Can't connect to Internet(network). Why is route (default gateway) deleted when DHCPDISCOVER happens ?
Issue
I can not connect to Internet(network) when the following messages appear
Dec 21 12:33:37 HOST-A dhclient[1142]: DHCPREQUEST on eth0 to 192.168.1.1 port 67 (xid=0x25c2f67e)

When these messages happens, it seems that route (default gateway) is deleted so you can not connect the network.
