Mac/linksys wireless issues?

[yendi]

Anyone happen to have any experience with older linksys wireless routers losing their connections and having to be reset when a newer ibook (with airport extreme and the more recent 802.11 implementation) connects to it? 'song's new iBook seems to cause our wireless to go out on a recurring basis (and it's the wireless itself, not her computer -- I lose my connection, too), and it doesn't come back on until the traditional tech fix (unplugging the router and plugging it back in). is applied.
