[SOLVED] Maya Mate Internet becomes disabled

[y-man]

I did use internet both --wired and wIreless-- on this system in the past.
One day I wanted to add another wireless connection. I was not successful,
and since then I cannot use or set up any connection.

Here are the symptoms:

Right clicking on Network Connections icon on the panel, I got only "Edit
Connections" choice alive. Clicking that, then "Wireless" tab, then
"+Add" button I arrive a data entry window, but all its contents are
grayed out.

Selecting Main menu -> Administration -> Network, then gaining root
access, selecting "Wireless connection" then clicking "Properties"
button, I could enter, and then edit seemingly succesfully. But this
new connection is never activated, nor it becomes visible from Network
Connections icon on the panel.

The output of mintWifi.py:

============= end output

Any suggestion will be much appreciated. I did search this forum and
internet in general to no avail.

I hope I will get some help here and be saved from having to
reinstall.

Thanks in advance.

You can't use any internet on that system or just can't use wireless?
Try

Code: Select all

sudo aptitude reinstall network-manager

make sure /etc/network/interfaces has only two line

Code: Select all

auto lo
iface lo inet loopback

I am having a similar problem. I posted my original problem in the wrong category here: http://forums.linuxmint.com/viewtopic.php?f=90&t=123775

I have no internet access through my laptop because it is through my school so I have no ethernet to use.

When I ran the "sudo aptitude..." command, the final result said "E: Internal Error, No file name for network-manager."

i was unable to use any networking at all. I tried with just doing the mod to /etc/network/interfaces, that you suggested, and it was enough to get me connected (so far I tried only wireless).

Thanks a lot for advice.

Marked SOLVED.
