[bantybanty]

Dear All,

Anybody have idea how to setup Tata wimax 2.0 in Ubuntu 10.04?
I am stuck with this topic From 36 Hours. Actually Ubuntu is trying to connect but after some time its says wired - Disconnected. Seems network card is installed properly. But its working fine on my lappy windows xp sp3....
NVIDIA nForce network controller.
It's a Fresh Installed Linux.
There is No Router.... tata Wimax CPE(mounted on roof) to PoE to motherbord
I Know that TATA broad band uses DHCP...but its not resiving the ip automatically....

I think the DHCP setting need to be applied in Linux (Ubuntu 9.4). But I dont know how to do that Please Guide me Step by step i am new to Linux.. Anybody for help?

Thanks,
