Archer C6 v4 - resets itself to default
https://community.tp-link.com/en/home/forum/topic/716222
Exactly as the linked, every several days (15-18) the device resets itself, after 8-10 months of correct operation.
Tried also to update to firmware "Archer C6(EU)_V4_1.13.7 Build 240515_EE_LV_LT" obtaining the same results. 1 self reset with "Archer C6(EU)_V4_1.13.6 Build 240430", 2 with "Archer C6(EU)_V4_1.13.7 Build 240515_EE_LV_LT"
Mac address of the involved router is 50:91:E3:BB:6C:CF; if TP-Link ID would report on the website the registered products serial number, I would report it here.
Following the answer.
1. Ensure that the router is connected to a stable power source. A fluctuating or unreliable power supply can cause the router to reset.
Device is connected at the very same socket
2. Make sure the original power adapter is used, try another power socket/outlet.
Same exact original power adapter used since its first operation
3. Check for firmware updates and ensure it is using the latest firmware.
Had the latest "italian" firmware at the first occurrence, the latest available firmware for the hardware at the subsequent two
4. Perform a manual reset by holding reset button until power LED flashing.
Glad to perform the full manual reset when an advisory about "configuration problem for Firmware 1.13.6 will be released frop TP-Link.
Configuration has been the same since the first operation and was the same for every day of use. Configuration has been restored from a backup every self-reset.
5. Inspect the router for any physical damage or loose connections. Ensure that all cables are securely connected to their respective ports.
No loose connection or physical damage for all the visual inspections.
