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).
- It takes MUCH longer to acquire IP address, sometimes it fails to
ever acquire unless I ask to "scan for connection" again.
- Connection fails after some time. i.e. I can surf and connect to all
the web sites for about the first 10-15min.  or whatever, but then it
"dies". XWLAN shows green and connected, but I cannot even ping my own
router or any other web site.


Any tips or suggestions?
I've reverted back to 1.6 for now since the newer editions are
essentially unuseable for me.



Thanks,
Isaac
