I'm not Ubuntu user but on Sabayon Linux, Thinkpad X201, Centrino 6300, kernel 3.10.0 I don't think this is fixed. Quite simply there are long pauses in network activity which makes interactive use a pain and downloads slow.

For example, some ping statistics of my base station just a few feet away:

30 packets transmitted, 18 received, 40% packet loss, time 29025ms
rtt min/avg/max/mdev = 3.105/14.805/195.911/43.949 ms

Average download speeds vary between 2-3 MB/s so not great. This with 100 Mbps downstream and the other end can saturate that easy if using ethernet reaching about 11MB/s. My ancient Toshiba Portege R500 also maxes that out with wireless...

Power saving on the wireless adapter don't seem to make much difference.
