ethernet

I upgraded from Ubuntu 11.10 to 12.04 yesterday. I am running a BSNL Broadband DSL conenction. The wired network suddenly dissapears and the computer stops detecting the ethernet card after sometime. However, after rebooting, it again becomes alright.
Specs :
Lenovo Ideapad Z570
Intel i5 2nd Gen. processor
3 GB RAM

$ lspci | grep Ethernet 
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
