Dirty Screen ¶ 

Make sure the screen is clean, using a damp (lint-free) cloth. Do not spray the screen with water or solution, spray liquids onto the cleaning cloth only.

Damaged Screen Protector ¶ 

Visually inspect your screen protector for damage. If you have a screen protector on your tablet and it looks damaged, try removing it. Also, screen protectors can sometimes interfere with the sensitivity of the touch screen. (note-some screen protectors can only be used one time and may not be reusable)

Not Enough RAM ¶ 

Shut down the device and restart. Restarting the device may close down applications that are running, freeing up Random Access Memory (RAM) that may be slowing down the device. If the restart does not resolve the issue, try a device reset. Locate the reset button (the reset button is located next to the SD card slot on the back of the tablet) and reset the device. Make sure to save any work you have on the device before resetting.

Open the settings and make sure the mute setting is off. The volume could be very low or off. Use the up volume button on the bottom of the tablet.

Software Problem ¶ 

If the volume is up and the mute settings are off, there may be a problem with the software that can be fixed with a factory reset. To perform a factory reset, insert a paperclip into the small hole on the back side of the tablet that is labeled reset (next to the SD card reader) and hold the power button for 10 seconds at the same time. This will prompt an options screen, scroll down with the volume buttons and select with the power button “Wipe Data/Factory Reset” . Then use the volume keys to choose “Yes” and the power button to select, then select “Reboot System Now” with the power button. This will clear all data from the tablet so make sure to store your files from the tablet somewhere else before attempting to reset.

Router Or Modem Proximity Issues ¶ 

You may be having problems with connecting to the Wi-Fi simply because you are not close enough to the router and/or modem, there may be obstacles between the device and the router and/or modem, or there may be interference with other devices that use a 2.4GHz frequency band, such as a microwave, Bluetooth, or digital cordless devices. Simply move closer to your router and/or modem and try again to connect to the Wi-Fi

Router Or Modem Connection Issues ¶ 

You may be experiencing problems with connecting to the Wi-Fi because the router and/or modem is simply not on. Ensure the router and/or modem is on and check your connection.

If the router and/or modem is on it may need to be restarted. Simply turn off the router and/or modem, wait 30 seconds, and turn the router and/or modem on.

If you still cannot connect to Wi-Fi and your router and/or modem is broadcasting a signal, perform a soft rest on the tablet. A soft reset can be performed by holding the power button for 2 seconds, the screen will display “power off”, select “ok” to power off the unit completely. Wait 30 seconds, then push the power button for approximately 2 seconds and the device will start up again. After giving the device a minute or so to start up, connect to the Wi-Fi.

If the router and/or modem is still not sending out a signal after a reset, contact your internet provider.

Software Problems ¶ 

If after trying the steps above doesn’t work, resetting the device to factory settings may help. When this is done all of the user settings and data will be lost, so make sure that all files are saved to another device so that they are not lost. To do this press the power key, volume +, and volume - keys all at the same time for about 6 seconds. Using the volume keys, select “wipe data/factory reset” and press the power key to confirm the selection. Select “Yes- delete all user data” and press the power key to confirm the selection. Finally the screen will show “reboot system now”. Press the power key to confirm and then device will reboot and then open the home page.

Defective Motherboard ¶ 

After going through all of the above steps (multiple times if possible), there is the chance that the wireless receiver may be malfunctioning and the motherboard may need to be replaced.
