Your router, modem, or even the Wi-Fi adapter in your device can malfunction. Aging equipment, manufacturing defects, or power surges can cause intermittent connectivity or complete failures.
ISP-Related Problems
Sometimes the problem isn’t on your end at all. If your Internet Service Provider (ISP) is experiencing outages or network congestion, it can appear as though your device is the culprit. Identifying whether the issue is external or internal is crucial to finding the right fix.
2. Preliminary Steps Before Troubleshooting
Before diving into complex solutions, start with the basics. A few simple checks and resets may resolve the issue quickly:
Confirm the Correct Wi-Fi Network and Password
We often connect to multiple networks over time. Double-check your device’s network list to ensure you’re selecting the correct Wi-Fi SSID and using the right password.
