Can you please log in the router, then go to the Wireless option, then make sure the Authentication Method is set to WPA-Auto-Personal (or choose the option that has both WPA and WPA2), and the option WPA Encryption is set to TKIP+AES, then Apply / OK. Then try connecting the tablet and check.
- If needed, press and hold the power on/off button on the tablet, then select the Restart option and confirm, then connect the tablet to your wireless network name, and check. (If it has the forget option when tapping on your network name, then select the forget option, then tap on your network name again, and connect.)
- If needed, update the router's firmware if it's not updated yet:
- If needed, can you test connecting the option Authentication Method to Open System (or Disabled or None, etc.), then apply/ok, and check? Then test with different authentication method and apply, and check.
