This is how you do it.. I found this as I was trying to find a way to confirm that I was in bridge only mode..

So, as per OP original posting, mine does have the option to set it in bridge mode via the web interface --> under "Administration" --> "Management". Once set to Bridged Only mode, it will automatically reboot and disable all wireless functionality.

You can still go back into the modem via any of the ethernet port after via cable connection, but the default gateway is now 192.168.100.1. It is a limited web interface showing only status and a mode setting page, you can revert the Bridged only option then if you choose to.

EDIT: Also, I was able to go into bridge mode using the DPC3825's firmware. I did not have to call rogers or get super user access.
EDIT 2: You do not need to connect directly to the DPC3825 in order to access the 192.168.100.1. I can access it via the wifi on my Asus router.

I went back to using my own router as well after realizing the DPC was quite awful as a router. Anyways, didn't even need to put it into bridge mode --- I just disabled the wireless setting from within the web settings and hooked up my own router to it. I've been reading that putting it into bridge mode is the only way to use your own router with it so just saying that it's not the case.

Yes, only router with AP (Access Point) option can do that, you need to disable DHCP in the second router, so that you are not double NATing.

Thanks to OP for posting this. I found a similar thread on the rogers community

Question: is there a performance difference between
1) Cisco DPC3825 in bridge mode & connect to my own wireless router
vs.
2) Turning off wireless on the Cisco & connect to my own wireless router (with DHCP disabled on the wireless router)

Currently using method (2), and I noticed that I can no longer access the admin screen of my wireless router (ASUS RT-N53; default should be 192.168.1.1); i also had this problem with an older netgear router as well. I had to reset the wireless router, then I can access the admin screen

FWIW, I can access the admin screen for the CISCO at 192.168.100.1 (wired and through wifi)

Thanks for the post. The info on username and password was not supplied by Rogers when I picked up the unit. Saved a great deal of time trying to reach a Rogers tech. I'm using the DPC3825 in bypass mode. Easy setup once logged in.

Yes, because in config # 2 you are double NATing.
