How to get Ericsson F3507g Mobile Broadband card working on Windows 7 & Lenovo Thinkpad T400s

Update: A new driver has been released which uses the Windows 7 Mobile Broadband driver framework. Please see my new article. Note: Information and comments on this article could still be relevant to you so read on…

I recently purchased a Lenovo Thinkpad T400s. I installed Windows 7 on it soon after, having heard that almost all hardware devices worked under Windows 7. For me it was crucial that the Ericsson F3507G internal mobile broadband card worked, and luckily there was a driver for it available on Lenovo’s Windows 7 “Beta” drivers

God knows what a "Drever" is!

First thing to note is that even though it says “32-bit”, inside the zip there are actually 64-bit drivers as well. Phew! Unfortunately it seems that versions and publish dates are not supported by Lenovo’s knowledge base, so all we get is a crazy looking file name –

After you install this driver you will have several new devices available in Device Manager:

  • Ericsson F3507g Mobile Broadband Minicard Network Adapter
  • Ericsson F3507g Mobile Broadband Minicard Modem
  • Ericsson F3507g Mobile Broadband Minicard Device Management (COM3)
  • Ericsson F3507g Mobile Broadband Minicard GPS Port (COM6)
  • Ericsson F3507g Mobile Broadband Minicard PC SC Port
  • Ericsson F3507g Mobile Broadband Minicard Composite Device

I am not a big fan of using OEM software over what comes with Windows, as it’s invariably crap. Lenovos’s network manager tool is called Access Connections and I would later discover my intuition would prove to be well founded.

So at this point I decided to try using the device as a dial up modem, by using “Create a Dial-up Connection”, then picking one of the two modems that show up (never worked out what the difference was).

Create a Dial-up Connection dialog

The problem is it will then ask you for a Dial-up phone number, and various other fields wholly inappropriate for a 3G WWAN card. After a bit of googling I worked out that you should use *99***1# in the phone number field (*99# may also “work”), and leave the user name and password fields blank.

Create a Dial-up Connection details

The problem was after connecting I would get “Error 734: The PPP link control protocol was terminated”

Error 734: The PPP Link control protocol was terminated

Now there was a setting I definitely knew I needed to put in somewhere, because all 3G modems require an APN… but there is no self-evident place to put this setting (remember basically we are trying to use a piece of 2009 technology with a modem interface designed probably 30 or 40 years ago!). After a bit of hunting around it turns out that you can put this setting in the “Extra Initialization commands”. Not the easiest thing to find but its located in Phone and Modem –> Properties –>Advanced dialog.

The string to set the APN is some variant of


where dodolns1 is your broadband provider’s APN.

Even after figuring this out I would still get the Error 734 message! Bah!

Lenovo Access Connections = No Good

At this point I gave up and decided to try using the Beta version of Access Connections. I downloaded the “” version. I installed it and it worked.

Kind of.

Now I am all for OEM’s giving early access to software, but unfortunately Access Connections is no where near “Beta” standard. “Beta” in this case just seems to just be a label for lazy and poorly tested code. There are at least 3 huge bugs with Access Connections for Windows 7:

  • A memory leak that causes explorer.exe to consume 900MB of RAM every 20 hours or so. At which point explorer would stop working, and I would have to kill and restart it. For a bug as huge as that to be released into the public, no matter what label you give it, is a sign of a rotten development process.
  • It constantly forgets your customised APN settings. So each time I wanted to connect I would have to delve into the settings and enter them again.
  • The WWAN connection it created for me was generally unreliably and would drop IP connectivity every 5-30 minutes (the wireless/PHY link would be fine, just the IP stack would stop working).
  • It could, and often would, take ages to connect.
  • Performance was pretty sluggish – it would take ages to load the main interface. All I want is for my broadband card to work!

I lived with this situation for a few weeks, but today I couldn’t handle it any more. I uninstalled Access Connections and will probably never use it again. As I said OEM software is invariably crap and this “Beta” was no exception.

The Solution – Sony Ericsson Wireless Manager

I have to credit some posters on Thinkpads Forum for the final, and only, solution I was happy with.

Basically you just have to download a tentatively related piece of software from Sony Ericsson, called “Wireless Manager” which they claim is for an apparently unrelated card, the EC400g.

Both links get you to the same software. Nowhere does it mention that the F3507g card is supported, but I can confirm it does work using version 5.2.2056.12.

The filename I downloaded was

After downloading and unzipping it, you just need to run “Sony Ericsson Wireless Manager 5.msi” which can be found inside the Install folder:

After that completes it will say something about “to install drivers, please click next”. Suffice to say that it just stops at this point and no drivers get installed. When you load it up you will be presented with this:

Wireless Manager UI, with setting button highlighted

The first thing to do is click the spanner to setup your APN. (You may not have to do this – it depends on whether your provider is known in the standard list).

Creating a new profile in Wireless Manager

For my provider, Dodo, I had to untick the “Let Wireless Manager Choose the Connection Profile” and then I created a new profile, and put the Access Point Name (APN) in as shown above.

You then click “Enable Radio” and wait while it detects the mobile networks (hopefully including yours). If that is succesful you just press the big “Connect” button and you are online!

One great feature about this is that once the radio is enabled you have two ways of getting online. You can either use:

  • The Wireless Manager connect button which activates the Ericsson F3507g Mobile Broadband Network Adapter (which means you don’t have to mess about with any dial-up stuff)
  • Or you can use the RAS/Dial-up connection that Wireless Manager creates (It created one for me called WirelessManagerRasConnection).

What is strange is that you can have both of them connected at the same time. I have yet to work out if that has a detrimental effect :-)

One final tip: If you look inside the “Show hidden icons” pane in the Windows taskbar, you will see the Wireless Manager. If you right click it and select “Hide to notification area” it will then remove the app from the task bar. Even better is if you then go into the “Customize” menu and change the behaviour to “Show icon and notifications” you will get this neat and handy icon for quick access to mobile broadband:

Anyway, let me know how you go, and if I missed anything in my instructions.

    Your solution realy worked well. I have bought my Laptop two months ago and have been on many sites claiming to have asolution. When I got to this site, I was already exhausted of paging and reading for hours solutions that never worked. Not to mention losing my data on downloading stuff that never worked. I have been twice but because of being lazy to read all over again; I then thought that I will never find any solution for the cardslot to work. My latest plan was to get another Laptop and just forget about this one but now I am very excited to see it connecting on its own. Thanks a million times you deserve an AWARD.

    With the LG X120 with windows 7 (32bit) I found that XP drivers works very well (with the wonderful solution of Ericsson Wirless Manager 5)
    those are the drivers:
    Ericsson F3507g Drivers, Version 5.0.1044.13
    It installs like a charm, and works with no prob at all.
    the package also includes 64bit drivers.

    Great job. Thank you.
    Under win7 wwan is not supported with cisco vpn (ndis driver problem).
    You have to use dial up with win7 and cisco vpn or ssl vpn.

    God Bless You, Jack Ukleja!

    It takes me a number of days, trying to succeed with the driver from the LENOVO support page. Although I could see the Ericsson F3507g Mobile Broadband card on the screen it did not function on Windows 7 whatever I tried.
    Fortunately I found your web page….now, finally it works!
    The community needs people like you!
    Have a long and felicitously life!

    Sorry, does not work, because Sony does not recognise the F3507g Broadband Modem. One rason could be that I have a ThinkPad SL500 with Windows7 Ulitmate!???

    Hey @DougA, there’s no modded Zender BIOS for the T410. Did update to a stock BIOS version? Which one? Or did you get a modded BIOS from some one else?

    Lenovo never again, theyre definitely losing out. Whitelisting & other dumb moves.

    respected Jack,

    so very joyful ride throughout your articles on ericsson f3507g wwan and ways to get it in function for t400 series.
    Before I start writing more to you about various agendas, could you please tell me a few words on chances to workout your F3507g driver//application ideas and findings but related to thinkpad t430 lenovo.
    I’m helping a friend far from me, so I do not have wwan card, nor T430, but I understand your story and trying to solve my friend’s wwan f3507g ericsson into thinkpad T430 issue, blindly without hardware at my hands,

    I can also confirm this works for Windows 10 on Lenovo X200, with the same WAN adapter, f3507g. In fact, I’m posting this message via my WAN connection right now! The Sony-Ericsson Wireless Manager application was very tough to find, but this link still works (registration required – I use mailinator :) and be careful of the adverts which will try to get you to install all manner of crapware)

    As regards installing the Wireless Manager on Windows 10, rather than running the .msi installer as mentioned in Jack’s instructions above, I found I had to use setup.exe (in the same folder) instead… set the compatibility to Windows 7, run as admin, that did the trick for me. For the first time since I had this machine my mobile broadband works! and it works well!

    Computer: Lenovo X200 Tablet
    OS: Windows 10 build 10240
