About 6 months in the pandemic, I replaced a Securifi Almond+ with an ASUS RT-AC68U running
Asuswrt-Merlin firmware; it's been rock solid and provides a good balance in features. Prior to the Almond+, I had been through a series of LinkSys WRT-54Gs and a TP-Link, all running various open-source firmware replacements dating back to the early 2000s.
