I hav been using ubuntu 10.04 LTS for the last 5 months... used tata photon plus for networking ...everything went fine when couple of days ago, after doing normal updates as listed by the update manager, sound went off.. to solve this, i had to remove and reinstall certain packages as listed in http://ubuntuforums.org/showthread.p...+documentation, i had to restart, after restarting, the sound problem was gone but the network manager icon went off, the modem was not getting power from the computer though the LAN wire was connected. To add to dismay, the mobile broadband connections that i had added to the network manager were gone. I tried adding the tata photon plus (huwaein) again but could not be added, reinstalled usb-mode switch data and related packages, but still the computer doesnot detect the photon as usb device...

I have broadband dsl connection and tata photon plus too but cant use any of them.

PLZ HELP.

I moved your post to its own thread. Please don't hijack another thread. It makes it too hard to help the original poster when unrelated posts are mixed in.

jschiwal: sorry for posting into the wrong thread. Thanks for the move here.

If one of your updated updated the kernel, you may need to modprobe a kernel device so you hardware is detected. Look at the "lsusb" command for usb devices and "lspci" for other devices. For lspci run "lspci -v" and "lspci -n". The latter version will provide the manufacturers ID which might help determine the kernel module needed.

Also provide your kernel version: "uname -r".
