TP-Link LTE Router keeps disconnecting

Some customers might experience interruptions or disconnections with their 4G LTE routers, their phones or laptops can connect to the router wireless network fine, but they display a 'No internet' error, and customers cannot access the internet. This article aims to provide suggestions on the issue.

3. If the problem still exists, please insert the same SIM into another LTE device or even a smartphone, then monitor for some time to confirm if the internet works fine and is stable.

4. If the 4G signal in your area is strong and stable, please try to change the Network Type on Advanced->Network->Internet page from 4G Preferred to 4G Only to see if it would be more stable.
