It's awesome to see these projects are still alive and kicking but they feel like a relic of a past era nowadays. Much like how stock ROMs on Android have improved to the point that rooting isn't really beneficial in most cases anymore, the stock firmware on the majority of routers is perfectly serviceable. I'm sure there are still some corner cases where they are as transformative as ever though.
I installed MerlinWRT on my Asus router and it greatly improved the smart steering between 2.4 and 5ghz. Before installing it the router would steer me back and forth very often no matter what I set it too, and I would often drop connection. After Merlin it is rock solid.
I agree. Back in the day I used to run DD-WRT on a cheap $75 router to get features you’d only get on $200+ routers, but now a days I think there’s better options. UniFi for example is great if you don’t mind spending a bit extra. Otherwise I’d rather just use PfSense.
It makes wifi! I'd say that stability and performance are probably identical. I don't especially mistrust Ubiquiti, but running open source feels nice, and it gives me nerd cred.
I have worked with a gigabit ISP for a number of years, and personally haven't seen that much improvement in stock firmware. If anything, I feel like it's more a matter of hardware improving to the point that the clunky stock firmware can run ok.
