Unable to reach 192.168.1.1

am using a combo plan of mtnl.I am not able to connect to internet though my phone is working and modem lights are showing normal status.The window u get on rt clicking the internet connectivity icon on task bar shows 0 traffic.On clicking the support tab in the same window in the connection status all categories(ip add,subnet mask,default gateway) are shown blank hence the repair command cannot work.This cannot be corrected inspite of entering this data in tcp/ip settingsn from the contoll panel.
I also have a tata broadband connection which is working smoothly on the same machine.The local mtnl man is at loss and the officers are not accesible(? strike).
Any suggestions to solve the problem?
Can thre be a conflict because of the two NCDs? I always put the device not in use and the NCD not in use is disabled.
I cannot ping 192.168.1.1 (unreachable) though the modem is working as tested on other machine(Sterlite sam 300X)
Please suggest ways to solve the problem as the MTNL guy is at loss and there online support is practicaly non existant for last two weeks

Start > Run > cmd >ipconfig/all, check the details or post the screen shot.

After giving the command,all the tcp/ip settings of my Tata ICD are only shown.The MTNL settings are not shown at all

please use the command ipconfig/all and post the screen shot

could you post a screenshot of the SUPPORT page where the repair option is not available..

The support page
of MTNL when the Repair tab is used reads
" Windows could not finish rpairing the problem because the following action could not be completed.

TCO/IP is not enabled for this connection . Cannot proceed "

This happens inspite of giving the TCP/IP settings through the connection window via controll panel

==============================


(A)to avoid confusion use
open DNS 208.67.220.220 and 208.67.222.222
Apply Save.

or reverse the order given by you in above list

right click on local area connection ( control panel->network connections) and click on properties , there ensure that tcp/ipv4 is CHECKED

it is clear that the tata connection is superseeding the mtnl connection. disconnect the tata connection, and with the mtnl connection connected, reboot the pc. let me know how it works

unable to reach 192.168.1.1 and shows connection corrupted when i try to connect and my default gateway is empty in tuner adapter local area connection* 14
