    WIFI drops every 1800s - DHCP lease

      I found out that my edison is dropping the wifi connection every 1800 seconds showing the following message:

      9080s - 7266s = 1814s which seems to be exactly the dhcp lease time. It is independent if I use Yocto or Ubilinux?

       

      Why does my edison disconnect every 30 minutes? Could someone help me?
