I have a Netgear WG111v3 (RTL8187B) card. I have the same problems.

I have also tried the following with no real gains:
1. Ubuntu 9.10 with all kernel upgrades
2. Ubuntu 10.04 with all kernel upgrades (2.6.32-22-generic) and with 2.6.34 kernel from Ubuntu kernel mainline (http://kernel.ubuntu.com/~kernel-ppa/mainline/)
3. Backtrack 4 cd

If I use "iwconfig wlanX rate auto", then the rate for the interface hovers around 1M most of the time. On manually forcing a higher rate (i.e., above 24M) the connection automatically drops periodically.

Search for the term "No probe response" in the syslog.txt file attached. These are the time instances when the connection drops and reconnects.

The distance from the Laptop to the Router is less than 5 meters and there is line of sight. There is no obstacle (wooden partition or a wall) causing the signal to drop.

The card works fine with stable connection in Windows XP. Using ndiswrapper with windows xp inf+sys files in Ubuntu 10.04 (2.6.32-22) also works fine. But, the native drivers in the kernel do not work properly.

I can run some additional tests or traces to provide more insight into what might be going wrong with the driver.

I'll attach my iwconfig and lsusb files in the subsequent posts.
