After owning this router for over a year, my family started complaining that their phones would receive the following message when connected to the router: 'Connected, without Internet.' To troubleshoot this issue, my son generated random MAC addresses until he was able to connect with Internet access. However, this solution only worked for a day or two before the problem returned. I rebooted the router, but it didn't resolve the issue. I also performed a firmware reset and set up the router from scratch, which temporarily fixed the problem. However, I'm unsure what else to do besides informing TP-Link about this issue. I want to ensure that not all wifi devices experience this problem. Additionally, I have Nest and Google devices that connect without issues, except for one Google Home device, which I had to reset for it to work after setting up the router from scratch.

Can anyone help me resolve this issue?
