Got any Intel i225 NICs running at 2.5 Gbps? They’re buggy and drop for seconds at a time

New driver came out today or yesterday that is supposed to hopefully fix that.
One in my desktop, but that one isn’t experiencing issues. On the network it self there is currently only off the shelf hardware without anything fancy or even 2.5G
I increasingly think this might be at least part of the problem (I think it’s more than one issue) as I definitely experienced so some DNS slowdown yesterday. I shall investigate as soon as I find some time.
Good to hear you’re onto something…
Here are some latencies of upstream nameservers at my point of presence in the past 12hrs. “Router” is my private instance of Unbound DNS (/w adverts & malicious block). All seems far below 1s (including the worst player at my POP… quad9):
I use cloudflare via DoH. But I suspect PiHole if anything.
Seems only Windows is affected anyways from what I’m reading.
