Model: TL-WR902AC  
Hardware Version: V3
Firmware Version: 0.9.1 0.4 v0089.0 Build 230223 Rel.5237n(4555)

Hi to everyone,

 

I have a problem connecting my TL-WR902AC v3 to USB 4G. The router recognizes my Huawei E3372h-320 LTE USB key but it always stops working within 24 hours with this error message:

 

1    2024-03-11 19:50:56    3G    Error    724: handle_card failed.
2    2024-03-11 19:50:55    3G    Error    690: after_switch not succeed error.
3    2024-03-11 19:50:24    3G    Error    724: handle_card failed.
4    2024-03-11 19:50:24    3G    Error    207: get card info error, before usb_modeswitch.

 

 

This solution is fixed older versions but not actually firmware.

Thank you very much in advance for your help

 

Best regards.Lucas

Hi, the issue in your case seems different since the USB modem can be detected and working for some time before it stops.

May I know if the internet will recover automatically after a while? or you have to restart the router or unplug and replug the USB modem?

 

Please connect the same USB modem to your computer directly and monitor if there is any similar issue.
