# WIN gateway stops on Teltonika routers

Teltonika routers have an undesired “feature” in them that can halt all communication from a WIN gateway in certain situations.

If the WIN gateway communicates frequently with the Teltonika router (i.e. with less than 5 minutes between posts) there is no problem, but when the time between posts is longer than 5 minutes then Teltonika router ignores the WIN gateway.

To create a work around the WIN gateway has a feature added called [Periodic Ping Reset](/win-gateway-installation-manual/gateway-configuration/periodic-ping-reset.md) where the WIN gateway pings the router i.e. the IP defined as the network gateway in the network settings every minute and if it fails to get a reply 3 times in a row, it restarts the WIN gateway. As the PING is only local on LAN, between the WIN gateway and the Teltonika router, there is no additional mobile traffic due to this feature being activated. The Periodic Ping Reset is turned on by default but can be turned off in case the WIN gateway is installed in a customer’s network and customer IT representative doesn’t want any additional traffic in their network.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.boomerang3.com/win-gateway-installation-manual/troubleshooting/win-gateway-stops-on-teltonika-routers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
