2. Connect to Wi-Fi. Go to Settings > Wi-Fi. Select your network (WPA2-Personal works best; enterprise networks may fail).
3. Check for updates. Tap "Software Update" on the main menu.
4. The 3160G will restart twice. This is normal. Do not touch the power button.
5. Installation time: Allow 25–45 minutes. The 2021 cumulative patch is large (~350MB).
