Thanks, We plan to put a Netgear WPN311 in place.
Oddly it fits but it appears there is about 3/8th of an inch extra space in the slot.
Does that make any sense? Is it common for there to be open space in a PC slot?
Get a $20 USB WIFI adapter. This model with windows 8 or 10 is plug and play without needing to install any drivers.
