My zfold and zflip will only connect to wifi 6e (6ghz) on the router. Using wifi scanning apps, the nodes 6e network doesn't show at all and even standing next to the node, it will connect to the routers 6ghz network with a very weak signal (since it's far away behind a wall). The phones and routers are all on the latest software.
In reviewing the specifications for your router, it seems the router is designed to automatically connect you to the band most appropriate for your device. There may be a setting that needs to be adjusted in the router to allow to 2.4 and 5GHz connections. We recommend reaching out to ASUS for additional assistance.
If you are still unable to connect to the other bands, we recommend having the phone evaluated by an authorized service location. https://www.samsung.com/us/support/service/
