Storming is essentially a fixed association backoff that keeps the
driver from going into a tight loop trying to associate to a single AP,
failing, trying, failing, etc.  So it puts a 3s timeout between
association attempts to any one AP.

Age means you haven't received a beacon or probe response from that
network for > 25 seconds.

The 'AUTH_SEQ_1' notification means the authentication sequence during
association is failing, most likely due to a timeout in not receiving
the response from the AP.  Association fails.

What is the signal strength of the network when seen via 'iwlist scan'?

The above would indicate that the AP is likely providing a weak signal,
is under heavy load, or you have a saturated or RF noisy network that is
preventing consistent communication betweeen the AP and your client.

Are there other 802.11 networks on that channel?  Bluetooth devices in
use?  Does anyone use a 2.4Ghz wireless / cordless phone within 300 feet
of where you ware?   Wireless keyboard and/or mouse?
