I am using a Asus laptop with Ubuntu 12.04.
My internal wifi adapter stopped working. So I put in a usb adapter. But then I had two adapters both trying to connect to the same network, from Which neither can connect. They keep knocking each other offline.
So after doing some research I was went into
etc/network/interfaces and changed it. So that
wlan0 was manual start instead of auto start. At that point I tried to reboot, and at the splash screen I got a message that the computer was waiting network connection. After a minute or two, that changes to continue booting without correct network configuration. And that's it, it just sits there, doing nothing.
So I boot up with my live CD, and used
gksudo nautilus, and went back into the Operating system filesystem (not the filesystem on the cd), and corrected the changes made in the interfaces file,then reboot. Still the same.
continue booting without correct network configuration, error msg. I have went back and verified the corrections I made were accurate against the CD filesystem.
So what is happening ?
How did I mess up that bad by just adding
iface wlan0 inet manual( from those instructions I found here ) ?
I decided that was easier than blacklisting, because well it just seemed easier. Just my luck.
Here are the results of some terminal commands, I got these from booting onto the Live CD. I've also had two adapters plugged in together with no problem, but it kept saying wlan0 connected , wlan1 disconnected etc. Until I either get this fixed, or reinstall for all practical purposes it is bricked.
I do have the FN+F2 combination, I didn't do that to start with because that also turns off the USB adapter . After turning wifi off, and rebooting still the same thing, here's the results leaving off the Wired ethernet other than just to mention it. Also you will notice that the wireless adapters are both the same brand, which is unusual.
