+1 for OpenWRT

You can't even trust the biggest tech companies to reliably ship software updates anymore and they've got more money than god, and the entire industry seems intent on reducing headcount as deeply as possible, killing products and projects however they see fit, ending support in the most abrasive manners possible.

I came here thinking the topic was on AI model routing, but it isnt.

OpenWRT project maintains a list of 'supported' hardware you can choose from. You can also check the OpenWRT forumns for what people are recommending and why.

If you want an OTS router then OpenWRT, but make sure it’s compatible first.

If you want a bit more power or firewall capability a minipc running OPNSense also works.
