Hello @TaufikMaggangka ,
DirectQuery mode means your Power BI file doesn't store any data. Every time someone opens the reports, changes a slicer or selects for example a bar of a bar chart, a query will be sent to the data source.
For that reason the data source must be available at all times.
If you use a data source that is in the cloud, like an Azure SQL Server database, Power BI Service can just connect directly to the data base in the cloud.
In your case you are using a data source that is in your network. As the Power BI Service is not in your network a gateway is required to access the service. When someone opens a report in Power BI Service, the query is sent to the gateway in your network and the gateway will then grab the required data from the source and send it to Power BI Service.
In general it's not recommended to install the gateway to a normal notebook. As you said, when you are not online, nobody is able to access the report. In general it's recommended to install a gateway to a server that is running 24/7 in your company. Also it's recommended to install at least 2 gateways to 2 different machines as this one machine would be the bottleneck again.
To come back to your question:
a) Switch to a data source that is always available in the cloud like Azure SQL database, files in OneDrive and so on.
b) DirectQuery mode has a lot of disadvantages. Is there a specific reason why you need direct query mode? Otherwise just import the data. Like this most of your problems would be gone.
c) Install the gateway on a server or a notebook in your environment that is always on
If you need any help please let me know.
