Recently upgraded my MBA to Sonoma. Normally use WiFi and get around 730mbps on iperf. SMB transfer is a little erratic and around 60-70MB/s. If I need maximum network speed I tend to connect USB-C ethernet usually to second port on MBA (first port is Studio Display). iperf reports around 880MB/s and activity monitor shows solid 112MB/s. Internet Speedtest returns just over 920mbps. Finder will transfer at a solid 110MB/s as reported in activity monitor. All very unremarkable and as expected.
If I disconnect ethernet connections move over to WiFi and speeds change as expected. Finder shares stay mounted and transfer drops to wifi speed. Reconnect ethernet and system settings shows correct service order. iperf reports 100% ethernet speed as before. Finder reports wifi speeds. On checking I see that Finder is transferring over WiFi and has not moved to ethernet. Unmounting the network share and remounting then restores connection over Ethernet. Also disabling wifi restores operation and even switching wifi back on does not change things.
It appears that if a mount is established over ethernet it will move to wifi but when ethernet is re-established it does not move back yet all other services and traffic appears to do so. The change in finder is only forced when wifi is disabled (and re-enabled).
This is very strange behaviour. I do not remember seeing this on 13.X but not sure. I will check it on my mini tomorrow. Using four different ethernet adapters - Belkin as sold by Apple (bought when I saw this behaviour in case I open a case with Apple on AC+), Anker USB-C, Anker USB-3 via Anker USB-C to USB-3 hub and cheap Aukey 3 port USB-3 hub and ethernet (which matches all others on performance and surprised me). Switches are all Netgear managed and I run several VLANs. Cabling is all CAT-6 as are patch leads.
I have never seen this behaviour on other systems. Just checked it on Pi4, Windows NUC and several NUC I use with Linux as servers and things - they all work as expected and move to and from wifi/ethernet on Linux and Windows.
I was wondering if anyone else had seen this and could offer any insight? Thanks in advance for any feedback.
