Unpair the device if connected anywhere. Update the pc's outdated drivers. 
Hi there, I have noticed that that my Mobile Hotspot feature stops working on 5 GHZ band in windows 10 whenever the Qualcomm Wifi drivers are updated. I don't know where I can report this issue so I am attaching the screenshot here and asking the community for suggestions so that this issue can be fixed in the next update. The driver is: Qualcomm QCA9377 802.11 ac wireless adaptor The below version are from device manager. Problem version: 12.0.0.1118, Date: 6/15/2021 Working version: 12.0.0.722, Date: 8/22/2018 Currently I am using the rollback feature whenever it stops working as it only stops working when it auto updates.
