On board wifi card?PCI/PCI-E or you meant the one integrated into the motherboard?Cause the latter won't come cheap.

For 2.6K,change Mobo to Asrock H97M-Pro4 RM299 and Wifi to TP-Link WN881ND RM49.The Wifi in 2.5K is USB,because B85M-HDS doesn't have any PCI or PCI-E lanes other than one for the GPU.

Samsung S22C170BS you sure is IPS? and can change the USB wireless Adapter to PCIE wireless card?
