Router yes, actually router is running coreboot and tiano core with OpenWRT. Does still have proprietary microcode though, and WiFi firmware. All my WAPs also run OpenWRT. I don’t have a modem, I have fiber. The ONT is probably running something proprietary but as far as I’m concerned that’s ISP equipment, not mine. Phone…not quite. I tried…it is running an AOSP rom…but going to a full Linux phone never quite worked out. That being said I was originally referring to my laptop and desktop which make use of no proprietary software or drivers. I do go FOSS to the extreme as much as possible. I just haven’t figured out the phone. I did try going f-droid only for a while but it made basic tasks on my phone substantially more difficult.
