Okay.... Here's another problem with a broadband modem.
I'm using Ubuntu 12.04 Precise...I was using a ZTE MF 180 modem which was working fine after i did some configuration..
Recently i got a Huawei E1550 from a friend and i plugged it in and made a new connection and everything was working well... but suddenly the modem network disconnected and i reconnect several times but it just won't connect..
I thought the prob was with the device so i revert back to my old modem which is ZTE.. But now that also gives the same error..
Wondering what i have done wrong here...Any help would be greatly appreciated..
