is WPA2-Personal safe to use for home wifi?

I have quantum fiber wifi and my iphone keeps saying “weak security” and I’ve called customer service multiple times and they all are really no help. I’ve changed my password and network name and I even went into a browser typed in my IP logged in with my admin info and wasn’t able to change it from there either. This all started happening when I hooked up the wifi 7 pod they had sent me. I also tried forgetting the network and everything still the same issue. My Ps5 says the security method is WPA2-Personal and i’m wondering if this is safe to use for my home internet for my whole family on all of their devices.
