Mobile broadband ok in Mint 16 but not in Mint 17

[adf2000]

Hello, I use a USB dongle to connect to the internet through a mobile broadband connection. In Linux Mint 16 Petra everything is working fine, but in Linux Mint 17 Qiana, while the connection is reported active, Firefox doesn't load any webpage and the ping command fails too. What should I do? Thank you a lot.

Post back (copy/paste) the output of these two commands in Terminal and let's see what you have going on there. (you can just copy/paste these commands too)

Code: Select all

inxi -n
sudo /usr/lib/linuxmint/mintWifi/mintWifi.py

Missing or misconfigured DNS-settings. Run command nm-tool and tell the DNS-settings.

I just run Mint 17 now and the connection is unexpectedly working. Thank you anyway.

Actually the story is a bit different. I found that both when I run Mint 17 via USB (live image) and when I run it installed from the hard drive, Firefox started browsing regularly only after I executed "inxi" and "mintWifi.py". I hope I won't have to do this every time...? I'll found it out on the next reboot. Thank you.

I think you misinterpreted what I meant a little bit, but that's ok. I wanted you to post back here what was shown when you ran those commands.

So we could, you know, maybe look at it and start to help figure out what might be wrong.

No, I got it right, but I thought it was not useful anymore. But I've just seen that after a reboot the behaviour is the same: Firefox starts browsing only after the two commands (I didn't tested if after inix or after mintWifi.py). Here's the output:

My mistake, sorry. You mean it works after you run the nm-tool command or the two you just gave the output back for? The "inxi" and the "mintWifi" commands?

So it works ok now as long as you do "whichever" it was after bootup? If that's good enough for you I can live with that. (if I get your meaning right this time).

[adf2000]

You mean it works after you run

I turned off the pc now and it's the same: Firefox starts browsing only after "sudo ... mintWifi.py". Rather boring to do that every time, also considering that in Mint 16 everything worked fine... Any suggestion? Thank you.

Hi,

as long as you run in a live session this will happen, at each reboot the settings are back to default and the system has to rediscover your network.

?????????

This is not you case at all is it? You have LM 17 installed on your system, right? A live boot session sure shouldn't do this anyway if it starts up with a working driver installed. Please confirm so we can eliminate the non-sequitur. Yeah, you shouldn't have to do "mintWifi" every time you start up.

Let us know, we'll try and debug it. It sounds a little like network manager is not starting on boot-up or something similar.

if it is installed then try to disable your wifi (seems not connected anyway) so firefox will use the broadband connection by default or change the network settings for firefox (firefox preferences advanced network and proxy to be set to auto detect).

[adf2000]

You have LM 17 installed on your system, right?

Yes, I'm using the installed version now.

if it is installed then try to disable your wifi [...] or change the network settings for firefox

Done, nothing changed. Again, both Firefox and ping command start working after I run mintWifi.py...

strange but not impossible, broadband has a higher ping and dns resolution process then dsl or adsl.

Could you please use this? open terminal and copy paste this:

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && \chmod +x wireless_script && \./wireless_script

It will download a script and create a file named wireless-info.txt or wireless-info.tar.gz in your home folder with wireless information so we can see the condition of your wireless or broadband at the time. The MAC address, WPA key and WEP key are removed for your security. Paste contents of the wireless-info.txt or wireless-info.tar.gz file at http://pastebin.ubuntu.com or alternatively http://pastebin.com/ then post the link here in your question.

everything looks fine (wifi disabled, wwan enabled and connected)

only thing left to check are
1) make sure it is enabled at start (default is to manually enable it as not all providers have flat fees)

2) run namebench (package manager) to check that the best DNS are used.

I can't, since my connection is not of the flat-fee kind.

2) run namebench (package manager) to check that the best DNS are used.

I'll try, but I can't understand why on Mint 16 I have no problems. Maybe I should downgrade...

[gtsfer]

Be patient with Pat's instructions and let him try to sort you out. If you downgrade you'd have to go LM13 as 16 is no longer supported. EOL means no more updates and can't install new packages, the repositories are off line (at least some of them are).

let's look at driver level and what this stick really is:
