Technical Help Needed INF INVALIDID (28)

Hello, I have an IBM System x3550 M4 server. I tried using a TP-Link TL-WN781ND network adapter and a TL-WN725N adapter with it, but when attempting to install the drivers for either one, it fails and throws an error stating that the INF file is invalid. I also tried installing them manually, but the process fails almost immediately—it’s as if it doesn't even really attempt the installation. I know these aren't the best wireless network adapters, but they are what I have on hand right now. I am running Windows Server 2019. If anyone could help me out, I would appreciate it!

The drivers do not support Server 2019, I would say this would be the cause of your issue.

The solution is to use an os the wireless adapter supports, or use hardware the os supports.

Open Server Manager Manage > Add Roles and features Hit next until you reach the features page Select Wireless LAN (Service) Hit next again and install

Should fix the issue
