i also have a wireless modem from huawei. this modem was built up from smartfren EC1260-2.
when i use windows, i have to install first the driver. the first time i use oneiric ocelot on my netbook, it's quite strange, because i did not familiar with the dock. i also happy when i plug my wireless modem with smartfren card. in the top right, i found connection drop down, and the modem was detected. i just need to edit connection, put username and password from the provider and i can automatically connect to the internet.
oneiric ocelot was fun.
