I use a MacBook Pro running 10.4.11, and at home we use a modem (adsl)
and and a Netgear WPN824 wireless router. Everything works just fine.
Then I bought my family a MacBook for christmas. (This shipped with
Leopard installed.)

The problem is that the Netgear wireless router hangs whenever you play
web-based flash videos (i.e. YouTube) from the new MacBook. A video
will buffer ok for about 10 seconds then the router hangs and needs to
be restarted. Apart from this specific issue there are no other
problems.

I have searched everywhere but haven't found anything relating this on
the net (there are similar Flash/YouTube issues which seem to be audio
related but that is not the problem here). I have done what I can to
locate/solve the issue (repaired permissions, installed the latest
Adobe Flash player, tried different browsers etc.) but nothing helps.
And there is really no way of knowing where the problem is except that
it must be related to the router and/or Airport (as the problem isn't
there with a wired connection). And using the same reasoning, it can't
really be a Flash or Leopard issue either. But on the other hand the
issue only affects the new MacBook, and the only real difference
between this and the MBP is Leopard...
But the router seems to be most likely culprit.

I would be most grateful if anyone can shed some light on this!
