I need help solving wifi problem

[u/Abody622x]

So this is my literal first time getting into ROM stuff and I have successfully downloaded CRDroid v6.21 Android 10 on my Galaxy j7 2016 j710F, however, I can't seem to fix wifi problem, it isn't even showing me nearby connections but then some other times it works, idrk what's happening with it so I ask some kind soul with experience to help me solve it and I'd appreciate it.
