It will not stay connected to the Wi-fi. It will not allow me to download any apps because it states their is a server error problem. It is virtually useless to me. I purchased two for Christmas and neither of them work. I am frustrated and ready to send it back. To that end, it states it can't locate a driver for it on my pc. Any suggestions that can fix these problems. I really would like to keep them. But, not if they are useless.

What are you using Wi-Fi for? You may have Wi-Fi but your Wi-Fi it may not be hooked up to the Internet. Try restarting your Wi-Fi / router.

The free Wi Fi router may have run out of IP leases on its DHCP server just when you were trying to connect the tablet. If the leases are as an example say one week long then if lots of people connect to the free wi fi they get a lease for one week. So if the device comes back within the week it already has an IP address assigned to it and works. If a new device comes along it has to ask the DHCP server via the WI FI to assign it an IP address. If all available IP addresses are leased from the WI FI router the device will not get assigned an ip address. Would suggest trying to connect the Tablet on another Wi FI system to test it works.
I had this happen on my mobile phone when I was in Surfers Paradise in a Coffee shop and suspected the lease time on the WI FI router was too long for the amount of short term customers using the coffee shop. (the staff had no idea on why the Wi FI was not working so it would have been pointless to try and explain this concept to them and how to change the lease time on the dhcp server) Also there is a limit to the simultaneous number of users on a Wi Fi frequency on one access point . Unless the WI FI uses multiple WI FI access points.

Solution 1.Check wireless connection.
The first step of diagnosis have to any other device connected to the same network, ensure the wireless connection is working fine, or verify the settings of your wireless router to correct it.
2.Check your Keep Wi-Fi on during sleep Settings.

Tweak this policy to keep your Wi-Fi connection awake.

Save changes and exit all the screens. Your Wi-Fi will never get disconnected again due to this policy.

The performance of a wireless network connection depends in part on signal strength.
You have to connect the Wireless network where the signal strength is strong.

Third-party programs might be the major probability of Tablet/Phone instable, suggested to have a full reset for the device if the situation persists.

no es un problema en el wii fii es un virus que fue descargado en alguna app prueba conun antivirus de la android store

Thank you for the Video, this made it much easier for me to determine the problem. You are correct, you have WiFi, this is not the problem, the problem is with the Tablet's WiFi Service which is freezing, thus not causing you to access WiFi.

Have you installed any new software lately? Something has broken the WiFi software on your Tablet. If you installed a new App recently, remove it to see if that new App broke your WiFi software on your Tablet. If you have not installed anything new on the Tablet maybe the manufacture downloaded an update that broke the WiFi on the Tablet. If you recently received an Software update from the manufature, let perform a Factory Resetr on the tablet to fix the issue.
