I recently updated to 13.10 from 13.04. After rebooting, the system dropped into low graphics mode. I had previously configured a Wireless Broadband connection named:"EVDO Connection". How do I connect to this network from terminal?

[note] I tried using LiveCD and then the chroot command but then I was unable to make apt-get install any updates. It did not detect the internet connection.

Additional question, I read somewhere that

sudo apt-get update && sudo apt-get upgrade

will resolve the low graphics issue. Is that correct?

It is preferred if you can post separate questions instead of combining your questions into one. That way, it helps the people answering your question and also others hunting for atleast one of your questions. Thanks! – guntbert Oct 20 '13 at 20:11

Ubuntu's NetworkManager service can be accessed via a command called nmcli. I'm not too sure if it's installed by default, but it seems it is, since it's part of the network-manager package.

To connect to a network, you need to know its NetworkManager ID. You can do so by using the following command:

nmcli connection

This should give you a list similar to this:

yjwong@yjwong-laptop:~/Documents/searchagram/build$ nmcli connection
NAME       UUID                                   TYPE              TIMESTAMP-REAL

To bring up the "Wong" connection, simply execute:

nmcli connection up Wong

If your connection was named "EVDO Connection" you can execute:

nmcli connection up "EVDO Connection"

I'm sorry for this delayed a response, but thanks. Your answer worked fine for me. – aero31aero Nov 29 '15 at 5:42

You can use the following command for wireless devices:

iwconfig wlan0 essid NETWORK_NAME key WIRELESS_KEY

replacing the capital letters with the actual network and key

see the complete guide on

the commands you mention (update & upgrade) will update your system and additional software to the latest version, it may or not solve issues you are experiencing.
