Greetings hive mind, Mysteriously my router broadcasts both it's 5G networks at exuberant strength of signal, but the 2.4Ghz network is at 90dbms from a mere 30ft away. When I place my phone directly beside it, it can then detect and join the 2.4ghz network but get no internet through it. If pertinent, I'm trying to use an older smart tv that needs a 2.4Ghz wireless, which I've confirmed works with another 2.4 GHz network at another residence. -Router firmware is up to date -used wifi analyzer to choose less utilized channel -I have restarted, and factory reset the router.

     Equipment:
     -Verzon Fios ONT
     -TP Link 5400 V1 wireless router

Please and thank you for any help!

Edit: ONT, not modem
