My under $100 router didn’t work because it had too little ram and flash storage to work. It was a few years ago though so maybe the situation has changed. I’d be interested in seeing which routers under $100 are working well with OpenWRT.

i really like my https://www.gl-inet.com/products/gl-ar750s/ : comes with a GUI on top of openWRT that allows easy static IP assignment from MAC, wireguard config as either server or client, etc. you can always drop into LuCI as well, or reflash with latest openWRT. plenty of storage for additional services and packages if that's your thing.

no affiliation, just a happy customer!
