A couple of questions.
Does this still happen with the non-beta version of Ubuntu?
If so, can you connect manually, via the wifi icon on the top bar?

Title:
Wireless authentication fails on wake in Ubuntu 13.04
Status in “gnome-power-manager” package in Ubuntu:
Incomplete
Bug description:
I have upgraded from Ubuntu 12.04 to Ubuntu 13.04 beta x64. Now, I can see
that whenever I put the computer to sleep by closing the lid, the laptop fails
to connect to the previously connected wifi network on waking up.
I have to do a complete restart for the authentication to work.
Using the hardware switch to turn off/on the wireless or restarting
wireless services do not seem to have any effect.
The laptop is a Dell Vostro 3300. Details of the wireless card
lspci | grep Broadcom
12:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless

I am also attaching the syslog for the timeframe in which it happened
