1. You would need to consult the freebsd forum for the network card. Opnsense is just a customized version of FreeBSD.
2. Realtek ethernet card is not well supported, best switch to an Intel card. But just in case it is a configuration problem, does the update server ip address resolve correctly?
3. You should be able to change your network card ip settings via console, but I suspect it is related to the ethernet card issue. Alternatively make sure you have enabled your DHCPv4 server for the card.

1.sorry,I am first time to used open source firewall and FREEBSD,so could not to consult the freebsd forum.
2.The Realtek ethernet card is made in motherboard,could not to changed,install  Ubuntu is very well,if have a function to upload file and install it, it very usefull for Chinese.It is not a configuration problem, I haven't change anything is also the same.

Another open source firewall :pfsense,ipfire are also could not find my computer ,but could not show me error in installed.

1. You would want to refer to this documentation https://wiki.freebsd.org/DeviceDrivers OpnSense is based on FreeBSD 12.1
2. Ubuntu and FreeBSD are two different platforms, FreeBSD has a much smaller userbase hence there is not as many drivers out there. A lot of things have to DIY. Intel is the most supported card.
3. You should try restarting DHCPv4 service then go under System -> Log Files -> General and see what causes the error, without logs our guess is as good as yours.
