If the tablet shows you that you have the wrong DNS server settings, or you can't connect to WiFi, you need to adjust the DNS server settings. Here's how to do it:
1) Open settings in tablet and follow flow below:
- WLAN (Wi-Fi - networks) - select a specific network (hold) - Connect or Edit network
2) Choose Edit network: - select IP address settings - select the Static option
3) Choose Advanced options (click):
IP address - you need to find your IP address in Settings - System - Tablet information - Status - IP address - in most cases have the format as follows: 192.168...
After you put the right IP address, set up DNS server 1 or 2. You can pick just one.
DNS Server 1: 22.214.171.124
DNS Server 2: 126.96.36.199 (or 188.8.131.52.)
Save. That should be done. Your WiFi connection should renew.
