Internet Issues with Ubuntu 12.10

view story

http://askubuntu.com – I have dual boot system with Windows 7 & Ubuntu 12.10. When I log in to Ubuntu - facing issues with accessing Internet. It is working fine for few mins and stops working. I am not getting any error messages to trouble shoot.. But I Could able to ping default gateway & DNS servers (When not working also).. But there is no issues with Windows 7 as far as accessing internet(so no issues with services provider). Could you please help me out with this,.. Thanks in advance Regards, Deena (HowTos)
