I just very awkwardly upgraded firmware versions. I must have clicked on the Upgrade SNAPSHOT url instead of the plain Upgrade. Should I reinstall the regular 19.07.06? It's working so far FWIW.
LuCI tells me I have:
Firmware Version OpenWrt SNAPSHOT r15624-2d72be766d / LuCI Master git-21.020.56896-af422b1
BusyBox v1.31.1 () built-in shell (ash)
OpenWrt SNAPSHOT, r15624-2d72be766d
Did I install some weird pre-release snapshot? This is my hardware:
TP-Link Archer C7 AC1750 v5
