Default Bug#626309: linux-image-2.6.38-2-amd64: Wifi connection drops randomly with Realtek RTL8187 wifi adapter

Package: linux-2.6
Version: 2.6.38-5
Severity: normal

I have a USB adapter (identified as Realtek RTL8187 Wireless Adapter) that I
use to connect to wifi. Until updating the kernel from 2.6.37-2 to the current
version, it worked perfectly, but now the connection drops randomly: sometimes
once a day, sometimes every 20 minutes, and sometimes all the time. The
computer can still detect the Wifi network, but I can't browse or download
anything. The same computer with the same adapter can connect perfectly with
Windows 7 and with the previous kernel, and the system does not detect any
signal drop when the connection drops, so I suppose it's some driver issue.
