[rt2x00-users] rt2800usb stops at random

[岡野 拓生]

Hi,

I have a WG-G300U(Railnk rt3070) usb dongle.
It is used by hostapd on ubuntu11.04 of beagleboad-xm.

However, it may not be connectable although SSID can be found. 
It often occurs that can't connect to hostapd's AP although SSID can be found. 

I attempted to change it into a different machine,ubunt12.04 on x86-pc .
But,it happens. 
I checked a driver, it seems that RX/TX Handler is not operating. 

When this phenomenon occurs, the following procedures may cure. 

/etc/init.d/hostapd stop
ifup wlan0
/etc/init.d/hostapd start

Although timing and Locke feel me dubiously, I cannot specify somewhere.
