RM500Q-GL Latest Driver

Device: RM500Q-GL

Firmware: RM500QGLABR11A06M4G_01.200.01.200

Previously, OAI 5G communications were good. However, when I make an OAI connection now, the error ‘unserviceable’ appears, so 5G connection is not possible.
I am using the ‘Quectel_Windows_USB_Driver(Q)_NDIS_V2.6.0’ driver. Do you happen to have more recent drivers?

Thank you.
