Continuing from "How to successfully restart a network without reboot?"

Hello Jorge Castro

Thank you for your detailed response on the topic [how-to-successfully-restart-a-network-without-reboot]. The discussion there seems to come closest to addressing my problem. (I'm beginning a new question because I don't have enough Reputation points to continue the earlier discussion with a "Comment")

PROBLEM: Although my situation is a little different, I would like to ask if you can help.
Rather than a wired or a wireless network going down, I am using a USB modem (ZTE - MBlaze) in India.
Each time it disconnects, the ONLY way that I can get it to reconnect (at least 80% of the time) is a complete RESTART.

SOLUTIONS TRIED: I tried both the suggestions in this strand, and in the link which you provided.
"sudo service network-manager restart" as well as "sudo ifdown -a" / "sudo ifup -a"
NEITHER WORKED - Only a complete restart will allow use of the modem

OTHER POSSIBILITIES: I can try a "reboot without actually shutting down" and/or "kexec" but it seems that for both of these I would have to close all applications. They will only reduce the time, but not eliminate the inconvenience of a reboot.

QUESTION: Can you suggest other Terminal commands that could help?

Thank you!

Bryan

With some perseverance, the solutions suggested by Jorge in his earlier post How to successfully restart a network without reboot? solved my problem.
Using 'sudo service network-manager restart' followed by 'sudo ifdown -a' and then 'sudo ifup -a' works on my Ubuntu 12.04 netbook.
It always takes time. Once the network has restarted, it may take several minutes to "rediscover" my USB modem.
Sometimes I have to repeat the process.
Still, reconnect this way is FAR better than closing all programs and restarting Ubuntu every time the internet link drops.
