@Lacleber Hello, what is the name of the world game, please? Except for the Archer C6 router, are there any other changes in the network, such as ISP or modem? If no other network changes, please...

@alfische Is the country code of your AX20 an EU version? And the hardware version is V1.0? There is already a newer version on the official website: Archer AX20(EU)_V1_210902

@A.Rehman1124 Hello, as replied to Slyguns, only Archer C50 supports Facebook Wi-Fi. You can follow the below guide to configure it: https://www.tp-link.com/support/faq/2298/

@Yal I'm wondering have you ever upgraded the router firmware? Was there anything abnormal?

@uzulo May I know the current firmware version of the Archer C60 now? When did you update it? Is the country code an EU or US?

@Empire80 No matter you do port forwarding for that reserved IP address or not, it must be in the IP Address Pool if you configure the Address Reservation for it.
