The internet LED indicator 
does not light solid on. What should I do?
Try the following solutions:
1.Check that your SIM card supports LTE or WCDMA.
2.Check that your SIM card is in your ISP’s service area.
3.Check that your SIM card balance is sufficient.
4.Start a web browser on the device connected to the router, and access //tendawifi.com. You will be redirected to the troubleshooting page. Then, perform troubleshooting as prompted on the page.
5.Confirm with your ISP if you are in a roaming service area. If yes, log in to the web UI of the router and navigate to Internet Settings to enable Data Roaming.
