This "bug" still persists after doing a clean install of 14.04 (coming from 13.10).

When I power on, sometimes I just see the WiFi icon animation, trying to connect but not succeeding. I do several power off (or restart) cycles before my netbook's WiFi detects and connects to my home network.

But if I do a suspend, I notice my machine connects right after resume.

lspci -nn | grep 0280 output:

05:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

iwconfig output:

lo        no wireless extensions.

eth1      no wireless extensions.

wlan1     IEEE 802.11abg  ESSID:"Like A Virgin"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: 58:6D:8F:CC:DC:F2   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

My machine is a Samsung NF310 netbook.

thanks to @terdon for guidance.

Please edit your question and telle us what your network card is (just run lspci -nn | grep 0280), what your computer is, include the output of iwconfig and also any error messages found when running dmesg.
