The ISP should be supplying a default gateway address as part of its DHCP config for you. Use it.

the 68.106.112.1 is the default gateway given from my isp, by doing ipconfig all
so should i still use 192.168.1.1

Yes, the default-router command under the DHCP parameters is the default gateway the router hands out to the internal hosts. The router's ethernet interface is the default router for your internet network so use 192.168.1.1.
default-router 192.168.1.1
In your "ip route" statement on the router, use the ISP supplied gateway address 68.106.112.1.
