Subject: Re: [Starlink] Packet losses in a router
Date: Fri, 4 Nov 2022 13:54:26 +0100	[thread overview]
Message-ID: <CAC=tZ0q8HYHFDAV-h3gQxiR-5J-v4iR9M0Cvk=LmVJXL7YD1sA@mail.gmail.com> (raw)

FYI: The issue with packet losses was solved after the router was
properly synchronized using NTP, reaching up to 100 pps during 60 s
without losses and latency < 20 ms.
