ComicChick,
As you know, since I messed with the Beta and RC, your router will be down right fine, IMO. It has better wireless controls all the way. =) Can do everything from the taskbar, which is fantastic! Should have been this way on Vista too, well, lot more cleaner anyways.
In the end what matter is the Wireless (Card) Drivers, and not the router. I have a 6 to 7 year router (Oh, how I love Linksys WRTG Series on on DD WRT). But as I've said, if your driver isn't out yet you can use Vista's, but might have a few hiccups but it will work if comes down to that.
