I just opened a brand new Dell XPS 13 Ultrabook and connected to my 802.11n wireless network.

Performance is abysmal. Web pages time out, SpeedTest shows 0.15 Mbps (on a 50 Mbps FiOS connection), and the ping between my computer and the wireless router is between 700 and 3000 milliseconds.

Oddly, connection to a 802.11g network works flawlessly. What's wrong?

It turns out that upgrading the Intel Wireless driver (Centrino Advanced-N 6230) from version 15.1.0 to 15.2.0 fixes the problem.
