T420s F5521GW not connecting to Mobile Broadband, Drivers OK, Windows 10

Hello,

 

I have a ThinkPad T420S with Mobile Broadband Card – the  Ericsson F5521GW. The machine is on Windows 10.

 

PROBLEM:

 

Clicking on Network & Internet ->Cellular -> Connect button within Windows 10 will yield:

  • (Spinning dots) Connecting, then it just give you the Connect button again. No error message was thrown.

 

DIAGNOSTICS:

 

  • Running the command “netsh mbn show interface” showed correctly that F5521gw is the Mobile Broadband Interface
  • Cellular reported 77% reception
  • APN Setting was populated, and this setting used to work
  • F5521GW Firmware has been updated
  • Driver updated, windows reported no errors with the driver installed

Any help would be much appreciated

Dear nchow,

 

Welcome in lenovo community,

 

Since lenovo did not test or release the compatible windows 10 drivers for the T420s, My advice to you is to go back to the previous windows and check if the Mobile Broadband will work well or not.

 

Regards,

Joseph
