Hi,

I have a Windows machine with three RM500Q-AE modems. They’re recognized in the device manager and respond to AT commands, but they won’t connect to the network or acquire an IP address.

Serial numbers and firmware:

  • 867197051081590
  • 867197051083165
  • 867197051082291
  • Firmware: RM500QAEAAR11A03M4G

Could you provide a different driver or instructions to enable the connection?

Urgent assistance needed. Thanks!

I’m using PCI board for connecting each modem to the motherboard

Hello,

I’ve successfully managed to connect three modems, and they are now functioning. However, two issues have arisen:

  1. Modem Connectivity and IP Issue:
  • Modem 2 connects automatically and acquires an IP address without any problems.
  • Modem 1, however, is encountering difficulties connecting.It appears that when all modems are disabled and then enabled individually, all three modems connect as expected.
  1. APN Configuration on Windows 11:
  • As I am using Windows 11, I’m encountering a challenge. There isn’t an apparent method to configure the Access Point Name (APN) details, such as the APN name, username, or password for the modem.
  • I possess access to AT commands, but I’m uncertain about how to proceed with making the necessary changes.

These issues are causing a hindrance to my desired connectivity. I’m seeking guidance and assistance in resolving these matters effectively. Thank you for your assistance.
