The reality is that Wi-Fi routers can do their jobs without any real maintenance for years. However, if you've purchased a flagship-level phone or tablet after 2024, your device will almost certainly support Wi-Fi 7. You may see Wi-Fi 6, 6E, and 7 networks more often in public settings like retail or other businesses. If your Android phone isn't displaying a number on your Wi-Fi icon, that just means you're on a Wi-Fi standard that isn't the very latest. Even if both devices support newer Wi-Fi standards, connections can fall back to previous standards if interference or a fault occurs.
