Windows 7: Network lan and wireless is not working

we have bought Sony VAIO laptop model VPCSB18GG and using WINDOWS 7 PRO 64 bit. I am facing an issue. When i go home i will hibernate my computer. Next day morning when i switch on my computer from hibernate my network LAN connection and Wireless adapter will not work. Then i have to restart my computer again then LAN and Wireless will work. This i am facing only in this model. Please any one can give solutions for the same issue. What went wrong my hardware drivers or some thing else.

See if this gets your laptop reconnected.

Open Control Panel/Device Manager, click the arrow next to Network Adapters, double click the wired network card(not the WiFi card), click the Driver tab, click Disable, click OK, go back to the Driver tab, click Enable, and click OK.

hi thanks i have same problem windows 7 home premium i have this problem about 2months until now how sad?

When i check the network adapter it was in disable mode. When i try to enable nothing happens. So every time i have to restart the computer then it automatically picks the LAN and Wireless. Please let me know if any solutions for the same.
