I just installed Ubuntu 10.04 LTS.
However, my D-Link DWM-152 (HSDPA USB modem) is not able to be detected.
I am having exactly same result as c_siswan http://ubuntuforums.org/showthread.php?t=1476983
Can anyone suggest me a solution?
Go to www.dlink.com, support+download and then search for DWM-152 and update your firmware. Have a look at this Blogpost saylinux.wordpress.com/2010/07/20/using-d-link-3g-usb-dwm-152-with-ubuntu-10-04/
Maybe it works with network-manager if you try the newest developer version from here: https://launchpad.net/~network-manager/+archive/trunk
Give sakis3g a try. If it works than we know the modem works on Ubuntu and it's just a matter of including it in usb_modeswitch data or toggling it manually and we can work towards that.
