wireless disconnects after a couple of minutes

[Invisiblekid]

well it happens since backtrack 4 actually, same as in another thread of the forum.
i didnt find any useful answer for this one and i just dunno what to do...

i have created a short video showing the whole thing and uploaded it


i am using a usb dongle called levelone wua-0605 which is working on a realtek chipset...
on my windows drivers folder the driver is "RTL8192su", on the vmware it says "RTL8191S", and on the backtrack the name is shown in the video (from airmon-ng).
other then that... most of the info is on the vid, and anything else you need just tell me ill try to respond quickly.

my router is a netgear DGN2200 and i am using a WPA encryption.
i dont really see anything that could block backtrack from the router like an access list or something i dunno...
if there are any other names for something that could block please tell me.

i am running the VMware image of backtrack 5(GNOME 32 bit) on VMware workstation.

and if you think the dongle is just not supported or something please say i am thinking of buying another cuz of this but i dunno if thats the problem.

tell me if you need any other info and sorry for my english and the long boring post

thanks a lot for any info you can help me with, much appreciated ...

try this:

iwconfig interface power off

(replace interface with your network adapter, for example wlan0 or wifi0 or whatever0)
you probably have power management turned on

[Invisiblekid]

i get

Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not permitted.

i am root so its not that.
in the video you can actually see that if i do an iwconfig, it says power management off anyways.
notice that its seems more like a driver problem, but i am not experienced enough in linux and dunno how to install drivers.

thanks a lot for your comment btw.
