iv recently disassembled my old laptop and taken out the pcie mini card but my PC motherboard is a pcie 2.0 slot which is smaller than the card is there any converters out there that I can use to plug it into my PC?
so would it be cheaper to get a wireless card instead then?
Yes, PCI/PCIe adapters are cheaper and more reliable than using an adapter to a different slot device like mPCIe. The cheapest wireless adapters are also the easiest to install: USB. And they work fine.
