Same here, had WiFi issues for a while. Tried a few apps before finding the one that actually works well. Simply put, check out NetSpot for iOS. It’s a fantastic app for analyzing and troubleshooting your WiFi network. The interface is user-friendly, and it gives you comprehensive info on signal strength, potential interference, and dead spots around your house. It’s helped me pinpoint the weak spots and optimize my WiFi setup.
