I know this is a fairly common issue when searching here, and elsewhere online, but basically every post ends without a resolution to my issue, so here goes.
I have a Nest Wifi Pro, connected directly to my gigabit fiber modem, and wifi speeds are close to gigabit according to the built-in speed tester.
HOWEVER, when connecting to my Netgear GS108 switch, the link is negotiated to 100Mb, and not gigabit, indicated by only the left ethernet port light coming on, and not the right one. This is confirmed by using ports on the switch, including ones which DO show gigabit connection, indicated by both lights coming on.
This leads to all hardwired connections being limited to 100Mb, and not the 980Mb that the Nest Wifi Pro is showing. This tells me the Nest Wifi Pro is indeed getting gigabit from the modem, and that tracks with Wifi giving much higher speeds than wired. Wifi works alright, but some devices must be hardwired, and it's preferable for stability overall.
All cables between all devices are CAT6. No CAT5 anywhere, no CAT5e anywhere. This isn't an IPv6 issue, or a DNS issue, or a bridge mode issue. I have toggled Nest Wifi cloud services off and on. And yes I have restarted all hardware, unplugged, waited several minutes, and tried again, all with no change from the 100Mb negotiation.
I'm being very specific and verbose because, without fail, every single one of these posts has some "community specialist" come in with the same copy+paste solution, so I don't want to waste time going over steps that have already been completed or are not relevant to the issue at all.
Is this just a hardware issue with the device? A firmware (on 3.76.47819) issue? Any advice beyond what I've already tried would be appreciated.
