I recently updated my LG G3 and since then it hasn't been detecting wi-fi networks at my place or anywhere else. It was working perfectly before. What can I do to fix it without losing my photos and contacts?
Most likely the update left your network settings a bit broken, but without losing your data. First try restarting your phone completely and wait for it to boot up. Then go to Settings > Network & Internet > Wi-Fi, turn it off for a few seconds and turn it back on. Sometimes that's enough for the system to refresh and detect available networks.
If that doesn't work, try "forgetting" the networks you had saved. Go to Settings > Network & Internet > Wi-Fi > Saved networks, select your home network and tap "Forget". Then turn Wi-Fi back on and connect like it's the first time, entering the password. This often resolves conflicts that block the connection after updates.
As a last option before taking it in for repair, try restarting your router: turn it off completely for a minute and turn it back on. If none of this works, go to Settings > System > Recovery and choose "Reset network settings". This option only erases Wi-Fi, Bluetooth and mobile data configuration, but leaves your photos, contacts and apps intact. It's safer than a full factory reset of your phone.
Try resetting just the network settings without touching anything else: go to Settings > Apps > Show system apps, find "Wi-Fi Settings" (or something similar) and force stop + clear cache. That almost always fixes these issues after updates without losing anything. If it still doesn't work, go to Settings > Network > Wi-Fi, long press your network name, select "Forget" and reconnect by entering your password again 📱 - sometimes the update leaves a broken version of the previous connection saved.
After an update, the Wi-Fi module sometimes gets stuck in airplane mode without you noticing, so the first thing is to check the quick settings panel to make sure it's not turned on. If that doesn't work, go to Settings > System > Reset > Reset Wi-Fi, Bluetooth and mobile data, which is much safer than clearing system app caches because it doesn't touch anything related to your photos or contacts.
