Check out the OpenWRT Table of Hardware, it has a list of firmware mod-able off the shelf WiFi routers that work with, you guessed it, OpenWRT. It's rather versatile as it's Linux based and can handle VLANs, multiple SSIDs, and of course, you can change the DNS servers.

Mikrotik. The depth and breadth of a tiny Hex S is mind blowing.

What I did is I bought a cheap small PC with an Intel chip (i5), some RAM and an SSD. You can find these with more than one NIC pretty easily from Amazon, and they are just normal computers: only small and quiet. Then go with a virtualization platform such as Proxmox, and to that, install opnSense as the router distribution and use the rest of the processing power to run everything else in your house in virtual machines: Home Assistant, media server, you name it... Just search Amazon with something like "router pc" and you get a long list of machines below and over 200 euros that are more than enough for your home. Computers like this one.

The great thing about opnSense is how it gets regular updates. And when you use a normal PC as your router, you run the latest FreeBSD kernel and get updates basically as long as opnSense is developed.

You probably also want a Wi-Fi. These boxes usually miss it, and even when they have a Wi-Fi card, opnSense is not really great for setting wireless networks. I just bought a few APs from Ubiquiti. They are a bit on the expensive side, but I just don't need to touch these things after setting them up and the network never fails on me. There are also much cheaper APs in the market, just get anything that fits to your budget and plug it to the router.

Pfsense is fantastic. Extremely flexible. I am contemplating switching to opensense when it's time for an upgrade (it's been running seamlessly for many years, but someday I'll need to).

Note that it's a router, not a wireless access point. For that I use a few Ubiquity APs (I forget the model).

Surprised to see no mention of the Edgerouter X in this thread so far.

Honestly, if you're looking for a simple, highly customizable router that comes with its own hardware, and don't mind supplying a separate access point, you really can do a lot worse than the ERX. They're small, highly affordable, use very little power, and it's all just Debian under the hood so you can do an astonishing amount with them.

Opnsense or openwrt devices.

If you don't want to go the route with building your own hardware there is also mikrotik with which I'm pretty happy. Something like the hex s is pretty cheap and has a sfp port if you have fiber.

I've got a Mikrotik RB4011, and I couldn't be happier with it. It definitely has a learning curve, but once I got it setup how I want, it just works. I'm sure some other options have the same feature, but one of my favorite things is a script I have run every night that emails me a backup.

I've only ever had to use it a few times, but having a recent backup of my router on hand all the time is nice.

Surprised that no one has mentioned the Fresh Tomato project

There's a ton of functionality built into it, and it is regularly updated.

Literally anything that's not ISP provided should give you the flexibility to set your own network parameters, but if you want strong flexibility beyond that, I'm going to throw my recommendation to opnSense, it's a fork of pfSense and the only reason I like it over pfSense is that the interface is very different and to me, it makes a lot more sense in how it's laid out.

That's personal preference, YMMV.

For consumer gear, ubiquiti has some strong units, the ER-X is pretty reasonable, but the unifi line is somewhat more beginner friendly, but tends to bury advanced features a little bit, focusing more on usage and reporting of activity and such.

Lower end consumer, the usual contenders are tp-link, and Netgear, though I lean more towards stuff from Asus, or anything on the dd-wrt compatibility lists... I ran a Linksys WRT54GL for a long time because of dd-wrt. I haven't kept up with the "wrt" variants over time.... The last time I touched dd-wrt was on a relatively high end (at the time) Asus router and it did very well... Might be work looking into. There's usually a trick to getting wrt firmware into a router though, and it will likely void your warranty, so buyer beware.

Circling back... My biggest issue with opnSense and pfSense, is the choice of hardware, unless you're buying direct from pfSense's netgate product line, you'll have to source something to run it on, and my biggest issue with that, personally, is that I want something small, like a router, IMO, should be, at least smaller than most PC's, that's relatively inexpensive, with at least two built in ethernet ports, since I've found that USB ethernet options are generally not very reliable. And usually, I can find something small and cheap, but there's only one ethernet port, or I can find something cheap with plenty of networking, but it's not small, or I can find something small with plenty of networking, but it's not cheap.

So I'm running a sonicwall at home, because fuck all this other junk, I just want something that does what I want it to do without hiding all my options behind some garbage, or a system that can only work a particular way, and you don't get options to change it. Or something that's huge or expensive.... Or something I have to spend a lot of time setting up, maintaining, or fixing. For me, that's sonicwall.

I run OpenWRT on a RaspberryPi and it's great. Happy to answer questions.

That's depend on how deep you want to go with router customization. Most casual enthusiasts would do fine using an Asus router. Out of the box, the firmware is based on an opensource firmware (Tomato) and has a lot of features and options compared to their competitors. Feature-wise, it already blows other consumer-grade routers out of water. And because the firmware's source is available, third-party firmware (asuswrt-merlin) is thriving and can be flashed with zero risk while adding a whole bunch of new features and customization options.

If you want something more, then your only options are using enterprise-grade routers (e.g. mikrotik, ubiquity, etc). Just note that these enterprise gears usually don't have latest WiFi tech (or even WiFi at all!), so you'll still need to buy another wifi access point and hook them downsteam of the router.

If you have a pi kicking around or a docker instance of pihole you can use it to take over dhcp of the router and then set the dns servers in pihole.

That’s what I do currently on my home hub

I use Protectli hardware with Pfsense or Opnsense. Doing this at home and in 10+ small/medium environments. Never had any issues, I highly recommend Protectli hardware + pfsense/opnsense.

Lots of good suggestions. The down side to a pc running opnsense is going to be electricity costs. If that's a concern.

Any of the Asus routers supported by Merlin will do what you need. (That's what I'm currently doing). It has a feature called DNS control that will intercept DNS lookups and send them to the servers you define.

Edit: opnsense not nonsense.

I use pfsense on my own metal. I can recommend it- never caused me any issues in the 4 years I've been using it, now. Even seamlessly updated major version twice.

MikroTik is super powerful, customizable and affordable.

Old computer, or Raspberry pi with proxmox and pfsense on it. The positive thing is that you can run other servers as well (pi-hole for example for network wide blocking ads)

Just wanna put in a good word about GL-iNet routers ... they are more travel- and pro-sumer focused than a lot of what's been mentioned here. They run a proprietary front end on top of OpenWRT, but if you don't like that, most of them have full support in vanilla OpenWRT.

These are definitely more for the tinkerer market, their documentation and firmware can have quirks, but that being said (and as somebody who wouldbe wary at that caveat) I have been using GLi routers with manufacturer firmware as a daily driver for 3+ years and once you get them set up they are very solid.

Might be a good option for the digital nomads among us who need a smaller device which can connect to a host network and then send all traffic over a VPN with very easy setup.

pfSense on a ZimaBoard 216 works astonishingly well and it's easy to setup and manage. Toss in a Mikrotik CSS610 and you have a vlan ready setup in under an hour.

If you don't like the ZimaBoard, you can go with any of the Topton style router PCs from AliExpress for a couple hundred and have a 2.5Gb router running in proxmox with docker in a separate VM.

I just bought my own hardware and loaded PFSense. Put the ISP modem in bridged mode to disable all of their nonsense.

I set the DNS servers I want in PFSense and that filters down to everything on the network.

Does the bt hub let you turn off DHCP? I had a similar issue with my ISP router, but it let me turn off dhcp and then I ran pihole which can run its own DHCP server.

Then, the DHCP server can tell all clients to use your preferred DNS server.

I haven't used adguard, but it can probably do the same. If not, you can run a DHCP client on the same box probably.

I bought a cheapish small PC with 4 Nics and ran pfsense for a long time, that's your best best. I've ended up with a Ubiquiti Dream Machine, less time to tinker and higher need for production with working from home

For me personally... I use VyOS in a VM running on a proxmox host (optiplex, SFF) with a 4-port NIC passthrough. This solves the issue of power for me, as the host has plenty of ram allowing me to run other services without needing an additional machine (although I do have one as a spare). VyOS doesn't currently have a GUI (one is in development), however, it has been very solid for me (also based on debian, which is nice).

Lot of good choices:

One of the 4 port atom pcs on Amazon, or even one of the arm ones, the key is ethernet ports and remember you'll need to handle your wifi. Put debian, pfsense, openwrt, whatever you like, it'll be great.

One of the openwrt systems, a high end glinet isn't bad, just any of the better ones.

Had a freebsd server that run a vnet jail for routing, was glorious, no notes, jut perfect.

Running a unifi dream machine se right now, mostly because I want someone else to handle security (I know it's not much, I just don't have any bandwidth for that now). Works fine, but I'm using unifi wifi so it's a tie-in there.

If you want a retail system, either openwrt or unifi, I know why people have issues with ubiquiti, but it's probably the best prosumer hardware and software you can get without using your own. I haven't used pfsense much, maybe that would change my mind.
