Microsoft has a two tier logo program - there are a few wireless
routers that are certified to work with Vista. I'm using a D-Link
DIR 655 which is certified.
Other routers may work just fine. The various manufacturer's web
pages should have indications if a router has passed logo testing.
I've also got a D-Link DGL-4300 wireless router that works just fine
with Vista and everything else (but it isn't logo'd).
There will be more info from MS on how you can test a router
yourself to see if there are potential issues in the near future.
