[Bug 544254] [NEW] iwlagn (i4965AGN) continually drops and reconnects to access point

[Christian Reis]

Public bug reported:

I use a WEP-protected AP that is about 1 meter from my Thinkpad X61.
Since upgrading to Lucid, I'm seeing this litter my syslog exactly every
2 minutes:

This very quick drop in connection isn't reflected in the NM applet, and
it doesn't cause IRC or web connections to fail; I just feel it in that
SSH very slightly lags while I am typing.
