are you trying to connect to the pc and laptop simultaneously?? if so , its not possible in bridged mode.. if not , then go to the command prompt of laptop and type ipconfig and post ouptut.. also post output of the command ping 192.168.1.1

Im not connecting both simultaneously.One at a timeThe output of ping 192.168.1.1 gives Request timed out, I did the above by giving following IPs Output of ipconfig gives 198.168.1.3IP address: 198.168.1.3Subnet mask is default valueDefault gateway is 198.168.1.1 Prefered DNS:218.248.255.14561.1.96.69The above values got from the BSNL Customer care tech personNow with no IPs assigned O/p for Autoconfig ipaddress :169.254.236.126o/p for Ping 192.168.1.1estination Host Unreachable Few days back when net was getting connected properly,I was using Dymaic IP onlyThanksSiva

1. Default gateway is 198.168.1.1
[IP address: 198.168.1.3
.........Is this the usual typing mistake ?
...........Did you enter this ?
..............Enter 192.168.1.3 .255.255.255.0 and 192.168.1.1
2.............. You have not mentioned the modem model and ...................make.
3...................Select your Modem/router from this website.
BSNL BROADBAND MAIN MENU
and check your settings.

Para two :
:169.254.236.126
private lan address assigned by OS. You will never get connected to your ISP.And default gateway is in error.

Para three: 1. You are using a dialer to connect.
2.Assuming you have not changed any settings in your modem, give proper values in laptop. ( compare with desktop)

3.You can also use open dns 208.67.220 .220 and 208.67.222.222

Error 678 is usually ID and/or PW problem.
