Look in device manager for any flags.
Get the latest drivers for the machine from the maker.

So for ages now my custom build PC has been having issues with the wifi. I'm using a TP link PCI-E wifi card. It really only works ok at times on one of my PCI slots. I don't know if the problems are to do with the wifi card or my mobo. I feel like I should know how to figure this out because I like to think I know my way around computers but any advice on how I could figure this out would help a lot. Thanks in advance!
