================= 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.

Fixed for v8 in https://github.com/openwrt/op enwrt/commit/5e86877f36b0d95127dcef8ed3a bf78ecd78061d
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.
Created a PR for the 841n v8 here: https://github.com/openwrt/openwrt/pull/3184
Fixed for v8 in https://github.com/openwrt/openwrt/commit/5e86877f36b0d95127dcef8ed3abf78ecd78061d
As the v9/v10 are different, I'm closing this now.
Please resubmit for v9/v10 when you can reproduce the problem there.
