Hello everyone,

I’m using XR90, and I noticed that WebUI is not displaying correct band that unit is connected to.  
It is set to 3G technology, and WebUI shows Band 3. However, in my area, 3G uses Band 1

Has anyone experienced similar issue with XR90?

Hi @callista,

Could you please answer the questions below to investigate the issue:

1. Could you please share a screenshot of Cellular Configuration/Cellular Status?
2. Please go to System \> Logs \> Regular log, select download and share regular log file of the XR90 with me.

Besides, I will try to reproduce the issue on my side and let you know the result.

Thanks,

Hi @callista,

My device is currently running AirLink OS 6.1.0.37 and I haven’t encountered the issue you described. If you are using an older AirLink OS version, could you please try upgrading to AirLink OS 6.1.0.37 and check if the issue still occurs?  
Please refer to [source.sierrawireless.com/resources/airlink/software\_downloads/xr90/xr90-firmware-list/](https://source.sierrawireless.com/resources/airlink/software_downloads/xr90/xr90-firmware-list/#sthash.56eadf2Z.dpbs)

Thanks,
