the problem is to find what node thats unstable, but ping flooding each node will show you, but its alot of work compared to Neotrace.

this node ping suppose to be around 5-15 ms
I dont think the problem is at your equipment but, you can try pinging with pc directly connected to the modem. if its not too much work for you, keep on ping flooding your route all the way to testmy.net and see what nodes thats unstable,
