Hi all!
I have a TP-Link TL-MR3040v2 device. Something happened with this router, because if i want to turn off, the power led remain on, but the device shuts off. The led turn off only when i remove the battery from the router. All other functions works well.
I found an old topic for reserve engineering but i didnt find an answer there. (and also the picure links doesnt exists, because the topic is very old)
Any tips?
I dont want to throw out because of this.
Thank you!
You should throw it out for security reasons alone, as it can't run a supported version of OpenWrt for already half a decade anymore.
yes, i know this, but i use this far away from civilization(no internet connection, no other peoples in the area), only in local network to control matchines remotly by phone.
Its very comfortable to use this type, because it has an own battery, no external power supply needed.
So any tips? 
The pcb diagrams can eadily be located from fcc id printed on label.
