how to turn off the dhcp server on the Cisco DPC3825 DOCSIS 3.0 Gateway
I think you may be asking how your Cisco DPC3825 modem can be bridged (this would disable the router features for your modem and would allow you to use your own router instead)? If that's not what you're asking and you require a static IP address, a Shaw Business account would be needed for this. If you can clarify a bit more what you're trying to accomplish here I can provide more information.
in the Connection Mode on the router it can be on DHCP or static I need it to be on static
On the router? Your own router?
Then yes, you will want to have your DPC3825 modem bridged, but without a business account, you will have to use DHCP - no Shaw static IPs on residental accounts
If you just want to disable the DHCP server but not bridge the modem, Setup > LAN Settings
Enable/Disable should be there
Edit: Wait is the that DPC3825 router? Not your own? That setting has no effect or bearing on the DHCP server. That is if Shaw is giving your router a static or DHCP IP, and again, unless you have a business account, you need DHCP. If you do have a business account, you can set that to static, enter your IP, and the DHCP server in the modem/router can be left enabled, unless you want it disabled
