Sure When you have broadband working with its proper dns and browsing works, do save the dns for broadband connection do a $ sudo cp /etc/resolv.conf /etc/resolv.conf.broadband for the broadband connection and when you are successfully browsing with dialup connection do the same but $ sudo cp /etc/resolv.conf /etc/resolv.conf.dialup When you are going to connect with broadband do $ sudo cp /etc/resolv.conf.broadband /etc/resolv.conf and when you will use dialup $ sudo cp /etc/resolv.conf.dialup /etc/resolv.conf This way you won't have to type it every time. > Thanks a lot again.
