Solved: Network connection in Windows breaks down


With some Windows computers, the problem regularly occurs that the network connection is suddenly no longer available.

Neither the Internet nor the router in the home network can then be reached. The other PCs in the network, however, can communicate as usual.

In many cases, the cause is the Ethernet adapter: The drivers in newer models offer a power management system which, by default, switches off the LAN chip during long breaks. In some cases this leads to the network failures described. To change these settings, open the Windows Device Manager. Click there on “Network adapter” and then double-click on the entry for the relevant Ethernet adapter.

The power saving feature of an Ethernet adapter sometimes leads to regular loss of network connectivity. But you can turn that off.

The power saving feature of an Ethernet adapter sometimes leads to regular loss of network connectivity. But you can turn that off.

Switch to the “Power Management” tab, uncheck “The computer can switch off the device to save energy” and close all windows with “OK”. In future, the driver will no longer be able to shut down the LAN adapter to save power, but network interruptions should also not occur.
