i have two ethernet ports on my motherboard is it possible to syncronise them both to my router to make it faster.
If so how would i go about doing it
To go on the internet, no...
Your internet is almost always limited by the speed of your modem, not the speed of your router or ethernet port on your motherboard. If you had a gigabit router and two 10/100 ethernet ports, I guess you could get faster LAN transfer speeds over the network if you configured each port with a different mac address and IP, but I think it is worthless for what you want to do.
If you wanted to though, you could easily make your computer act as a gateway for other computers if you wanted to hook them online (in case your ISP only allows one computer on your network at once)...
