I would take these projects over stock firmware on traditional home routers any day. And I have done where I’ve been unable to rig a more permanent solution. They have an honourable mission in a section of hardware filled with absolute junk.
But the trouble is the sheer number of hardware targets and meagre resources on these devices combined with the contempt of third party firmware from most manufacturers make them hard to flash and leave them rarely updated, if you’re lucky enough to have a supported device. Even then they are prone to quirks and bugs. Some devices do receive and are capable of receiving updates but they often cost more than the equivalent low TDP general purpose computer.
Just imagine: the developers of DD-WRT have to target not just each individual router model but every single revision as the manufacturers have a habit of switching major components or even entire chipsets between product revisions. On top of that the documentation for the components used might be sparse or non existent. I’m impressed that these router distributions can make it work at all but that doesn’t make it any more practical or sustainable.
At this point you may as well flip the router into modem mode and run OPNsense or PFSense and get a fully fledged operating system running on far more resources than any of these SoCs. Assuming you have the power budget you’ll get assured updates and far more flexibility with fewer compatibility issues and quirks. My passively cooled N5105 box with 8GB of ram and a 128GB HDD happily routes a 1gb/s WAN while simultaneously hosting a busy home assistant instance. The resources aren’t even maxed out.
Following my experience I will always opt to run dedicated APs. DD-WRT WiFi support is amazing considering what they have to work with, but there are only so many wifi chipsets they can support and because they try to support as much as they can there are always problems with something. I really don’t have time to constantly troubleshoot the wifi following cryptic posts from years ago. Ubiquity stuff isn’t flawless either but it’s stable and a lot less prone to hard to trace issues. YMMV.
DD-WRT and friends I love you, you really saved my ass a few times when all I had was some shitty CPE. You’re still way nicer than Cisco gear. But I find it hard to justify using a gimped out SoC from a couldn’t-care-less manufacturer when I can buy a 5W TDP passively cooled x86 computer for ~100usd.
The short answer is no, because it’s a pain in the ass and offers little tangible benefit. But I can speculate.
If I was going down this path I would look for an x86 box with a wifi card that is supported by OPNsense or PFsense(that’s usually going to be dependant on available *BSD available drivers). I don’t how well they would function but I would expect quirks. You could also check the compatibility lists of the open router distributions to find something that’s well supported. You can check the forums for posts from people with similar goals and check their mileage.
You might even be able to achieve this with an ESP32.
But what are you hoping to achieve? Do you mean open radio firmware or do you mean open drivers? Or an open OS talking to a closed radio? What’s the benefit?
Radios in any device are discrete components running their own show.
Open drivers should be possible. However I have a feeling that open firmware for wifi access points radio hardware is going to be extremely hard to find. The regulatory agencies really don’t want the larger public to have complete control because of the possibility of causing interference and breaking the rules(for good reason - imagine if your neighbour had bad signal so he ignorantly cranks up the power output, not realising that he can’t do the same with his client devices, rendering his change useless).
I seem to remember a change in FCC rules some time back that seemed to disallow manufacturers obtaining certification for devices that permitted end users to modify the firmware, much to the concern of open router users at the time. The rule was aimed at radio firmware but the concern was that the distinction would be lost and the rule applied to the entire router by overzealous manufacturers who hate third party firmware at best.
A fully open radio is basically an SDR. Can you move packets over an SDR? Hell yes, but now you’re in esoteric HAM radio territory. It’s going to be a hell of a fun project and you’re going to learn a lot, but in so far as a practical wifi ap, your results will be limited.
I use FOSS wherever it’s practical but if you want working wifi just stick to the well tested brand names. For what it’s worth you probably won’t gain any security by going open, if there’s any weakness it’ll probably be baked in at the protocol level which open devices would need to follow anyway. At least a discrete AP can be isolated and has no reason to be given internet access.
We get it, you’re the smartest man in the room. None of that was helpful for that poor soul who asked you for a recommendation on how to step away from OTS routers.
He asked for a recommendation which I can’t provide because I haven’t gone down the route he wants to know about, hence the first line and my explanation of why I chose not to do that.
I then speculated how I would do it if I were in his position. Then I broke down his question to help him examine what he really wanted: a completely free(as in open source) appliance, a free operating system and or free drivers.
Then finally I explained why you’re unlikely to get a truly free radio. I’m sorry if you or others found this unhelpful, I was just trying to condense quite a lot of information into a short post.
Opnsense and PFsense run on top of BSD underpinnings, so as long as the base OS sports the hardware you should be ok there, but:
I still don’t really recommend throwing it all on one device. At the minimum, it’s unlikely that a white-box PC with a wifi card is going to be as good for signal etc as a multi-antenna wireless device in hardware designed for such.
DD-WRT and OpenWRT can both do VLAN’s and per-interface routing, so what I’d recommend instead is having AP’s that run that software connected to port(s) or a VLAN intended for your wireless network, then having that run through your firewall (running PFsense, opnsense or whatever). You can even bind a specific SSID to a VLAN and separate your internal vs guest networks so they can’t talk to each other (or at least, not without rules on the firewall host). That also allows you to run a bit of cable and space out multiple AP’s in such a way that it provides better coverage, while still managing rules/routing/DHCP/etc so the central firewall.
I strongly suspect that those antennas are highly optimised and they lend themselves to being mounted in optimal locations. A couple of rubber duck antennas will work in the same room, but keeping that stuff up and away from all the other gear will pay dividends on the fringes of your wifi coverage.
The problem with DIY solutions is that you will be missing out on all advanced hardware features available in prosumer and industrial routers. It’s always better to just buy top of the line ASUS router than going DIY. DIY won’t give you WiFi 7 or even WiFi 6E. DIY won’t give advanced antenna array. The list goes on.
Another point for ASUS routers is that Merlin firmware is available for most of them. And new routers are added all the time. Simply because Merlin is based on official firmware from ASUS. And it adds a lot of nice features, plus gives you SSH access so you can do whatever you want.
And last, but not least, ASUS supports old routers for many years, adding new features and fixing bugs. So if you’re not comfortable with flashing custom stuff, you are still better off with ASUS product than with a competitor, as some companies tend to drop support after a measly 9 months since release (looking at you, TP-LINK).
Basically, always go with hi end ASUS - the best hardware plus really good software and support.

Any recommendations for a dedicated Wi-Fi 6+ AP that supports open firmware?

I agree entirely. Look at these lovely radiation patterns:
