To answer @plh, the new "preferred enthusiast device" is basically anything with ipq40xx or ipq806x. Those are stable, well-supported and reasonably priced.
Good examples for each:
- ipq40xx: Linksys EA8300/MR8300, AVM FRITZ!Box 4040
- ipq806x: Netgear R7800, Ubiquiti UniFi AC HD
Basically, if you are fine with around 250 Mbps SQM-enabled routing performance, go for ipq40xx. If you need more than that, go for ipq806x.
