Everything seems to be working fine except only with ethernet. I made the WiFi changes in the setup screen ( SSID, PW) saved it ,but after rebooting if I go back and check the changes don’t seem to have been changed.  
I SSH’d into the Rasp Pi ( 3 +) and tried to change the wsa\_supplicant file but if I make changes it won’t allow me to overwrite the file with the changes. I removed the SD card and tried to read on my PC desktop but it won’t read the card.  
Any help would be much appreciated.

I changed the wpa\_supplicant.conf.bak ( couldn’t find the wpa\_supplicant.conf file in the boot directory) put in my SSID and PW .Saved file then Rebooted. Still no WiFi.  
The location that I want to place my ADS-B Rx does not have ethernet connectivity hence the need for the WiFi.  
tnx

Turns out my Rasp Pi B+ doesn’t have a WiFi adaptor. Added one to one of the USB ports and now WiFi works. Now to snag my first plane 🙂
