I have a mini PC by share (Chinese brand). The unit is much like an early NUC. I use this as a Home theater PC.
It has served me well until I began having problems with the integrated network interface. As a work-around I bought a couple of different USB to ethernet adapters which all seemed to be very slow giving me transfer rates in the 6Mb/s range
As I had several Mini PCI-e wireless cards laying around, and this has a mini PCI-e slot I thought I would go that route.
I purchased some internal laptop type antennas like the one on this page https://support.hp.com/za-en/document/c04851637
I notice that on that page the antenna sticks down with adhesive foil to what appears to be another shield. I assume the adhesive foil sticks to other metal/foil to form a Ground plane. Is this correct???
The "antenna" itself is the small PCB where the wire connects???
I am getting very slow throughput and have now purchased various antennas and have had no luck so far. I have also tried different wifi cards .
I should mention this is a mostly plastic case with aluminum top cover.
Anyone have any knowledge of internal laptop type wireless antennas?
