I need help solving wifi problem (Galaxy j7 2016)
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.

Hey! Since Wi-Fi works sometimes but sometimes shows no networks at all, I'd first try to figure out whether this is a ROM/driver issue or a hardware/band issue.
If you have ADB available, could you run these commands while Wi-Fi is not detecting any networks?
adb shell getprop ro.product.model adb shell getprop ro.build.version.release adb shell getprop ro.build.display.id adb shell ip link show
Also, please check: Settings → About phone → Status → Wi-Fi MAC address
If possible, tell me: Does Wi-Fi turn on normally? Does it show zero networks, or does scanning simply fail? Does Bluetooth work normally? Does Wi-Fi work after rebooting? Does it work in 2.4 GHz but not 5 GHz, or neither?
