Usually the device name will be /dev/ttyUSB0 (for a tata photon plus device I used). If it works then make a script and run it as needed. It may be a problem of network manager. If it works with wvdial then report the issue to network manager guys and they will fix it. If wvdial did not work: Try with different plans available in the list (instead of the correct one). This may work if your device switches to a different technology. Your net connection may work. But it may cause some trouble like higher billing rate so use it for some 4 hours and check the bill amount in net to make sure you are not billed higher. If you are billed properly then yeah this is the solution. But to my knowledge they won't change to a different technology. _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
