Thanks,
I just checked. My serials start with 79IE so it was manufactured in september 2007. I also measured R17 and it is 63 +/- 2 which should be OK, right?
Wl noise gives -87 at first and -86 at a second try.
So do I definately have a good WL-500gP.
Anyone in Germany interested a spare BCM94318MPG REV4?
