I don't think any change is made on hardware side when teaming 2 adapters.
You can try to remove/reinstall NIC drivers from device manager. There should be a virtual adapter when you create the team. You may also try to post the question in the
Wired Ethernet forum.
There are no devices in the device manager anymore - not a virtual adapter nor are the 'real' adapters shown anywhere - if I add them manually they will not appear in control panel so no option to reach the software from there.
I reflashed the BMC and BIOS and this did not have any impact.
Will post the question in the wired ethernet forum as well, but answers still welcome!
