If you are trying to get a Huawei E169G modem from 3 to work on your EEE then please have a look at this blog post: http://www.greenhughes.com/content/huawei-e169g-easy-way

I've just been helping a friend get her Asus EEE PC working with 3 mobile broadband, which is a service here in the UK that brings a broadband connection to your computer over the 3G mobile phone network rather than using a wired telephone line. Many mobile operators have started offering such a service and it is a great option for people who live in accomodation that does not have a fixed telehone line installed or available, it is also quicker to get up and running than having to wait for ADSL broadband to be provisioned.
