I'm having severe issues w/ package-loss and a generally bad connection w/in a WiFi-network at my uni. I'm usually encountering a package loss of ~50% and aborting connections which makes working w/ SaaS impossible.
I'm using Ubuntu 13.04 and my network-adapter is an Atheros AR9462.
Applying the nohwcrypt=1-option doesn't change anything.
Also very noticable: The connection works as intended in other networks; the problematic network uses WPA2 w/ MSCHAPv2.
Anyone can help my out here?

nohwcrypt = 1
option that you are referring to is from this? Just to clarify, did you follow that exactly? (meaning you typedoptions ath9k nohwcrypt=1
in/etc/modprobe.d/ath9k.conf
modinfo ath9k
