I have a TP-LINK WN7200ND, I am tested it with Kernel 2.6.36.1 and 2.6.35.10, basically after inserting the USB, the interface is up and it can never associate with any access point.
#lsmod |grep rt2
rt2800usb 7632 0
rt2800lib 20328 1 rt2800usb
rt2x00usb 4628 2 rt2800usb,rt2800lib
rt2x00lib 15408 2 rt2800lib,rt2x00usb
mac80211 122068 2 rt2x00usb,rt2x00lib
cfg80211 92252 2 rt2x00lib,mac80211
There are a lot of similar complaints on the net, this is one example :-
http://ubuntuforums.org/showthread.php?t=1530095
There don't seem to be any issue with 'iwlist wlanX scan'. But just can't associate.
Any recommendation ? Any debug information I should provide ?
Regards

Are your networks encrypted? How? What is output of wpa_supplicant? Did you try
nohwcrypt=1
?

Thanks for the reply. Now I am suspecting that it's the power supply to the usb device. The device is supposed to be 500mW, what do I have to do to check indeed the notebook usb power supply is not enough ?
Regards.

Good luck with you. My rt3090 also not work on 64 bit ubuntu but work
on 32 bit ubuntu.
You use Ubuntu is it? Which version? 32-bit or 64-bit version?
And, can you access internet through wired connection?

I am not using it on a 64 bit system. I have found out that for my case, it is not totally cannot associate. It's able to associate, but it breaks quite easily and it has great difficulty in establishing the association.
I am pretty sure it's a different problem from the 64bit thingie.
My notebook does have a built-in intel board using iwlagn. It is able to associate even when the network-manager is showing 2 bars of signal. Whereas using using wn7200nd, the network-manager is showing FULL 4 bars of signal, yet it has great difficulty in establishing association and after association, it breaks away from that easily.
I will try to loan a powered usb hub to see it makes any difference.
Regards.
