The Wi-Fi hotspot may not appear to be working on some 2018 Sonic, Trax, and Terrain models equipped with infotainment system RPO IOR (3.X Low HMI, Midlevel Connectivity 3.X).
On infotainment system RPO IOR, there are two settings that must be turned on in order for the Wi-Fi hotspot to be enabled as well as to share data with a connected device. Owners may have turned on the Wi-Fi hotspot without activating the sharing data function.
From the infotainment system Home screen, go to Settings > System > Wi-Fi Hotspot. (Fig. 13)
Select Wi-Fi Services under the Wi-Fi Hotspot menu to turn on the Wi-Fi hotspot. The On indicator will be green when the setting is turned on. (Fig. 14)
Scroll down in the Wi-Fi- Hotspot menu to select Share Hotspot Data to activate the sharing data function. The On indicator will be green when the setting is turned on. (Fig. 15)
Check that both of these settings are turned on if there is a concern regarding the functionality of the Wi-Fi hotspot before pursuing additional diagnostics or repairs.
