I find the router firmware space very confusing. I’ve got a Netgear R6400 with TomatoNG. It worked well for a while but lately I seem to be having a lot of trouble with dropped connections and general sluggishness. I haven’t taken the time to try to rule out the router or anything but I did try to look up if there was any newer firmware and TomatoNG seems to be abandoned. From there I couldnt really figure out other things to try.
