Sometime when reboot/reflash router, I see serial console messages: [ 5.868712] init: - preinit -

================= FAILSAFE MODE active ================
I noticed when wifi on/off switch on router is on, sometime it accident enter failsafe mode. If switch to off, it's not happen.
Issue happens with 841n v8/v9/v10 & 841hp v3 (same hardware as v9/10) model.
The text was updated successfully, but these errors were encountered:
So, this tells us that the router thinks the rfkill button was pressed. With the 841n v8, it appears that rfkill is actually a switch, so having it "enabled" would permanently send "button pressed" ...
However, this only applies to the 841n v8. For 841n v9/v10, the button is actually a button and the problem should not occur.
