Did you try Cloudflare Free DNS? 22.214.171.124 and 126.96.36.199?Found the problem. Auto dns were 188.8.131.52(google) as primary and 184.108.40.206(act) as secondary
changed to act one as primary and secondary as 220.127.116.11
18.104.22.168 is getting spiked latency for every alternate ping. while 22.214.171.124 is better is lower range.
ACT dns is lowest out of three.
working better now. feeling 100mbps even while surfing.
