what network device to use?

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

My Internet provider upgraded their "optical" equipment so I could 
support 500Mbps (and they said now it could potentially support up to 
5000Mbps) and now it appears all of my devices except one are not 
detecting it over the existing ethernet cable. No lights, no carrier.

My NetBSD 9.3 hardware is:

ppb1 at pci0 dev 28 function 2: vendor 8086 product 3a44 (rev. 0x00)
ppb1: PCI Express capability version 1 <Root Port of PCI-E Root Complex> x1 @ 2.5GT/s
pci2 at ppb1 bus 2

and

rgephy1 at re1 phy 7: RTL8211C 1000BASE-T media interface

and

(Ignore the changed mac addresses.)

That USB device above also didn't work with Ubuntu Linux with this new 
connection.

And my low-cost Gigabit Ethernet switch (which does support 1000baseT 
full-duplex otherwise) also doesn't detect it (no lights).

This new connection works with my Eero 6+ device (which doesn't 
appear to have any diagnostics to tell me what the connection is). 
(Every speed test now using the eero is maxing out around 95 Mbps down 
which is faster than I had before and up to around 80 Mbps which is also 
faster. I will research more later but I'd hope to get better than 100 
Mbps sometimes since my new plan is 500.)

How can I troubleshoot this with NetBSD?

Maybe I need a different driver, updated NetBSD system (but doesn't 
explain why didn't work on Linux either), or new hardware?

re1: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=3f80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
        capabilities=3f80<UDP4CSUM_Rx,UDP4CSUM_Tx>
        enabled=0
        ec_capabilities=3<VLAN_MTU,VLAN_HWTAGGING>
        ec_enabled=0
        address: f4:f2:6d:00:b7:57
        media: Ethernet autoselect (none)
        status: no carrier
...

Maybe there is something to enable.

By the way, with the old internet provider equipment all my devices 
would only autoselect to 100baseTX full-duplex.
