Latency jumps around, causing constant annoying jitter

I sampled a couple WinMTR traces. Can anyone assist with where along the way the issue(s) lie(s)?

Last week:


Today:

You appear to have packet loss starting right at your router. Do a full power cycle of router/modem, then run WinMTR again.

I actually did cycle the router just before these.

It seems to be worse at primetime (both these traceroutes are at primetime).

Are you sure the issue is at my router? The initial loss listed is 1% but it rounds up. It's only 4 packets out of 1531 = 0.26%. There's no way that can be causing the insane jitter I'm getting, surely?

For comparison, here's a traceroute outside of primetime, with more lost packets at my router. Yet it's a night and day difference, no jitter.
