Need help troubleshooting

Hi! So I today decided to flash version 2024.1 on my old router (Netgear r6400). The flashing process went well and I followed all steps but I cannot for the life of me get it to connect to my phone.

Currently my setup looks like this, Bell modem connected via ethernet to Netgear r6400 and I would want to connect my phone to the Netgear r6400 via wifi. I currently have the Netgear r6400 setup via DHCP.

Maybe someone can help me due to my inexperience with these kinds of things. Any help would be amazing and I can always provide screenshots

EDIT: It is now solved after sitting for a few hours and being unplugged for that time
