I'm very glad you did post this update as here in the office we had this very problem three weeks ago. One morning every non-Windows host in our building suddenly could not see past the gateway, could not ping it and was essentially off-air. We eventually tracked it down to one of these Belkin wireless routers, but never figured out why it was doing what it did. Now we do know, so thanks for the heads-up! alan -- gentoo-user@gentoo.org mailing list
