Hi,

I have a Linksys WRT1900AC v1 running DD-WRT v3.0-r47581 std (10/20/21). I also have a Samsung S20+ phone running Android 12.

I can happily connect my phone to my access point using WiFi, and use it to browse the web normally.

When I leave my home, the phone automatically switches from WiFi to 4G cellular data, and this works fine.

However, when I return to my home and automatically reconnect to WiFi, my phone says "connected without internet" and I cannot access internet traffic. I can fix this by reconnecting to WiFi, but this is inconvenient.


This only seems to affect my 2.4GHz access point. On the 5GHz access point, my phone reconnects to the internet as expected.

My 2.4GHz access point is in AP mode with Mixed wireless network. WPA2 personal security is enabled. All other wireless settings are on defaults, except the SSID and I have selected wireless channel 8 as it is free.

Any idea how to troubleshoot this? TIA

r47720 fixed wifi cutouts for Marvell series, but at this point upgrade to a build from this year so try r48432.
