Is this a hardware issue?
Rare — most Wi-Fi issues are software or router related. Test on another device to rule out hardware.
What's the difference between 2.4 GHz and 5 GHz?
2.4 GHz has better range but slower speeds. 5 GHz is faster but shorter range. iPhone 15 supports both.
Does router brand matter?
Some older routers have compatibility issues with iPhone 15's Wi-Fi 6E. Newer models work better.
