Lenovo x301, Access Connections, and Ericsson F3507g Mobile Broadband MiniCard

I’m a happy owner of the Lenovo x301, but starting a few days ago, the Ericsson F3507g suddenly disapeared from the Device Manager, and Access Connections had the Mobile Connections selection button greyed and disabled. Also, if I tried editing the existing Mobile Broadband location profile, and wanted to edit det F3507g network card settings, I got a message stating that the network card was not found.

I tried following the post at the Team Mobile Blog¬†– and yes I did know that my laptop wasn’t a W500. Also note, that I did not upgrade fra Windows Vista, I did a fresh install. But i figured that trying the steps described couldn’t do any additional damage.

After following the steps, nothing was any different. The device was still undetected in Device Manager, and ofcourse, Access Connections didn’t allow me to choose my Mobile Broadband location profile.

I don’t know what made me try this, but it worked. I rebooted, went into the BIOS, disabled the Wireless WAN networking, saved the settings and exited. I then went straight back into the BIOS, reenabled the Wireless WAN networking, saved the settings and exited. Booted back into Windows 7, and guess what – the device detection found my Ericsson F3507g Network card. Now, the last device detection failed, but that didn’t seem to matter as everything worked fine after another reboot.

I sure hope this helps some of you, as it was quite frustrating not being able to use the mobile broadband connection.

    I have this exact problem on an X301 / Windows 7 – since this morning there is no trace of the ericsson card (I normally use it every day on the train). Have spent a good few hours trying to work it out now. I just dropped into the BIOS to try your recommendation but I can’t see an option for Wireless WAN in there (does it appear in your BIOS under networking?) Surely it can’t have disappeared from my BIOS too…

      Hi Jon,

      I’m sorry for this late reply but I simply missed your comment.

      You’ll need to go into the BIOS, select Security, and then I/O Port Access. Here you can disable and enable multiple devices.

      Also, you may have to reset the BIOS Defaults.

      I Hope this helps.
