and I also would like to learn how to setup my 10 mbps bandwidth by using ether2

You cannot do 10+4=14 unless your service provider allows you to bond them together. This has to be provisioned on the ISP side.

You can, however, do load balancing between them so some of the traffic goes on ISP connection #1 and other traffic on ISP #2, but you can not “add” them together for faster speed unless it is also done on the ISP side.

So short answer, no. Long answer, maybe… ask your ISP provider.

PCC is going to be your best bet.
