Suddenly wi fi will not turn on

There could be several reasons why your Verizon tablet keeps disconnecting from Wi-Fi and not accepting your password to reconnect. Here are some possible solutions:

1. Restart your tablet and your Wi-Fi router: Sometimes, simply restarting your tablet and router can help resolve connectivity issues.
2. Check your Wi-Fi signal strength: Weak Wi-Fi signal strength can cause frequent disconnections. Move closer to the router or try to improve the signal strength by repositioning the router or using a Wi-Fi signal booster.
3. Check your Wi-Fi network settings: Check if your Wi-Fi network settings match those of your router. Make sure you have the correct security settings and password. Try to forget the network and then reconnect and re-enter your password.
4. Clear your tablet's cache: Clearing your tablet's cache can sometimes help with connectivity issues. You can do this by going to Settings > Storage > Cached data > Clear cached data.
5. Check for software updates: Make sure that your tablet is running the latest software updates. Check for updates in Settings > System updates.
6. Factory reset: As a last resort, you can try doing a factory reset on your tablet. This will erase all data on the tablet, so make sure to back up any important files before doing this. Go to Settings > Backup & reset > Factory data reset.

If none of these solutions work, you may want to contact Verizon customer support for further assistance.
