Both during and after installation, 13.04 doesn't support the Broadcom-based 802.11ac wifi chipsets. lspci reports it as "Network controller: Broadcom Corporation Device 43b1 (rev 03)".
WORKAROUND: 6_30_223_95 driver in http://people.canonical.com/~ypwong/drivers/broadcom/ , install an old version: https://launchpad.net/ubuntu/saucy/amd64/bcmwl-kernel-source/6.30.223.30+bdcom-0ubuntu3 (found at http://gaspuu.blogspot.no/2014/05/dell-precision-m4800-with-ubuntu-linux.html), or simply replace the wifi module with another one with better driver support (if laptop has no whitelist for modules).
