I captured at the same time traffic on the router and indeed there are no RS from my laptop.

This is expected/conforming behavior to [[https://tools.ietf.org/html/rfc4861#section-6.3.7|RFC 4861]] - RS are only sent on a link up event, until an RA is received. RAs are sent in regular intervals by the router (so RS are not actually required, and just to allow faster router discovery). The RFC even forbids sending RS except in response to link up / interface becomes available events.

So the question is probably why windows 10 does not like the RAs. Does it ever update the router lifetime? Do you have any logs from the windows machine (be it regular output).
