3g

I just acquired a new Vodafone Mobile Broadband modem to replace an aging ExpressCard version I had that wasn’t working too well. It came in the form of a Vodafone-branded Huawei K4505 USB stick. It didn’t work completely out-of-the-box with Ubuntu 10.04, at first appearing unrecognisable. After some hunting, I discovered that these sticks initially present themselves as USB Mass Storage to allow you to install the Windows drivers. You have to give a few magic incantations on Linux to make them switch into modem mode:

As I’ve written about before, I use a combination of Vodafone 3G and the AT&T Network Client on Windows to access my corporate VPN. Recently, I’ve been seeing this error a lot when ‘dialling’ the 3G network (I connect it via the Windows dialler, rather than the Vodafone client):  This morning, I figured out what it was that was causing the problem. AT&T was open when I was dialling, and had the modem selected in the ‘Cellular’ tab (which I don’t normally use):

I’ve written before about how poor the Vodafone 3G Mobile Connect client is, and the alternative in Windows. However, it’s also worth mentioning that the card itself is far from perfect. It is very sensitive to the position of the SIM Card - having it off by even a few millimetres can mean it doesn’t connect, and it’s not always obvious what is wrong. The crucial thing is to have it poking out of the top, but only by half a millimetre or so.

If you’re anything like me, you _hate _the Vodafone Mobile Connect client - it’s buggy, unstable, and requires frequent reboots/restarts/taking-the-card-out-and-putting-it-back-in-again to make it work. What I only discovered today - although I should have known from ancient dial-up modem connections years ago - was that you can just use the regular ‘Network Connections’ facility of Windows. Just locate the ‘Vodafone Mobile Connect’ entry, right-click and select ‘Connect’ (I think this will only appear once you’ve installed the Vodafone software):
