My phone hasn’t been able to connect to my WiFi and I haven’t had more than two bars for signal service. My daughter’s phone is experiencing the same issues as well. We both have the 8 plus.
iPhone 8 Plus, iOS 13
Hi, you can check this resource: If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network
Are you able to connect to other Wi-Fi networks aside your own? How about mobile data, does it work?
You may need to contact your mobile carrier as to why you're only getting 2 bars for signal service.
Download the latest iOS update on your phone, go to Settings > General > Software Update.
If the issue persists, you may need to restore your phone as new:
