Sorry but I have only just come back to this discussion.

It is clear there is no signal from this output, and also from

The last line also shows there is no signal.

A couple of things to try:
1) Do ifdown wlan0 followed by ifup wlan0
Does this bring it back?

2) You are using the rt61 driver - you could try
modprobe -rv rt61
modprobe -av rt61
then
ifdown wlan0
ifup wlan0

This just unloads the kernel module and reloads it, and then restarts
the wireless.

You could also try 
service network restart

You might also post the contents of the ifcfg-wlan0 file... all this will
help diagnose what it going on.

Also before doing any of the above try seeing if the rt61 module is 
actually loaded by doing
lsmod |grep rt61
 and posting the output.
