D-link USB Wlan Adapter DWA 160A crashes after a while

[Adhari]

Hello Everybody

I´m usind a D-link USB Wlan Adapter DWA 160A (ar9170usb) under Debian (kernel 2.6.31)

First when I connect this device, everything is fine. I have to do some measurements concerning Mipv6 (I´m only using Ipv6 here)
after a while using this W-lan Adapter (30 to 60mn) the system is not be able to receive any packets.


The only solution is to plug the USB interface out and to connect it again.
ifconfig down and up has no effect and sometimes rebooting either don´t correct this.

Any idea what the problem could be?

Is this some sort of trick question? Because you gave
the correct answer already in the "Subject" line?!

my suggestion:

1. get & compile compat-wireless (this will give you
	an updated ar9170usb.ko driver. http://linuxwireless.org/en/users/Download )

2. replace the old two-stage firmware files with one-stage ar9170.fw
   (link: http://wireless.kernel.org/en/users/Drivers/ar9170 )
