I'm having same problem with Acer Aspire V3-571 and Linux Mint 13 Maya. I also saw that restarting from the sleep causes dificulties to reconnect the network, in that case rebooting is best way to get ride of the problem :(
Here system info:
uname -a
Linux aspire 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
lspci | grep Network
03:00.0 Network controller: Atheros Communications Inc. AR9462 Wireless Network Adapter (rev 01)
