OK, the Windows driver is better than the Linux one. Unfortunately, source is
not available.

You can check what we did when the RTL8187B was implemented. To do that, you
need to download the Realtek vendor-written Linux driver and check what they do
against what is in the current in-kernel driver. The critical areas will likely
be associated with power settings for the radio. Be aware that their code is
quite difficult to read as it has multiple conditional compilations that are
hard to keep straight.

I will be happy to test any improvements that you suggest.

Unsurprisingly, I imagine that the windows environment was what the
manufacturer had in mind. I mean no disrespect to anyone regarding these
tests. They simply serve to rule out hardware failures and mean that I can
help in my probably small and naive way to improve the driver.

Okay, I shall see how I go. I doubt my ability to come up with something
awe inspiring but if I can help and contribute then I shall make it a
