            @seannyboy08 Are you sure that your WiFi is now working (i.e. you've set the WiFi country) ? What's the output of the following command:

            iwconfig wlan0

              When I type in iwconfig this is the outcome -

              lo no wireless extensions.

              enxb827ebf18d83 no wireless extensions.

              Do I need to get a new raspberry pi and replace the microprocessor ?

                  iwconfig doesn't list your WiFi interface - it may not be enabled. Did you use raspi-config to set the WiFi country, as advised ?

                  The interface name for the wired interface is also not something that's present on a RetroPie or Raspberry Pi OS image - what image did you use to install the system ?

                  Do I need to get a new raspberry pi and replace the microprocessor ?

                  I don't think so.

                    When I run raspi-config and go to localization settings then WLAN Country it says this -

                    no wireless interface found
                    and then on the next page after I press ok it says this -

                    There was an error running option L4 WLAN Country
                    and then the only option again is to press OK ?

                          Literally the image file you asked me to download from scratch but if you think its the image file got currupted during the writing process i'll try again or is there another image file you recommend ?

                          This was your words -

                          We don't support 3rd party images - use the image from retropie.org.uk/download and we can help

                            @seannyboy08 I think he's more interested in making sure you grabbed the right image for your hardware. You should have downloaded the rpi2/3 image (assuming this is still the Pi 3b in your post above).

                              In this case I don't understand why the WiFi is completely disabled or not present. Can you post the contents of the config.txt configuration file from the sdcard, should be accessible if you insert the sdcard into your PC from the boot partition that shows up.

                                        @seannyboy08 I don't think being out of range is the issue here - your WiFI interface is not working on the Pi, before even trying out to connect to an access point (which may or may be not out of range).

                                        Can you run the following commands and post the output:

                                        iw reg get
                                        rfkill list all
                                        systemctl status wpa_supplicant
