Is anyone else seeing the same issue?

I have a Thinkpad T40p with the built-in wireless (It is Atheros chipset).
Using GenMAC 1.6 with XWLAN 2.14, it has been pretty much flawless.
(Warp 4.52 with FP5)

I tried GenMAC 1.7 a while ago, it was worse so I switched back. I
recently upgraded to GenMAC 2.0 with XWLAN 3.0 and it shows the same
behaviour. MUCH worse!


Here's the symptoms:
- The reception shows typically 5-10% weaker signal, for whatever
reason. (I'm in a small apartment, so it's easy to be repeatable to be
in the same physical location).
