Microsoft released an updated version: https://www.microsoft.com/en-us/download/details.aspx?id=57439
Same es above applies, but in netathr10x.inf DriverVer = 08/24/2018,12.0.0.722 (new one SurfaceGo_Win10_17134_1803010_WiFi_0.msi) instead of DriverVer = 06/04/2018,12.0.0.709 (old one SurfaceGo_Win10_17134_1802010_6.msi) is listed. Also the md5sum of the .bins have changed, see: old one: pink@debian-470t:~/Dokumente/surface_go_wifi/extracted_msi/SurfacePlatf ormInstaller17134_1802010_6/Drivers/Network/WiFi$ md5sum eeprom_ar6320_3p0_TX8_clpc.bin fcbc54a33a3ee462d862fe4f62854410 eeprom_ar6320_3p0_TX8_clpc.bin new one: pink@debian-t470:~/Dokumente/surface_go_wifi/extracted_msi/SurfacePlatf ormInstaller_17134_1803010/SurfaceUpdate/Drivers/Network/WiFi$ md5sum eeprom_ar6320_3p0_TX8_clpc.bin bc52aa5640b27fa50f9d4d144f81e169 eeprom_ar6320_3p0_TX8_clpc.bin So the driver should be extracted now from SurfaceGo_Win10_17134_1803010_WiFi_0.msi I think. I will attach the new one here which should now be used instead to add to board-2.bin Also one with lte in the name is listed: pink@debian-t470:~/Dokumente/surface_go_wifi/extracted_msi/SurfacePlatf ormInstaller_17134_1803010/SurfaceUpdate/Drivers/Network/WiFi$ md5sum eeprom_ar6320_3p0_TX8_lte_clpc.bin 8f2895dd63a0c8f11e2d051f0ed4e0a8 eeprom_ar6320_3p0_TX8_lte_clpc.bin I will also at this one, but I can not confirm, that it is for the LTE version because I just own the wifi one so I can not check the IDs, but maybe others can do.
