This issue can appear if the network adapter doesn’t have the necessary drivers installed, but you can easily fix that by installing the drivers from the CD that you got with your network adapter.

Alternatively, you can also download the drivers directly from the manufacturer if you wish to do so. Usually, the manufacturer will have the latest drivers, so it might be better to you use them instead.

However, the simplest and quickest solution is to use a dedicated third-party driver updater and fixer like DriverFix.
