I am running an up-to-date Ubuntu 13.04, and seeing this problem on my
Lenovo T430s. Many of my coworkers have this same laptop, and we are all
experiencing serious problems.
The card:
03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)
Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN
You can see the excessive retries bit here:
wlan0 IEEE 802.11abgn ESSID:"NI"

Bit Rate=65 Mb/s Tx-Power=15 dBm

Tx excessive retries:2432 Invalid misc:96 Missed beacon:0
Kernel:
Linux 3.8.0-27-generic #40-Ubuntu SMP Tue Jul 9 00:17:05 UTC
2013 x86_64 x86_64 x86_64 GNU/Linux
Disappointing that this has been a bug for ~2 years - it's fairly serious.
