I think my problem is almost the same.
I boot and then I have internet connection for few seconds, then it disconnects and try forever connect on my network.

Yes, resolv.conf wasn't there, I used:

Code: Select all

sudo dpkg-reconfigure resolvconf
Rebooted, and the resolv.conf has nameserver 127.0.0.1 but nothing has changed.

I'll try two other possible solutions and edit this post with my results.

@edit
This:

Code: Select all

gksudo gedit /etc/NetworkManager/NetworkManager.conf
...etc... didn't work.
Nor this:

Code: Select all

sudo resolvconf -u
@add
I ran that mintWifi script:

Code: Select all

I just found out how to solve my problem.
I changed my Wireless router settings from WPA to WPA2 and everything just worked fine now.
Don't know why but it works

I followed this fix, but no success. Here are the results:

gnapps@gnapps ~ $ sudo gedit/etc/resolv.conf
[sudo] password for gnapps:
sudo: gedit/etc/resolv.conf: command not found
gnapps@gnapps ~ $ sudo gedit /etc/resolv.com

(gedit:2591): GLib-GIO-WARNING **: Missing callback called fullpath = /root/.local/share/recently-used.xbel

What's next? And in case I haven't mentioned, I appreciate everybody's input so far. Just a big learning adventure. When I sleep at night, I dream about this terminal as though I am stuck in the Matrix!

Hey,

I'm having the same problem.

I am using a Dell Adamo 13 with a -- Intel 5300 WLAN 802.11n (3x3) Mini Card

I can connect to my network just fine, but I can't connect to any websites unless I'm on a wired/ethernet connection.

I'm not super tech savvy, so if one of you figures out what's going on I would greatly appreciate the newb-speak version of the solution.

Thanks,
B

This could also be because your laptop is currently not plugged in with power supply and so the power management on mint screws up your wireless connection by disabling somethings.
The following thread http://forums.linuxmint.com/viewtopic.php?f=53&t=111658 pointed me to http://uselessuseofcat.com/?p=67 which solved the problem for me.

I had a similar problem. For some reason I can not guess, I lost my internet connectivity. Rebooting computer, router, etc, nothing worked for 2 days. Found this thread, tried some things, and the one that worked is "dpkg-reconfigure resolveconf"

I choose 'yes' for a few of the options that would allow dynamic updating of the config files.

The only thing I can say is that this is a complete mystery why this would happen. I've been running this version of Mint for almost 8months with no problems. Frustrating. I'm no noobie, been using linux for years. I haven't had this kind of network trouble since the 'win modem' days.

Thanks for the thread and the help.

Love the forums.
