But, but, but.... some of their stuff ran OpenWRT! Or still does? Don't know exactly, other stuff runs that also, for less money, sometimes faster. less hot, and less ugly cases.

OTOH I still have a https://openwrt.org/toh/tp-link/tl-wdr3600_v1 running somewhere 24/7 since I don't even know exactly anymore. As 'managed' 5-port switch, the feeble WIFI only passively gathering information.
