Based on my experience only: Traceroute works, but only if there is SOLID communication over all hops in the path. I can traceroute through known good paths, but anything marginal and it fails.

Yep. Only when direct line of sight have I been successful. And sometimes it still fails for some reason. Like in the same room. Might be the heltecs or something.
Like I can see the signal going out via RTLSDR but then nothing sometimes comes back. Not sure why.
Only when direct line of sight have I been successful.
I've logged a couple of traceroutes that crossed state lines:

Skiðblaðnir (CLIENT_BASE) and Ἀργώ (CLIENT_MUTE) are collocated so positive SNR is expected. Likewise the positive SNRs within the greater Muskegon area are explicable. Technically, though, Sheboygan, Muskegon, and Milwaukee are each over the horizon from one another so any signal at all (even with greatly negative SNR) is remarkable. Getting a round-trip twice within 24 hours is outstanding. I believe (and I am unanimous in this) that the high temperature gradient over the cool waters of Lake Michigan causes refraction of the radio waves. Thus, the apparent horizon is much farther out than supposed.
Of course, these conditions are exceptional and successful traceroutes even under such conditions are rare.
Thats awesome! We have done 7 hops to get to the bay area from central CA. But like you said its VERY rare to get it successful. Ive seen meshcore do better, but its more setup for that sort of thing.
The issue is consistency. Since these devices run at max 1W, a "loud" device like an AC, refrigerator, or some lights can cause issues with the LoRa spectrum. Even sometimes in the same room, I see meshtastic stop working 1/10 times. and it goes to 9/10 if its over 500 ft with trees and such in the way. Just some observations.
Ok, that seems to track then. When I do get my single 2-hop return it's through a link with SNR under -10, so that is probably just not stable enough for the traceroute. Frustrating for sure.
Guess i'll spend another couple hundred on some additional hardware and start coating the hillsides with them lmao
I had similar issues with Meshtastic's traceroute. Have you tried Meshcore? The design is a bit different in that it keeps the client nodes and repeaters separate, and repeaters are meant to be kept in more stable positions. I bring it up because in Meshcore you can manually select specific pathways to probe and analyze hops in greater detail. If there is an active Meshcore network in your area you might want to give it a try. It runs on the same hardware, so you can flip between systems, but the meshes cannot interact.
Meshcore is partially proprietary which makes no longer an option for me personally
Oh, is it? I didn't know. What part is?
The mobile apps I believe
Meshcore-open fixes this. I am an open source maximalist and would not touch meshcore until there was a mobile app that was not proprietary.
The Lora radio in these devices is not open source.
I've considered Meshcore. There is no Meshcore infrastructure in my area though, and Meshcore is also not ideal for my use case (which is going to involve a lot of mobile GPS tracker use in forest areas without infrastructure nodes, somewhere meshtastic shines a lot brighter).
I'm mostly just peeved that Meshtastic's built in tools don't work very well lol.
Meshcore does now have client repeat mode which lets companions repeat like they do in meshtastic, but it does stick you on to a different frequency so that you don't mess with the regular mesh.
Have a look at client repeat mode. May be worth a try. https://blog.meshcore.io/2026/02/13/off-grid-client-repeat-mode
Traceroute uses ICMP echo requests ("pings"), and a lot of public routers have been blocking them since like 7-8 years.
I'm talking about Meshtastic, decentralized P2P messaging using LoRa radio devices. Not the internet.
Lost Lemming moment
this was my though. people are talking about the quality of the networks and stuff and im thinking. I thought places blocked it so you generally would see you local stuff and then stars and once in awhile backbone things that sorta can't block it because they are to important.
