Purchased the device in late June. Upgraded to latest version as recommended by the UI.
I am using the router with gio SIM. And facing disconnection or very poor bandwidth issues. After reading other posts of band locking I upgraded to latest available version. When I try to manually select the bands from list of available bands from provider it fails with error. I tried selecting various combinations of bands none worked.
Questions I have are:
1. How is the band locking supposed to be used?
2. Why is automatic selection not working ?
