Server 2016 – A service installation section in this INF is invalid

After adding a PCI wireless card to a server and installing the manufacturer drivers it will not work and Device Manager reports Unknown device and the drivers are not installed with a “Service installation section in this INF is invalid” message.

Turns out the wireless features are not installed by default on Windows Servers now and once added back re-add the manufacturer drivers as normal to get working again.

Enabling wireless on Server 2012 R2

I needed to get wireless working on my new home lab server a HP Microserver Gen8 with TP-Link TL-WN781ND PCIe wireless card. It wouldn’t work.  Having worked with servers for years I’ve never used wireless NICs in them and didn’t realise you have to add the wireless feature beforehand but works fine afterwards.
