@asyal and @dfrey, I went with your suggestion and purchased the IoT WiFi Card. Unfortunately, the board is failing to start and the LED is not powering on: The issue is that the wifi board is simply not being found/powered. This is happening on all of our Reds. It DOES work on the Green. But it is very important that it works on the red. What could be the issue? > root@swi-mdm9x15:~# wifi client start > successfully called start. //Not actually starting > root@swi-mdm9x15:~# app status > [running] atClient > [running] atServer > [running] audioService > [running] avcService > [running] cellNetService > [running] dataConnectionService > [running] fwupdateService > [running] gpioService > [running] modemService > [running] positioningService > [running] powerMgr > [running] secStore > [stopped] smsInboxService > [stopped] spiService > [stopped] tools > [stopped] voiceCallService > [stopped] wifi . //Not running > [stopped] wifiApTest > [stopped] wifiClientTest > [running] wifiService > [stopped] wifiWebAp According the wifi driver tutorial here: [http://mangoh.io/wifi-expansion-card](http://mangoh.io/wifi-expansion-card) states “The Wi-Fi LED on the Wi-Fi expansion card turns ON” - This is not the case. There is no indication that the command worked, as the app is off and the light is not on. Passing this, I perform the next step “wifi client scan” and get the following result: starting scan.

Do you have any idea why the IoT expansion card is not starting properly on the MangohRed? Just for clarification, the Versions are up to date according to the tutorial(although it is a mangoh Green tutorial): > root@swi-mdm9x15:~# fwupdate query > Connecting to service … > Firmware Version: SWI9X15Y\_07.12.09.00 r34123 CARMD-EV-FRMWR1 2017/04/26 23:34:19 > Bootloader Version: SWI9X15Y\_07.12.09.00 r34123 CARMD-EV-FRMWR1 2017/04/26 23:34:19 > Linux Version: 3.14.29ltsi-961ca71325\_ab5094eade #2 PREEMPT Thu Apr 27 02:17:10 PDT 2017 > root@swi-mdm9x15:~# legato version > 16.10.3\_7776bb75a488e0db67b0d24975b46dd0 I believe it comes down to the wifi board not being recognized on the Red. Any suggestions? Thanks! --- _[View the full topic](https://mangoh.discourse.group/t/usb-driver-failing-to-find-or-power-usbs/1033)._
