Thanks for the question, which, as it seems, is also an answer ... :)
My early computer lessons, IIRC, made me believe that 2 devices should
not share the same IRQ ... I wasn't sure, whether this is still valid:
Windows <whatever-version>, please see:
<http://www.buildorbuy.org/irqmap.html>
As I said: In this case, where the radiocard shares the irq with the
bridge it is connected to I thought it might not hurt. But I was not
sure on that ...
I'm trying to set up a little wifi-network, and it does not always
work as it should: With my questions I simply wanted to make sure the
IRQ "issue" actually isn't one, and that it is not the source of my
wifi troubles...
Thanks a lot for responding, Ben ..
Best Regards
Wolfgang
