The Wi-Fi problem has nothing to do with the battery. It is the result of a hardware failure, and the only solution is to either have it repaired or to get a new phone.
When a battery falls below 80% capacity it has either failed or is failing, and needs to be replaced. But replacing the battery will not fix the Wi-Fi problem.

You have 2 unrelated problems: your battery is failing, and ordinarily should be replaced: iPhone Battery Replacement - Official Apple Support
HOWEVER:
If Wi-Fi doesn’t turn on that’s either a broken antenna wire, or, if Bluetooth doesn’t turn on also a failed radio chip. In either case the phone would need to be repaired or replaced, and for a 5 year old iPhone model the cost of repair would not be a good investment UNLESS you have AppleCare+ or AppleCare ONE on your iPhone 13.

So what issue is causing what problems?
