Regarding the wifi signal issue, as you mentioned, the wifi reception has relation with the distance between the unit and the router. It does not matter with the firmware and the usb wifi device when the unit could receive wifi signal.
You may try a way sharing from one of our clients as the below. Hope some help.
"I just used an typical wifi antenna from an old router and brazed it on same point as the old antenna was
i did not remove the old antenna just added a second one on the old antenna output, works really good"
