lamp (npub1d8y…g8p7) Hmm… If everything works right after bringing the interface up and breaks after some time, my guess would be the router announcement (either addresses or route) expires. You can check that by checking configured addresses (they would be in the deprecated state) and routes (default route would disappear).
Now, why would that happen? Content of RA is valid only for certain amount of time. Upon bringing the interface up, client sends router solicitation message and gets RA in response, possibly over unicast. Afterwards the router periodically multicasts RAs, which resets the expiration timer.
My guess (you'd need to verify it) would be those periodic RAs are not reaching your Windows. Either because they're not send (router issue), dropped in transit (some switch/access point having a problem with multicasts? Some firewall?) or not received by the client (Wi-Fi power saving? Wi-Fi driver issue? Local firewall?)
That's of course guessing :-) Sniffer is your friend.
