Intel Centrino Wireless-N 1000
There is a firmware bug that sometimes drops connections - also affects other Intel wireless chips but it may be linux specific.
Some discussion about it can be found on the linux kernel.org bugzilla
The bug is known by Intel and there is an experimental firmware available on their site. Unfortunately it needs a special linux kernel config to work. Just copying it to /lib/firmware is not enough. See their readme for details.
A quick temporary fix is reloading the module (modprobe -r iwlagn; modprobe iwlagn).
A more permanent workaround is disabling 11n with this iwlagn module parameter: 11n_disable=1. This should help even if you don't use 11n anyways. I use this 11n workaround for a short while now and had no connection drops since then --Joban 20:08, 29 November 2010 (UTC)
