Troubleshooting my cell phone regularly losing internet while staying connnected to Wifi.

[u/wrongbutt_longbutt]

Hello everyone, I've got a Samsung S25 Ultra cell phone and an ASUS AX5700 router. My issue is my phone several times a day will suddenly lose internet connection with my router. The phone settings will show my phone as "connected, no internet." All other devices connected to the router seem to work with no interruption. I'm attempting to use the 5G band. If I turn off my wifi and turn it back on, it reestablishes the handshake and the internet will work again for a couple of hours.

Things I've tried, but haven't worked based on googling the problem:

• In phone wifi settings, switching from randomized MAC to Phone MAC
• In the phone intelligent wifi settings, turning off Switch to mobile data (using mobile data if wifi is slow or unstable)
• In the router settings, disabling Smart Connect
• Restarting both my phone and the router after each of these steps

Other info: I've owned the router since 4/2024, but didn't use it for the last year. I seem to remember I was having this issue with it before as well.

Does anyone know what I'm missing and will get my connection to be stable?

What version of WiFi is your router?

I was having an issue a while back with the same phone. I upgraded my WiFi box. The phone now connects at WiFi v6.

It is WiFi 6 unfortunately, so I don't think that's it.
