Wired and wireless not working all of a sudden

Hi. I am unable to connect to wired nor wirelss Internet. This started today. I changed the router password using the desktop cpu, and when I tried changing the wireless password on the laptop, something happened (I don't know what) and now all the available networks are gone and the following is all that shows from the network icon:

<grayed out -->Networking Disabled
               Enable <u>N</u>etworking
<grayed out -->Connection Information
               Edit Connections
This is all I see whether I right click or left click on the network icon. Clicking them usually does nothing although sometimes when I click "Edit Connections" it will allow me to edit the connections to no avail.

Also, when I go to System Settings --> Network:
Clicking Wired give me nothing to modify and clicking wireless shows no Network Name except "Other..".

The wired connection does not work either.

One second all this was working and the next second nothing.

Ubuntu 12.10
Unknown driver
Intel Core i5-3317U CPU

# iwconfig
eth0      no wireless extensions

lo        no wireless extensions

wlan0     IEEE 802.11bgn  ESSID:off/any

          Power Management:on
# ifconfig
lo        Link encap:Local Loopback
          inet addr: Mask:
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:315680 (315.6 KB)  TX bytes:315680 (315.6 KB)
Other laptops connect fine and the Ethernet cable works fine on other devices.

Okay. Just so happens that right after I posted this thread, I click on "Enable Networking" again and all is fine now.

And this reply gets you off of the zero-reply list, nothing else. Good job fixing it!
