I've implemented your suggestion and the Network Manager was unable to detect any wireless networks at all. I posted results here: http://pastebin.com/m5a2f0b96.
Oddly enough, I re-enabled encryption on my router and my Network Manager was able to, once again, discover all available wireless networks but I still can't connect to the internet wirelessly. What's next?
You could try bringing, as root, the wlan0 interface down and then up:
# ifdown wlan0
# ifup wlan0
# iwconfig wlan0
# iwlist wlan0 scan
# ifconfig -a
NB the first command may fail - don't worry about it - it just clears the ifstate
the second command brings it up, the third command should show the essid (access point name) you are connected to, the fourth scans for all aps within range, and the fifth shows what IP address your wlan0 interface is linked to and whether it is transmitting and receiving.
Your pastebin dump shows that the scan worked fine with encryption off.

In your post - all of them is wireless. What do you mean?
nimnull22 - I ahd to think about your post for a while .... but M's post says that his network manager (god bless them all) doesn't see anything whilst we see a sucessful scan and know that the wlan0 interface is up and working but not connected/connecting to the Nexus access point.
So when he gets back to us, I intend to give him some manual iwconfig settings to lock his machine into the Nexus ap, like you I don't use network managers! That's probably why we keep meeting like this ( I know you come here often - so I won't ask! ).
the iwconfig eth2 output shows that you are connected to the right access point 00:22:57:1F:E9:CF which is the Nexus MAC address see your scan output Cell2.
However you have put encryption back 'on' on the nexus router and we haven't got there yet.
If you reset the encryption to open, then try in a browser to open http://192.168.1.1 you should wirelessly connect to the router admin / password page. we'll progress from there if you are successful. Incidentally, there is tons of traffic going through eth2 1.6MB received and 108.8KB transmitted according to the output of sudo ifconfig -a
I couldn't connect to http://192.168.1.1 from my machine so I had to use my windows desktop to disable Nexus' encryption protocols. Once completed, I tried to connect to http://192.168.1.1 from my laptop and was unable to do so. Tried to do it wired and wirelessly. Same result.
sudo route -n does not produce any output. Since disabling my router's encryption protocols I am unable to connect to Nexus. Oddly enough, the system requests my WPA2 password but I disabled that.
