The RM500U-CN has issues when connecting to 5G

In my area, 5G NSA is on band N77. However, when I scan for 5G, I can’t detect it. When I used the firmware RM500UCNAAR03A05M2G_01.001.01.001 (sorry, I updated this firmware on my own after finding it on another forum), I was able to detect the 5G NSA signal on band N77, but I still couldn’t connect to 5G (here, 5G NSA is available on both band N41 and N77). That’s why I’m requesting the latest R03 firmware (I accept the risk, because I need to test 5G speed). Thank you very much for your support!

Dear @Nguyen_Anh
I have sent to your email, please check.

Once again, sorry to bother you. I would like to have a Web Commander (Web UI) interface to manage the card. Do you happen to have any firmware that supports this feature?

My card: RM500U-CN
Version: RM500UCNAAR03A12M2G

Thank you very much!

Dear @Nguyen_Anh
Sorry, we don’t have webUI.
