|I having also a similar problem where in the default gateway is blank and The subnet mask has the same addrerss 255.255.0.0. |
It was working fine but i did some install of Wirlesss connection and since then it dosent connect to the Net any more.
When i use the same cable modem connectivity on another lap top all works fine so some thing has gone with the network settings.
We are sailing in the same boat :-)
