Yes.

My combo cable modem/Wifi router is secured with WPA2/PSK, and the firewall is enabled. I also have remote administration turned off, since I have no need to do so. If I need to make adjustments on my router, it happens from my desktop, which doesn't have Wifi and connects via a CAT5 cable. If I connect to do admin, I must supply the admin password.

For my ISP to be able to see what connects to my router, I'd have to turn off security, enable remote admin, and let them in. I have no reason to do so. The past couple of times I had issues with the modem I needed to talk to my ISP about, the first case was my original modem finally failing and needing replacement. The second was a needed firmware upgrade. But all the tech could see from his end was the modem itself and its status. He could not see what was behind it, and had no need to. He could talk me through what was needed.

Before I got the new combo modem/router, the cable modem connected to an external router. My router of choice was a Linksys WRT54G. That model used a Linux kernel, and because it did, the firmware was open source and could be modified. Various folks did, and my third party firmware of choice was a product called Tomato. Tomato had a vastly improved HTML interface to router functions with a finer degree of control, and would let me SSH into the router to get to a command line. My SO was bemused that I could run vi on the router to diddle config files.

The Linksys finally failed, and the later WRT54G models dropped the amount of installed memory and switched to a different OS kernel that was unhackable. To get a Linksys with Linux firmware, I'd have to get the WRT54GL model, at a higher price.

I've been thinking about getting an older Linux WRT54G off of eBay and running Tomato again. I'd put the TWC supplied Arris modem/router into bridge mode and let the WRT54G handle DHCP and routing. It's not a pressing issue because the Arris is configurable enough. It's mostly because I like to play.
