much higher pings (around 25ms). Coping a large file from nas to pc will not cause high latency. It looks like the dsd file transfer is causing the huge latency to the whole network. Do you think purchase an unmanaged switch could be a solution for this? Thank you!
