I often ping my nodes, do speedtest, and use pqtest/leechtest to see real internet performance.

I got sometime such packet loss (that is how we call this) if:

1-) There are weak links between nodes and/or gateway. Especially links weaker than 96/97 looses packets. Packet looses increases if there many nodes close each other in the vicinity with weak links.

2- If you ping the node more than 1 hop away ie 2 or more hops, you might have good link in the first hop then you may have weak link afterward so again you loose packets on the way.

3- Signals might not be equal on the both side. for example, if you check node A from B and you see link with good strength such as 98 but when you look at node B from A you see 95. In this case, node A cannot hear node B well or node B sends signal lower. Try to increase the power level of node B slightly.

4- There would be many other reason for packet losses: Moons's place, sun, wind, rain, heavy traffic, someone lauhged loudly near antenna etc :) You may never know exactly what the reason is.

Once I see one of my nodes loosing packets over 30 % which is terrible. Then we found out that rain leaked in the connector.

Make sure you have a solid link, preferably over 100 in a place where there are more than two nodes around. SNR is a good indicator, see at least 10 dB difference in sigspy to minimize packet losses.

You may still loose packets even if everything is OK due to the collison on the air like in an ethernet. But this is negligible.
