Simple Wall-Mount Power Switch for rPi – pt2

OpenWRT on RTL8196E in WiFi repeater – pt1

Part 1 : Talk to me… So, I’ve been fiddling with this old device from 2013ish. it’s a WiFi repeater from an unknown brand. On the bright side, I managed to crack it open and find out the potential UART port (without pins obviously), and the chip inside seems to be a genuine Realtek RTL8196E, […]
