When your device won’t join the network, it’s usually something small, not a major outage. The good news: most Wi‑Fi issues can be fixed in minutes with a few checks you can do yourself. This guide walks you through the five fastest solutions that solve the vast majority of “can’t connect to WiFi” problems. Follow them in order, and you’ll know whether the issue is on your device, your router, or your internet provider.
1) Restart the right way
A proper restart clears stuck processes and renews your connection. Start with your device: toggle Wi‑Fi off and on, then fully restart the device. Next, power‑cycle your network gear. Restart the router (and modem, if they are not the same device) by disconnecting the power for half a minute. After 30 seconds, reconnect the modem and wait for its indicator lights to become steady before plugging the router back in. Plug the router in last and give it two minutes to boot. Finally, stand near the router and try connecting again. This sequence forces a clean handshake between your device, router, and your internet service.
2) Check the simple settings
Small settings often cause big headaches. Ensure that your device’s Airplane Mode is disabled and its Wi-Fi is enabled. Confirm you’re choosing the correct network name (SSID) and typing the password exactly, paying attention to capital letters and special characters. If you recently changed the password, tap “Forget” on the network and reconnect from scratch. Try both bands if you see them: 2.4 GHz reaches farther and handles walls better, while 5 GHz is faster at close range. If the network is hidden, add it manually with the exact SSID and security type. These basics fix many “authentication error” messages instantly.
3) Get a fresh IP and fix DNS
If you’re stuck on “Obtaining IP address” or connected but have no internet, refresh your network details. Turn Wi‑Fi off and back on to request a new IP from the router. On laptops, you can renew your lease in the network settings; on phones, toggling Wi‑Fi usually does the trick. If websites won’t load but apps work, or you can ping a site by number but not by name, switch DNS to a reliable public option like 1.1.1.1 or 8.8.8.8 in your network’s advanced settings. Flushing DNS or clearing “Private DNS” overrides can also resolve name‑lookup failures. After changes, reconnect and test a few sites.
4) Inspect the router and the environment
Your router’s lights tell a story. If the internet or WAN light is off or red, the issue may be upstream—check your provider’s status page or app. If Wi‑Fi lights look normal but your device still fails to connect, move closer to the router to rule out weak signal or interference. Thick walls, microwaves, cordless phones, and crowded apartment buildings can all disrupt wireless signals. Try a different room, temporarily disable any “MAC address filtering,” and ensure your router isn’t limited to a mode your device doesn’t support. If you have both 2.4 and 5 GHz networks, test each and see which is more stable in your space.

5) Update software and reset cleanly
Out‑of‑date software can cause compatibility issues. Update your device’s operating system and, if on a computer, the Wi‑Fi adapter driver. Log into your router’s admin page and apply the latest firmware from the manufacturer; this often improves stability and security. If problems persist, perform a network reset on your device to clear old profiles and settings, then reconnect as new. As a last resort, back up your router configuration and do a factory reset to remove corrupt settings. Recreate your SSID and password, test with one device first, then bring other devices back one by one to spot any conflicts.
When it’s still not working
At this point you’ve ruled out the common culprits. Try a wired connection from a laptop to the router; if wired also fails, the problem is likely with your modem or internet provider. If wired works but Wi‑Fi doesn’t, the router’s wireless radio may be failing. Contact your ISP for a line test or swap in a different router to isolate the issue. If only one device refuses to connect anywhere, that device’s Wi‑Fi hardware may need service.
Prevent the next outage
A few habits keep Wi‑Fi smooth. Place your router in a central, elevated spot away from clutter and appliances. Use a strong, unique password and modern security (WPA2 or WPA3), and keep firmware and device updates current. For large or multi-level homes, consider using a mesh network to eliminate areas without Wi-Fi coverage. Finally, set a simple label or note with your SSID and password so guests stop creating duplicate hotspots that confuse your devices.
Staying calm and working through these five quick fixes solves most connection problems without a long support call. With a clean restart, correct settings, fresh network details, a healthy router, and up‑to‑date software, your Wi‑Fi should be back online—and more reliable going forward.
