I need assistance to downgrade my TP-Link Archer C80. After updating to the latest firmware version (1.13.15 Build 240812), I’ve noticed that the Wi-Fi performance has significantly deteriorated. This issue is particularly evident when using a mesh network setup with the RE305 extender, as the network frequently disconnects after the update. Could you please provide guidance on how to revert to the previous firmware version? Your support would be greatly appreciated.
