Yesterday, I migrated my server from TrueNAS Core to a Windows mini PC running Windows 11 Pro. At the point when it detects NICs and flow control, it reported 6 NICs while there are 2 ethernet and one Wireless. I chose the correct flow control option and it did not change the settings for the 2 ethernet adapters and would not pass this point. I manually disabled flow control on the two nicks and channels did not detect the state as OK. To continue, I checked the Server Enabled box and all was good.
I'm reporting so that this can be corrected allowing novice users to install. I'm also surprised that flow control would make a difference. I suspect that somone had a bad NIC driver and/or switch that lead to problems long ago. Possibly the flow control test is no longer needed.
