Description of problem:
the
When I upload in my lan big files (>200Mb) upload starts, with a 700k/s up to 1mb/s rate for a few seconds, sometimes even half a minute, and th
en dies (load drops to 0 and even though wlan0 is up, routes are lost).

Using atheros chip on a Dell Inspiron M5030.

Perhaps you could try update the kernel, eventually try compat-wireless-next packages from http://people.redhat.com/sgruszka/compact_wireless.html (or installed from tgz source). If that not help try to report bug to ath9k developers according to
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob_plain;f=MAINTAINERS;hb=HEAD
