I'm hoping someone can give me a good recommendation for a home router that supports DoH. I am aware of the thread listing supported models here: https://community.tp-link.com/en/home/forum/topic/617138?sortDir=ASC&page=1, although it can be confusing that the model names listed don't necessarily correspond to their retail name but instead refer to the employed chipset? Maybe I've got that wrong, but in any case I could use some help.

I'm interested in replacing my existing Archer C5400 with one that can handle DoH and IoT. My C5400 works reasonably well, although the 5GHz signal does not extend to the farthest reaches of the house, so we have to resort to 2.4GHz for some devices. I would love to get a solid 5GHz signal everywhere if that is an option. I'm guessing I may need a mesh setup for that? Also, I have no particular need for WiFi 6, in case that's relevant.

Thank you in advance for any recommendations you can make. I really appreciate it.
