I used to use an old Linksys WRT54GL v1.1 router for the purpose of testing homelab setups, but I have recently found that, as of 2022, it is unsupported by OpenWRT. So, I am now looking for a router to replace my old one. I don’t need anything fancy – I just need a router with WiFi connectivity (2.4GHz is fine, but 5GHz is, of course, appreciated, if possible), and a few LAN ports (gigabit would be nice, but it is not a necessity). By no means does it have to be a new model of router. So long as it supports a current version of OpenWRT, and satisfies my hardware requirements, it will be an acceptable recommendation
“Cheap” being relative, I think GL.iNet products are reasonably priced, and their software is OpenWRT with a customized web interface. $40 for their small, portable WiFi 5 Opal; $95 for their WiFi 6 “home” router; $130 for the WiFi 6 Opal. The Opals work fine for covering a 1br apartment, but have 2 eth ports. The bigger one (Flint?) has 4.
