1. Check the signal strength of the Wingle and confirm whether it is caused by network signal instability or poor signal quality.

2. Clear your browser temporarily and close anti-virus software, firewalls and proxy settings and try to open the webpage again.

3. Restart the Wingle and computer, and try again after reconnecting.

4. Put the SIM card into a phone and check whether you can use the data. If your SIM card is not available on your phone, please consult the network operator. If data works with your mobile phone, please try to restore to factory settings (Note: restoring to factory settings will clear your address book and short messages, please backup your data before doing it).

5. If your issue still persists, please contact after-sales services to solve the problem.
