I know that this issue might have occurred quite a few times with other users, and I tried to search for it, but all I found was users whose internet was not working even with other distros.
Wireless modem is not detected in Linux Mint 13 and Ubuntu 12.04, however, it works fine with LMDE, Ubuntu 11.10, Mint 11 etc.
I tried even installing Ubuntu 12.04, and Mint 13, but of no use. The modem does not work either in live-cd mode and after actual installation. However, it is detected and I'm able to connect to internet even in live mode when using LMDE, Mint 11 (I haven't tried it with Mint 12) and Ubuntu 11.10.
Partial lsusb output:
When working(LMDE, Ubuntu 11.10):
Bus 002 Device 004: ID 12d1:140b Huawei Technologies Co., Ltd. EC1260 Wireless Data Modem HSD USB Card
When not working(Mint 13, Ubuntu 12.04):
Bus 003 Device 003: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800 (HSPA modem)
Thus, in LTS distros (Mint 13, Ubuntu 12.04), modem is not detected as data card, but simply as a modem, and hence, I'm not able to set up network via network manager.
Currently, I'm using LMDE,and this issue occurred there too. Modem used to get detected as simply HSPA modem (instead of data card), but the issue used to get fixed when unplugging and re-plugging the modem. However, the issue went away completely when I updated to LMDE SP4.
I'm quite disappointed to see why these 'LST' distros have this issue (i.e. modem not working out of box). I was planning to ditch LMDE for Mint 13 (one reason is because updates on LMDE are quite slow), but this is the only problem which is holding me back.
Any suggestions to make it working would be helpful.
