Huawei E180 Wireless Modem in Ubuntu Karmic

I have an Acer Aspire 4736Z running Ubuntu 9.10 dual boot with Windows XP (for work). Ubuntu recongnizes the modem but it won't connect. I've searched the Linux forums for help but most are too technical for me. I've been using Ubuntu for about 3 years now, but haven't really gotten into scripting and making changes to configuration files. The help I've seen has been pretty easy to follow but I still can't get things to work. Anyone out there that can guide me? Thanks.
