Huawei B315 Router | does not want to turn on after resetting, it turns on for a minute and then goes off, while during this minute it is not visible to devices when connected to the power supply, only the power icon lights up.
Did you do any update on this router or it just happened overnight? Have you tried to reset the device with the button? It looks like the router firmware is not loading properly.
I did not update practically, it happened overnight and I have no idea what to do next and I am completely green in this topic, do I need to upload any updates, if so, how?
If it does not respond to reset (button on the housing), unfortunately, without the USB / RS interface and the appropriate knowledge, you will not do anything. The router firmware is corrupted.
