If your computer successfully connects to the WWAN but is facing issues accessing the internet, you should check if your computer can connect by using the LAN connection.
Before doing so, you need to disconnect the WWAN. Then, you can connect your computer using the local Ethernet connection (LAN).
- If your computer successfully connects to the internet using the LAN connection then you can connect with the WWAN service provider to fix the issue.
- But, if your computer did not connect to the internet using the LAN connection, you can troubleshoot the connection problem such as proxy, malware, firewall settings, or other settings that you think can prevent internet access.
